. Handling Precautions

1. Operating Fluid and

Temperature Range

1) Operating uid

Values shown in this catalog are based upon using

mineral oil based anti-wear hydraulic uid. To

ensure optimal performance use of mineral oil

based anti-wear hydraulic uid is recommended.

2) Viscosity and temperature range

To minimize both oil and seal deterioration, a

maximum operating temperature of 60

should

be considered. Please note that the regulator

may become slow to respond when operating

at low temperatures (below 20

) in extreme

cold environments. At such low temperature it

is strongly suggested that a warm up cycle is

introduced until an operating temperature of 20

is achieved.

2. Filtration and Contamination

Control

1) Filtration of working oil

The most important means to prevent premature

damage to the pump and associated equipment

and to extend its working life, is to ensure that

hydraulic uid contamination control of the system

is working effectively.

This begins by ensuring that at the time of

installation that all piping, tanks etc. are rigorously

cleaned in a sanitary way. Flushing should be

provided using an off line ltration system

and after ushing the lter elements sh

ould be

replaced.

2) Suggested acceptable contamination

level

The relationship between contamination level and

pump life is very difcult to predict as it depends

on the type and nature of the contaminant present

in the system. Sand or Silica in particular, due to

its abrasive nature, does signicantly reduce the

expected life of a pump. Based on the precondition

that there is no signicant presen

ce of Silica type

substances then a minimum Cleanliness level of

-/18/15 ISO 4406 or SAE AS 4059E Table 1 Class 9

(NAS 1638 Class 9).

5

3. Drive Shaft Coupling

Alignment between the prime mover and the pump shaft should be within a tolerated margin, that is,

parallel misalignment within 0.05mm TIR* and angular misalignment within 0.2

TIR*. In case the pump is

directly coupled to the engine ywheel, use a exible coupling.

*TIR = Total Indicator Reading

4. Oil Filling and Air Bleeding

1) Pump case lling

Be sure to ll the pump casing with oil through the drain port, lling only the suction line with oil is totally

in-sufcient. The pump contains bearings and high-speed sliding parts including pistons with shoes and a

spherical bush that need to be continuously lubricated. Part seizure or total premature failure will occur

very quickly if this procedure is not rigidly followed.

2) Air bleeding

Run the pump unloaded for a period to ensure that all residual air within the system is released.

3) Long term out of usage

It is undesirable to leave the pump out of use for a long period e.g. a year or more. In such a situation it is

recommended that the pump is run for a short period on a more frequent basis even if it is just unloaded.

With regard to a pump held in storage then rotating the shaft on a frequent basis is sufcient.

If the pump is

left out for more than the suggested time it will require a service inspection.

5. Drain Piping

1) Installation of drain line

It is the preferred option to mount the pump with the case drain piping initially rising above the pump

before continuing to the tank. Do not connect the drain line to the inlet line.

2) Size of drain hose or drain pipe

The internal bore size of the drain hose or drain pipe must be larger than that of the drain port. Arrange the

drain line as sh

ort as possible.

The uppermost drain port should be used and the drain piping must be larger in size than the drain port

to minimize pressure in the pump case. The pump case pressure must not exceed 0.2 MPa as shown in the

illustration below. (Peak pressure most never exceed 0.6 MPa.)

Cautions

A) Inlet and drain pipes must be immersed by

200 mm minimum from the lowest level under

operating conditions

.

B) Height from the oil level to the centre of the

shaft must be within 1 meter maximum.

C) The oil in the pump case must be relled when

the pump has not been operated for one month

or longer.

6. Mounting the Pump Above the Tank

When installing the pump above the tank, please ensure to connect the charge inlet line as shown below and

ll it with hydraulic uids.

7. Shaft Loading and Bearing Life

Although K8V pumps are equipped with bearings that can accept some external radial forces, exertion of

external radial loads will affect bearing life. Depending on the load magnitude, the load pos

ition, and the

load orientation, bearing life may be inuenced and reduced.

Consult with Kawasaki for further details.

8. Minimum Boost Pressure

The K8V series pump requires the minimum boost pressure of 2.0 MPa in the low pressure line in order to

provide stable control. In addition, setting value of the charge pressure should be lower than that of the low

pressure relief valve.

1. High pressure relief valve

High pressure relief valves (two valves) are

equipped to protect the pump from being

overloaded.

The high pressure relief valves act to protect the

pump from pressure spikes in dynamic control

situations and are not equipped for continuous

operation.

Customized pressure setting for a special case

Please contact Kawasaki.

