Series 90 Family of Pumps and Motors
Series 90 hydrostatic pumps and motors can be applied together or combined with other products in a
system to transfer and control hydraulic power. They are intended for closed circuit applications.
Series 90 variable displacement pumps are compact, high power density units. All models utilize the
parallel axial piston/slipper concept in conjunction with a tiltable swashplate to vary the pump's
displacement. Reversing the angle of the swashplate reverses the flow of oil from the pump and thus
reverses the direction of rotation of the motor output.
Series 90 pumps include an integral charge pump to provide system replenishing and cooling oil flow, as
well as control fluid flow. They also feature a range of auxiliary mounting pads to accept auxiliary
hydraulic pumps for use in complementary hydraulic systems. A complete family of control options is
available to suit a variety of control systems (mechanical, hydraulic, electric).
Series 90 motors also use the parallel axial piston/slipper design in conjunction with a fixed swashplate.
They can intake/discharge fluid through either port; they are bidirectional. They also include an optional
loop flushing feature that provides additional cooling and cleaning of fluid in the working loop.

Overview
Maintain operating parameters within prescribed limits during all operating conditions. This section
defines operating limits given in the table Operating Parameters on page 8.
Speed Limits
Continuous speed is the highest input speed recommended at full power condition. Operating at or below
this speed should yield satisfactory product life. In a machine propel application, maximum motor speed
during unloaded, on - road travelling on level ground should not exceed this limit.
Maximum speed is the highest operating speed permitted. Exceeding maximum speed reduces product
life and can cause loss of hydrostatic power and braking capacity. Never exceed the maximum speed
limit under any operating conditions.
Consult Pressure and speed limits BLN-9884, when determining speed limits for a particular application.
W
Warning
Unintended vehicle or machine movement hazard.
Exceeding maximum speed may cause a loss of hydrostatic drive line power and braking capacity. You
must provide a braking system, redundant to the hydrostatic transmission, sufficient to stop and hold the
vehicle or machine in the event of hydrostatic drive power loss.
System Pressure
System pressure is the differential pressure between high pressure system ports. It is the dominant
operating variable affecting hydraulic unit life. High system pressure, which results from high load,
reduces expected life. Hydraulic unit life depends on the speed and normal operating, or weighted
average, pressure that can only be determined from a duty cycle analysis.
Application pressure is the high pressure relief or pressure limiter setting normally defined within the
order code of the pump. This is the applied system pressure at which the drive-line generates the
maximum calculated pull or torque in the application.
Maximum working pressure is the highest recommended Application pressure. Maximum working
pressure is not intended to be a continuous pressure. Propel systems with application pressures at, or
below, this pressure should yield satisfactory unit life given proper component sizing.
Maximum pressure is the highest allowable Application pressure under any circumstance. Application
pressures above maximum working Pressure will only be considered with duty cycle analysis and factory
approval.
Pressure spikes are normal and must be considered when reviewing maximum working pressure.
Minimum low loop pressure must be maintained under all operating conditions to avoid cavitation.
All pressure limits are differential pressures referenced to low loop (charge) pressure. Subtract low loop
pressure from gauge readings to compute the differential.
Servo Pressure
Servo pressure is the pressure in the Servo-system needed to position and hold the pump on stroke. It
depends on system pressure and speed.
At minimum servo pressure the pump will run at reduced stroke depending on speed and pressure.
Minimum servo pressure at corner power holds the pump on full stroke at max speed and max pressure.
Maximum servo pressure is the highest pressure typically given by the charge pressure setting.

