EATON Vickers Q Series Piston Pumps Catalog V-PP-MC-0002-E December 2002

Introduction

PVQ piston pumps are in-line, variable displacement

units and are available in nine sizes. Displacement is

varied by means of pressure and/or flow compensator

controls. An impressive assortment of control options

offers maximum operating flexibility.

PVQs operate at quietness levels that meet today’s

demanding industrial conditions. The sound level of

each unit approaches or is below that of the electric

motor driving it. Sound is reduced by a patented

timing arrangement that also produces low pressure

“pulses” in the outlet flow. This leads to reduced

tendencies for noise in systems using PVQs.

The PVQ series is capable of operating with many

types of hydraulic fluid. Water-content and phosphate

ester fluids can be accommodated, in addition to the

typical petroleum based and synthetic fluids.

Many PVQ pumps are available in a thru-drive

configuration to accommodate a multitude of applica-

tion and installation requirements. Thru-drive models

can be coupled to various types and sizes of fixed and

variable displacement pumps, resulting in a compact

and versatile package. Such a package offers lower

installed cost by reducing the installation size and by

requiring only one mounting pad on the prime mover.

Quiet PVQs have excellent operating characteristics,

and the pumps’ many control and mounting options

allow choosing the optimum model for any appli-

cation. Additionally, PVQs possess the same durability

and long life characteristics expected of the best

industrial products in today’s marketplace. For over

75 years, the Eaton name has been synonymous with

long trouble-free service.

Controls

Pressure Compensators

The pressure compensator con-

trol automatically adjusts pump

delivery to maintain volume

requirements of the system at a

preselected operating pressure.

Maximum pump delivery is

maintained to approximately 3,4

bar (50 psi) below the pressure

setting before being reduced.

The pressure compensator con-

trol operates on one side of cen-

ter and has an adjustment range

as designated in the model num-

bering system.

Pressure Compensator with

Adjustable Maximum

Displacement Stop

The adjustable maximum stop

pressure control enables the

maximum pump delivery to be

externally adjusted from 25% to

100% while maintaining all of

the standard features of a pres-

sure compensated pump. To

assist initial priming, manual

adjustment control setting must

be at least 40% of maximum

flow position.

Remote Control Pressure

Compensator

Exactly the same as the “C”

(pressure compensation option)

except the machine operator is

able to change the compensator

setting through the use of a

remote pilot relief valve, such as

Eaton C-175.

Electric Dual Range Pressure

Compensator

The dual range pressure com-

pensator control automatically

adjusts pump delivery to main-

tain volume requirements of the

system at either of two prese-

lected operating pressures.

Maximum pump delivery is

maintained to approximately 3,4

bar (50 psi) below either pres-

sure control setting before being

reduced.

Control type and pressure range

are designated in the model

number system.

Note: Graphic symbols shown with external

valve(s) and cylinder to illustrate typical

usage.

Load-sensing and Pressure

Limiting Compensators

This compensator provides load-

sensing control under all pres-

sure conditions up to the

desired maximum. It automati-

cally adjusts pump flow in

response to a remote pressure

signal and maintains outlet pres-

sure at a level slightly above load

pressure. The integral pressure

limiter overrides the load-sens-

ing control, reducing pump dis-

placement as the preset maxi-

mum operating pressure is

reached.

Standard load-sense differential

pressure settings, by control

type, follow. See model number

system for setting range.

Standard load-sensing and

pressure limiting control with

11 bar differential pressure

(standard factory setting).

Includes bleed-down orifice to

exhaust load-sense signal for

low-pressure standby condition.

Same as C**V11B above, but

with bleed-down orifice plugged.

Same as C**V11B, but with fac-

tory differential pressure setting

of 24 bar.

Same as C**V11P, but with fac-

tory differential pressure setting

of 24 bar.

With the unloading valve control

the variable pump will unload at

a preset pressure. The pump will

maintain this no flow, low pres-

sure (approximately 14 bar [200

psi]) standby condition, until sys-

tem pressure drops to about

85% of the preset unloading

pressure. The pump will then

return on stroke and provide full

flow until the preset unloading

pressure is reached again.

With this control, an efficient

accumulator charging circuit is

obtained. The pump will provide

full flow to fill the accumulator

until the maximum charging

pressure is reached. The pump

then goes to a standby condition

until the accumulator pressure

drops to 85% of the desired

maximum. The accumulator is

then recharged as the cycle

starts over again.

A separate right angle check

valve must be provided to main-

tain the accumulator hydraulic

charge and prevent back flow

when the pump is unloaded. The

check valve’s internal leakage

must not exceed five drops per

minute. The control port must be

connected to system pressure,

downstream of the check valve.