Note:

The allowable setting range of the high pressure

relief valve is from 30 MPa to 45 MPa, and the

customized pressure must be set within this range.

For the customized pressure setting contact

Kawasaki with the required pressure setting value.

The pressure of the high pressure relief v

alve is

factory preset at 40 MPa, if not specied.

2. Low pressure relief valve

Low pressure relief valve is equipped to control

the pressure for charge line and servo line.

The pressure setting of an integrated low pressure

relief valve is preset at 2.5 MPa at the factory.

Do not adjust the pressure of the low pressure

relief valve, as it may reduce the controllability of

the pump.

Pressure Cut-off

Pressure cut-off is the function which adjusts the

pump displacement to the neutral position when

the pressure reaches its pressure setting.

The pressure cut-off is set lower than high pressure

relief valve setting, so that the maximum pump

pressure is controlled by the pressure cut-off valve,

whereas the high pressure relief valve acts to the

pressure spike.

The cut-off pressure must be set at leas

t 5 MPa

lower than the setting of the high pressure relief

valves.

The allowable setting range of the cut-off pressure

is from 30 MPa to 40 MPa.

Charge Pump

Charge ow is required on all K8V pumps applied in closed circuit systems. The charge pump supplies ow

to replenish, cool and lter oil, provide charge pressure and servo pressure, and ow for system control and

auxiliary functions.

The integrated charge pump is available. The available charge pump sizes are as follows;

K8V71/90: 20 cm

3

/rev

K8V125: 28 cm

/rev

Pressure and ow for charge

circuit can be supplied by an external auxiliary pump.

An auxiliary pump for charge circuit can also be mounted on the back of main pump using through drive

mounting.

In case the auxiliary pump is used for charge circuit, connect the charge pump delivery line to port C so that

the ow is provided to the low pressure line and servo line. The integrated low pressure relief valve can be

used in this

case. If the integrated low pressure relief valve is not used, provide an appropriate relief valve

in the system.

2-2 Functional Description of Regulator

Electric Proportional Control

(Ordering code [14] : P1, P2)

Pump delivery ow can be proportionally controlled by the

input current to the electric proportional reducing valve

equipped on the regulator.

The input current of the electric proportional reducing valve

signals the control spool in a regulator to stroke, and to supply

pressure to the servo piston

. The pump displacement varies

with the stroke of the servo piston.

The feedback lever, connected with the servo piston at the

one end, moves with the stroke of the servo piston. This

movement causes the sleeve of the control spool which is

connected to the other end of the feedback lever to stroke,

and closes the ow passage to the servo piston.

Consequently, the stroke of the servo piston stops, a

nd the

pump displacement becomes proportional to the input current.

2-2 Functional Description of Regulator

Hydraulic Pilot Displacement Control (Ordering code [14] P3)

Pump delivery ow can be proportionally

controlled by the external pilot pressure supply.

The external pilot pressure signals the control spool

in a regulator to stroke, and to supply pressure to

the servo piston. The pump displacement varies

with the stroke of the servo piston.

Th

e feedback lever, connected with the servo

piston at the one end, moves with the stroke of the

servo piston. This movement causes the sleeve of

the control spool which is connected with the other

end of the feedback lever to stroke, and closes the

ow passage to the servo piston.

Consequently, the stroke of the servo piston stops,

and the pump displacement becomes proportional

to the external pilot

pressure.

The above gure is the standard control characteristic of hydraulic pilot displacement control.

If non standard control characteristics is required, please contact Kawasaki.

Mechanical Stroke Limiter

Mechanical stroke limiter is available for option. By an adjusting screw the maximum displacement can be

adjusted innitely to the required displacement setting.

This option is under development. For details contact Kawasaki.

Stroking Speed Control Orice

Pump stroking speed (response) can be adjusted by changing the control orice which is integrated in the

servo line. The available control orices and those response (for reference) are shown in the table below.

Allowable mass moment for combination pump

K8V series allows combination of multiple pumps

using through drive mounting. Any pump up to the

same size of the rst pump may be mounted to the

rst pump.

In case of tandem conguration comprising of

two pumps of the same rated size the allowable

maximum dynamic acceleration to the pump unit is

10G. No additional mounting support is necessary

in conn

ecting two pumps, but use a 4-bolt mounting

on the rst pump when installing the pump unit.

If the third pump is to be mounted on the rear of

the second pump, the pump mass moment at the

mounting ange shall be within the rated mass

moment. Also, the input torque on the shaft needs

to be within the limit of input torque tolerance. (See

"Allowable maximum input torque" on page 13)