Danfoss | January 2017 520L0604 | BC00000017en-US0605
Case Pressure
Under normal operating conditions, the rated case pressure must not be exceeded. During cold start
case pressure must be kept below maximum intermittent case pressure. Size drain plumbing accordingly.
W
Warning
Possible component damage or leakage
Operation with case pressure in excess of stated limits may damage seals, gaskets, and/or housings,
causing external leakage. Performance may also be affected since charge and system pressure are
additive to case pressure.
Hydraulic Fluids
Ratings and data are based on operating with hydraulic fluids containing oxidation, rust and foam
inhibitors. These fluids must possess good thermal and hydrolytic stability to prevent wear, erosion, and
corrosion of pump components. Never mix hydraulic fluids of different types.
Fire resistant fluids are also suitable at modified operating conditions. Please see Danfoss publication
520L0463 for more information. Refer to publication 520L0465 for information relating to
biodegradable fluids.
Suitable Hydraulic fluids:
•
Hydraulic fluids per DIN 51 524, 2-HLP,
•
Hydraulic fluids per DIN 51 524, 3-HVLP,
•
API CD, CE and CF engine fluids per SAE J183,
•
M2C33F or G automatic transmission fluids (ATF),
•
Dexron II (ATF), which meets the Allison C3- and Caterpillar TO-2 test,
•
Agricultural multi purpose oil (STOU),
•
Premium turbine oils.
Temperature and Viscosity
Temperature and viscosity requirements must be concurrently satisfied. The data shown in the table Fluid
Specifications on page 9, assume petroleum-based fluids are used.
The high temperature limits apply at the hottest point in the transmission, which is normally the motor
case drain. The system should generally be run at or below the rated temperature. The maximum
temperature is based on material properties and should never be exceeded.
Cold oil will generally not affect the durability of the transmission components, but it may affect the
ability of oil to flow and transmit power; therefore temperatures should remain 16 °C [30 °F] above the
pour point of the hydraulic fluid. The minimum temperature relates to the physical properties of
component materials.
For maximum unit efficiency and bearing life the fluid viscosity should remain in the recommended
operating range. The minimum viscosity should be encountered only during brief occasions of
maximum ambient temperature and severe duty cycle operation. The maximum viscosity should be
encountered only at cold start.
Heat exchangers should be sized to keep the fluid within these limits. Testing to verify that these
temperature limits are not exceeded is recommended.

Fluid and Filtration
To prevent premature wear, it is imperative that only clean fluid enter the hydrostatic transmission
circuit. A filter capable of controlling the fluid cleanliness to ISO 4406 class 22/18/13 (SAE J1165) or better
under normal operating conditions is recommended.
The filter may be located either on the inlet (suction filtration) or discharge (charge pressure filtration)
side of the charge pump. The selection of a filter depends on a number of factors including the
contaminant ingression rate, the generation of contaminants in the system, the required fluid cleanliness,
and the desired maintenance interval. Filters are selected to meet the above requirements using rating
parameters of efficiency and capacity.
Filter efficiency may be measured with a Beta ratio (βX).
Filter βx-ratio is a measure of filter efficiency defined by ISO 4572. It is defined as the ratio of the number
of particles greater than a given diameter (“x” in microns) upstream of the filter to the number of these
particles downstream of the filter.
For simple suction-filtered closed circuit transmissions and open circuit transmissions with return line
filtration, a filter with a β-ratio within the range of β
35-45
= 75 (β
10
≥ 2) or better has been found to be
satisfactory. For some open circuit systems, and closed circuits with cylinders being supplied from the
same reservoir, a considerably higher filter efficiency is recommended. This also applies to systems with
gears or clutches using a common reservoir. For these systems, a charge pressure or return filtration
system with a filter β-ratio in the range of β
15-20
= 75 (β
10
≥ 10) or better is typically required.
Because each system is unique, only a thorough testing and evaluation program can fully validate the
filtration system. Please see Design Guidelines for Hydraulic Fluid Cleanliness 520L0467, for more
information.
Independent Braking System
W
Warning
Unintended vehicle or machine movement hazard.
The loss of hydrostatic drive line power, in any mode of operation (forward, neutral, or reverse) may cause
the system to lose hydrostatic braking capacity. You must provide a braking system, redundant to the
hydrostatic transmission, sufficient to stop and hold the vehicle or machine in the event of hydrostatic
drive power loss.
Reservoir
The reservoir should be designed to accommodate maximum volume changes during all system
operating modes and to promote de-aeration of the fluid as it passes through the tank.
A suggested minimum total reservoir volume is 5/8 of the maximum charge pump flow per minute with a
minimum fluid volume equal to 1/2 of the maximum charge pump flow per minute. This allows 30
seconds fluid dwell for removing entrained air at the maximum return flow. This is usually adequate to
allow for a closed reservoir (no breather) in most applications.
The reservoir outlet to the charge pump inlet should be above the bottom of the reservoir to take
advantage of gravity separation and prevent large foreign particles from entering the charge inlet line. A
125 mm screen over the outlet port is recommended.
The reservoir inlet (fluid return) should be positioned so that flow to the reservoir is discharged below the
normal fluid level, and also directed into the interior of the reservoir for maximum dwell and efficient de-
aeration. A baffle (or baffles) between the reservoir inlet and outlet ports will promote de-aeration and
reduce surging of the fluid.