Adjustment range

PVQ10 100-210 bar (1500-3000 psi)

PVQ13 100-140 bar (1500-2000 psi)

Cut-in pressure is 85% of unloading pressure,

minimum.

Setting Pressures

1. Back out accumulator un-

loading pressure adjustment

screw to below desired

unloading pressure.

2. Adjust desired standby

pressure.

3. Set accumulator pressure by

screwing in

the accumulator unloading

adjustment screw.

Accumulator recharge (cut-in)

pressure is a function of the

maximum accumulator pres-

sure and is not adjustable.

4. Check pressure settings and

re-adjust if necessary.

Controls

Pressure Compensator

Controls

The pressure compensator con-

trol automatically adjusts pump

delivery to maintain volume

requirements of the system at a

preselected operating pressure.

Maximum pump delivery is

maintained to approximately 75

psi (PVQ20) or 100 psi (PVQ32)

below the pressure setting

before being reduced. The pres-

sure compensator control oper-

ates on one side of center and

has an adjustment range as des-

ignated in the model numbering

system.

Pressure Compensator Control

with Adjustable Maximum

Displacement Stop

The adjustable maximum stop

pressure control enables the

maximum pump delivery to be

externally adjusted from 25% to

100% while maintaining all of

the standard features of a pres-

sure compensated pump. To

assist initial priming, manual

adjustment control setting must

be at least 40% of maximum

flow position.

Remote Control Pressure

Compensator

Exactly the same as the “C”

(pressure compensation option)

except the machine operator is

able to change the compensator

setting through the use of a

remote pilot relief valve, such as

Eaton C-175.

Electric Dual Range Pressure

Compensator Control

The dual range pressure com-

pensator control automatically

adjusts pump delivery to main-

tain volume requirements of the

system at either of two prese-

lected operating pressures.

Maximum pump delivery is

maintained to approximately 75

psi (PVQ20) or 100 psi (PVQ32)

below either pressure control

setting before being reduced.

Control type and pressure range

are designated in the model

number system.

Note: Graphic symbols shown with external

valve(s) and cylinder to illustrate typical

usage.

Load-sensing and Pressure

Limiter Compensator Control

This compensator provides

load-sensing control under all

pressure conditions up to the

desired maximum. It automati-

cally adjusts pump flow in

response to a remote pressure

signal and maintains outlet pres-

sure at a level slightly above load

pressure. The integral pressure

limiter overrides the load-sens-

ing control, reducing pump dis-

placement as the preset maxi-

mum operating pressure

is reached.

Standard load-sense differential

pressure settings, by control

type, follow. See model number

system for setting range.

Standard load-sensing and pres-

sure limiting control with 11 bar

differential pressure (standard

factory setting). Includes bleed-

down orifice to exhaust load-

sense signal for low-pressure

standby condition.

Same as C**V11B above, but

with bleed-down orifice plugged.

Same as C**V11B, but with fac-

tory differential pressure setting

of 24 bar.

Same as C**V11P, but with fac-

tory differential pressure setting

Unloading Valve

Control

With the unloading valve control

the variable pump will unload at

a preset pressure. The pump will

maintain this no flow, low pres-

sure (approximately 14 bar [200

psi]) standby condition, until sys-

tem pressure drops to about

85% of the preset unloading

pressure. The pump will then

return on stroke and provide full

flow until the preset unloading

pressure is reached again.

With this control, an efficient

accumulator charging circuit is

obtained. The pump will provide

full flow to fill the accumulator

until the maximum charging

pressure is reached. The pump

then goes to a standby condition

until the accumulator pressure

drops to 85% of the desired

maximum. The accumulator is

then recharged as the cycle

starts over again.

A separate right angle check

valve must be provided to main-

tain the accumulator hydraulic

charge and prevent back flow

when the pump is unloaded. The

check valve’s internal leakage

must not exceed five drops per

minute. The control port must be

connected to system pressure,

downstream of the check valve.

Controls

“G” Option

Pressure Compensator

Controls

The pressure compensator con-

trol automatically adjusts pump

delivery to maintain

volume requirements of the sys-

tem at a preselected operating

pressure. Maximum pump deliv-

ery is maintained to ap-

proximately 75 psi (PVQ025)

below the pressure setting

before being reduced. The pres-

sure compensator control

operates on one side of center

and has an adjustment range

as designated in the model num-

bering system.

Pressure Compensator Control

with Adjustable Maximum

Displacement Stop

The adjustable maximum stop

pressure control enables the

maximum pump delivery to be

externally adjusted from 25% to

100% while maintaining all of

the standard features of a pres-

sure compensated pump. To

assist initial priming, manual

adjustment control setting must

be at least 40% of maximum

flow position.

“J” Option

Remote Control Pressure

Compensator

Exactly the same as the pres-

sure compensation option,

except the machine operator is

able to change the compensator

setting through the use of a

remote pilot relief valve, such as

Eaton C-175.

“C” Option

Electric Dual Range Pressure

Compensator Control

The dual range pressure com-

pensator control automatically

adjusts pump delivery to main-

tain volume requirements of the

system at either of two pre-

selected operating pressures.

Maximum pump delivery is

maintained to approximately

75 psi (PVQ025) below either

pressure control setting before

being reduced.

Control type and pressure

range are designated in the

model number system.

Note: Graphic symbols shown with external

valve(s) and cylinder to illustrate typical

usage.

“H” Option

Load Sensing and Pressure

Limiter Compensator Control

This compensator provides

load-sensing control under all

pressure conditions up to the

desired maximum. It automati-

cally adjusts pump flow in

response to a remote pressure

signal and maintains outlet pres-

sure at a level slightly above load

pressure. The integral

pressure limiter overrides the

load-sensing control, reducing

pump displacement as the

preset maximum operating pres-

sure is reached.

Standard load-sense differential

pressure settings, by control

type, follow. See model number

system for setting range.

Standard load-sensing and pres-

sure limiting control with 11 bar

differential pressure (standard

factory setting). Includes bleed-

down orifice to exhaust load-

sense signal for low-pressure

standby condition.

Other Standard Load

Sense Options:

1. Bleed-down orifice plugged.

2. Factory differential pressure

setting of 24 bar.

Unloading Valve

Control – “E”

Option

With the unloading valve control

the variable pump will unload at

a preset pressure. The pump will

maintain this no flow, low pres-

sure (approximately 14 bar [200

psi]) standby condition, until sys-

tem pressure drops to about

85% of the preset unloading

pressure. The pump will then

return on stroke and provide full

flow until the preset unloading

pressure is reached again.

With this control, an efficient

accumulator charging circuit is

obtained. The pump will provide

full flow to fill the accumulator

until the maximum charging

pressure is reached. The pump

then goes to a standby condition

until the accumulator pressure

drops to 85% of the desired

maximum. The accumulator is

then recharged as the cycle

starts over again.

A separate right angle check

valve must be provided to main-

tain the accumulator hydraulic

charge and prevent back flow

when the pump is unloaded. The

check valve’s internal leakage

must not exceed five drops per

minute. The control port must be

connected to system pressure,

downstream of the check valve.

Pressure Limits:

Inlet pressure – 0,2 bar (5 in. Hg) vacuum to 2 bar (30 psig)

Case pressure – 0,35 bar (5 in. Hg) maximum

Note: Integral relief valve limits case pressure peaks to 0,7 bar (10 psi) higher than inlet pressure to protect pump. Flow from valve is returned directly to pump inlet.

Use of case drain line required to limit steady-state case pressure.

Note: Consult an Eaton representative for additional settings

EATON Vickers Q Series Piston Pumps Catalog V-PP-MC-0002-E December 2002

Controls

“G” Option

Pressure Compensator

Controls

This control automatically varies

pump displacement to meet the

system flow demand for a con-

stant system pressure.

Displacement starts to reduce to

zero within 14 bar (200 psi) of

the compensator setting. Power

draw-off is minimized, therefore,

system relief valves should not

be required.

Pressure Compensator Control

with Adjustable Maximum

Displacement Stop

The adjustable maximum stop

pressure control enables the

maximum pump delivery to be

externally adjusted from 25% to

100% while maintaining all of

the standard features of a pres-

sure compensated pump. To

assist initial priming, manual

adjustment control setting must

be at least 40% of maximum

flow position.

“J” Option

Remote Control Pressure

Compensator

Exactly the same as the “C”

(pressure compensation option)

except the machine operator is

able to change the compensator

setting through the use of a

remote pilot relief valve.

“C” Option

Electric Dual Range Pressure

Compensator Control

The dual range pressure com-

pensator control automatically

adjusts pump delivery to main-

tain volume requirements of the

system at either of two prese-

lected operating pressures.

Maximum pump delivery is

maintained to approximately

3,4 bar (50 psi) below either

pressure control setting before

being reduced.

Control type and pressure range

are designated in the model

number system.

Note: Graphic symbols shown with external

valve(s) and cylinder to illustrate typical

usage.

“H” Option

Load Sensing and Pressure

Limiter Compensator Control

This compensator provides load-

sensing control under all pres-

sure conditions up to the

desired maximum. It automati-

cally adjusts pump flow in

response to a remote pressure

signal and maintains outlet pres-

sure at a level slightly above load

pressure. The integral pressure

limiter overrides the load-sens-

ing control, reducing pump dis-

placement as the preset maxi-

mum operating pressure is

reached.