Overpressure Protection
Series 90 motors (as well as other system components) have pressure limitations. As Series 90 motors are
not equipped with overpressure protection, it is necessary that relief valves or pressure limiters are
present elsewhere in the high pressure circuit to protect components from excessive pressures.
Series 90 pumps are designed with a sequenced pressure limiting system and high pressure relief valves.
When the preset pressure is reached, the pressure limiter system acts to rapidly de-stroke the pump in
order to limit the system pressure. For unusually rapid load application, the high pressure relief valve
function is available to also limit the pressure level. Refer to publication Series 90 Pumps Technical
Information Manual 520L0603 for more information.
For systems with relief valves only, high pressure relief valves are intended for transient overpressure
protection and are not intended for continuous pressure control. Operation over relief valves for
extended periods of time may result in severe heat build up. High flows over relief valves may result in
pressure levels exceeding the nominal valve setting and potential damage to system components.
Case Drain
A case drain line must be connected to one of the case outlets (L1 or L2) to return internal leakage and
loop flushing flow to the system reservoir. The higher of the two case outlets should be used to promote
complete filling of the case. Since case drain fluid is typically the hottest fluid in the system, it is
advantageous to return this flow through the heat exchanger.
Sizing Equations
The following equations are helpful when sizing hydraulic motors. Generally, the sizing process is
initiated by an evaluation of the machine system to determine the required motor speed and torque to
perform the necessary work function. Refer to Selection of drive line components BLN-9985, for a more
complete description of hydrostatic drive line sizing. First, the motor is sized to transmit the maximum
required torque. The pump is then selected as a flow source to achieve the maximum motor speed.

External Shaft Loading and Bearing Life
In vehicle propel drives with no external shaft loads where the system pressure is changing direction and
magnitude regularly and the operating parameters are within the limits, the normal L20 bearing life (80%
survival) will exceed the hydraulic life of the unit.
In non-propel drives such as vibratory drives, conveyor drives or fan drives, the operating pressure is
often constant. These drives have unique duty cycles compared to a propel drive. In these types of
applications a bearing life review is recommended.
In a bearing life analysis the following parameters are considered: Speed, pressure and external loads.
Other factors that affect life include fluid type, viscosity and cleanliness.

Applications with external shaft loads
Avoid external thrust (axial) loads in either direction whenever possible. Thrust loads could reduce the
bearing life in applications with low delta system pressure or when present in combination with radial
loading or bending moments.
External loads are found in applications where the motor is driven with a radial load on the shaft (i.e. belt
or gear driven) as well as installations with misalignment or improper concentricity between the motor
and drive coupling. All external loads will act to reduce the normal bearing life of a motor.
In applications where external radial shaft loads cannot be avoided, minimize the impact on bearing life
by orienting the load to the 180° position as shown in the figure below when possible. Use tapered
output shafts or clamped-type couplings where radial shaft loads are present.

Loop Flushing
W
Warning
Unintended vehicle or machine movement hazard.
Excessive motor loop flushing flow may result in the inability to build required system pressure in some
conditions. Maintain correct charge pressure under all conditions of operation to maintain pump control
performance in hydrostatic systems.
An integral non-adjustable loop flushing valve is incorporated into Series 90 motors. Installations that
require fluid to be removed from the low pressure side of the system circuit because of cooling
requirements or contamination removal will benefit from loop flushing.
The integral loop flushing valve is equipped with an orificed charge pressure relief valve designed with a
cracking pressure of 16 bar [232 psi]. Valves are available with several orifice sizes to meet the flushing
flow requirements of all system operating conditions.
The total system charge pump flow should be of sufficient volume to accommodate:
•
The number of motors in the system
•
System efficiency under worst case conditions
•
Pump control requirements
•
External needs
Although charge pump sizing requires the consideration of many system variables, the following table
gives a recommendation of what charge pump displacement may be required to accommodate the
flushing flow of each available charge relief valve orifice.

Speed Sensor
An optional speed sensor for direct measurement of speed is available. This sensor may also be used to
sense the direction of rotation.
A special magnetic ring is pressed onto the outside diameter of the cylinder block and a Hall effect sensor
is located in the motor housing. The sensor accepts supply voltage and outputs a digital pulse signal in
response to the speed of the ring. The output changes its high/low state as the north and south poles of
the permanently magnetized speed ring pass by the face of the sensor. The digital signal is generated at
frequencies suitable for microprocessor based controls.The sensor is available with different connectors
(see below).

Torque ratings assume no external radial loading. Continuous torque ratings for splined shafts are based
on spline tooth wear, and assume the mating spline has a minimum hardness of Rc 55 and full spline
depth with initial lubrication. Maximum torque ratings are based on fatigue and assume 200 000 load
reversals. The permissible continuous torque may approach the maximum rating if the spline is
immersed in circulating oil.

Recommended mating splines for Series 90 splined output shafts should be in accordance with ANSI
B92.1 Class 5. Danfoss external splines are modified class 5 fillet root side fit. The external spline major
diameter and circular tooth thickness dimensions are reduced to assure a clearance fit with the mating
spline. Contact your Danfoss representative for other splined shaft options.