Standard load-sense differential

pressure settings, by control

type, follow. See model number

system for setting range.

Standard load-sensing and pres-

sure limiting control with 11 bar

differential pressure (standard

factory setting). Includes bleed-

down orifice to exhaust load-

sense signal for low-pressure

standby condition.

Other Standard Load Sense

Options:

1. Bleed-down orifice plugged.

2. Factory differential pressure

setting of 24 bar.

Adjustment

1. With the directional valve de-

energized, loosen locknut “5”

and turn the adjusting screw

“4” to the desired first stage

pressure setting, then tighten

locknut “5.”

2. With solenoid de-energized,

turn adjusting spool “1”

counterclockwise (CCW) until

nut “3” is bottomed in

adjusting screw slot. (Second

stage setting is now equal to

first stage pressure setting.)

Turn adjusting spool clock-

wise (CW) to desired second

stage pressure requirements.

One complete turn of adjust-

ing spool equals approximate-

ly 41 bar (600 psi). Energize

solenoid and check pressure

setting.

De-energize solenoid and re-

adjust if necessary. Secure

this setting by tightening

locknut “2.”

Note: Any sliding spool valve, if

held shifted under pressure for long

periods of time, may stick and not

spring return due to fluid residue for-

mation and, therefore, should be

cycled periodically to prevent this

from happening.

Controls

Unloading

Valve Control –

“E” Option

With the unloading valve control

the variable pump will unload at

a preset pressure. The pump will

maintain this no flow, low pres-

sure (approximately 14 bar [200

psi]) standby condition, until sys-

tem pressure drops to about

85% of the preset unloading

pressure. The pump will then

return on stroke and provide full

flow until the preset unloading

pressure is reached again.

With this control, an efficient

accumulator charging circuit is

obtained. The pump will provide

full flow to fill the accumulator

until the maximum charging

pressure is reached. The pump

then goes to a standby condition

until the accumulator pressure

drops to 85% of the desired

maximum. The accumulator is

then recharged as the cycle

starts over again.

A separate right angle check

valve must be provided to main-

tain the accumulator hydraulic

charge and prevent back flow

when the pump is unloaded. The

check valve’s internal leakage

must not exceed five drops per

minute. The control port must be

connected to system pressure,

downstream of the check valve.

Fluid Cleanliness

Proper fluid condition is essen-

tial for long and satisfactory life

of hydraulic components and

systems. Hydraulic fluid must

have the correct balance of

cleanliness, materials, and

additives for protection against

wear of components, elevated

viscosity, and inclusion of air.

Essential information on the cor-

rect methods for treating

hydraulic fluid is included in

Eaton publication 561 “Eaton

Guide to Systemic Contamina-

tion Control” available from your

local Eaton distributor or by con-

tacting Eaton. Recommenda-

tions on filtration and the selec-

tion of products to control fluid

condition are included in 561.

Recommended cleanliness lev-

els, using petroleum oil under

common conditions, are based

on the highest fluid pressure

levels in the system and are

coded in the chart below. Fluids

other than petroleum, severe

service cycles, or temperature

extremes are cause for adjust-

ment of these cleanliness

codes. See Eaton publication

561 for exact details.

Eaton products, as any com-

ponents, will operate with

apparent satisfaction in fluids

with higher cleanliness codes

than those described. Other

manufacturers will often recom-

mend levels above those speci-

fied. Experience has shown,

however, that life of any

hydraulic component is short-

ened in fluids with higher clean-

liness codes than those listed

below. These codes have been

proven to provide a long, trou-

ble-free service life for the

products shown, regardless of

the manufacturer.

Fire Resistant

Fluids

All pumps can be used with

water glycol and polyol ester flu-

ids. All pumps can be operated

to 140 bar (2000 psi) with these

fluids, except PVQ13 and PVQ32

which are limited to

105 bar (1500 psi). Input speed

should not exceed 1800 r/min.

System temperature should not

exceed 54° C (130° F). Inlet vac-

uum should not exceed

101,6 millibar (3 in. Hg). For

more information, refer to Eaton

publication 579.

Installation

and Start-up

(Commissioning)

Before a pump is started, fill

the case through the uppermost

drain port with hydraulic oil of

the type to be used. The case

drain line must be connected to

the reservoir below oil level.

For multiple pump arrangements

that include non-PVQ sections,

the requirements of the non-

PVQ units must be considered.

Ordering

Procedure

Order pumps by the full model

designation. Pump displace-

ment, mounting flange type,

direction of rotation, pump

configuration, shaft end type,

seals, pressure adjustment

range, and specific control

functions are all specified in the

full model number system.

Couplings, O-rings, capscrews

and washers must be ordered

separately for all thru-drive

pumps.
