Pump installation position is discretionary; however the recommended control
position is on the top.
The housing must always be filled with hydraulic fluid.
Pump shaft connection is discretionary, however it is strongly recommended to use
rubber coupling if pump is driven via “cardan” shaft.
Correct installation has a significant influence on a life time of the pump.

Input speed
Minimum speed is the lowest input speed recommended during engine idle condition. Operating below
minimum speed limits the pump’s ability to maintain adequate flow for lubrication and power
transmission.
Rated speed is the highest input speed recommended at full power condition. Operating at or below this
speed should yield satisfactory product life.
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.
System pressure
Maximum working pressure is the highest recommended application pressure; and it 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.
Caution
Minimum pressure must be maintained under all operating conditions to avoid cavitation.

Charge pressure
Minimum charge pressure is the lowest pressure allowed to maintain a safe working condition in the low
side of the loop.
Maximum charge pressure is the highest charge pressure allowed by the charge relief adjustment, which
provides normal component life.
Charge pump inlet pressure
Minimum charge inlet pressure is only allowed at cold start conditions. In some applications it is
recommended to warm up the fluid (e.g. in the tank) before starting the engine and then run the engine
at limited speed. Maximum charge pump inlet pressure may be applied continuously.
Caution
At normal operating temperature, charge inlet pressure must not fall below rated charge inlet pressure
(vacuum).
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.
Hydraulic fluid specifications
External shaft seal pressure
The shaft seal is designed to withstand an external pressure up to 0.4 bar [5.8 psi] above the case
pressure. In certain applications, the input shaft seal may be exposed to external pressures.
Caution
The case pressure limits must be followed to ensure the shaft seal is not damaged.
Temperature
High temperature limits apply at the inlet port of the motor. The motor should run at or below the
maximum continuous temperature.
Cold oil generally does not affect the durability of motor components. It may affect the ability of oil to
flow and transmit power. For this reason, keep the temperature at 16°C [60 °F] above the pour point of
the hydraulic fluid.
Minimum temperature (cold start) relates to the physical properties of component materials.
Maximum continuous temperature is the allowed temperature at which normal life can be expected.
Peak temperature (intermittent) is the overheating temperature tolerable by the machine for a transient/
limited time.
Viscosity
Minimum viscosity occurs only during brief occasions of maximum ambient temperature and severe duty
cycle operation. It’s the minimum acceptable viscosity to allow normal motor life.
Maximum viscosity occurs only during cold start at very low ambient temperatures. It’s the upper limit of
viscosity that allows the motor to start.
Temperature and viscosity requirements must be concurrently satisfied. Use petroleum/mineral-based
fluids.

Filtration
To prevent premature wear, ensure only clean fluid enters 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.
These cleanliness levels can not be applied for hydraulic fluid residing in the component housing/case or
any other cavity after transport.
Filtration strategies for TMP include only suction filtration. 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 can 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 β35-45 = 75 (β10 ≥ 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 β15-20
= 75 (β10 ≥ 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 Technical Information,
520L0467 for more information.

Technical Information TMP Transit Mixer Axial Piston Pump, Size 070/089
Technical specifications
Case Drain
All TM pumps are equipped with two case drain ports. Port selection and case drain routing must enable
the pump housing to maintain a volume of oil not less than half full and normal operating case pressure
limits of the unit are maintained. Case drain routing and design must consider unit case pressure ratings.
A case drain line must be connected to one of the case outlets to return internal leakage to the system
reservoir.
Reservoir
The reservoir provides clean fluid, dissipates heat, removes entrained air, and allows for fluid volume
changes associated with fluid expansion during system operation. A correctly sized reservoir also
accommodates maximum volume changes during all system operating modes. It promotes de-aeration
of the fluid as it passes through, and accommodates a fluid dwell-time between 60 and 180 seconds,
allowing entrained air to escape.
Minimum reservoir capacity depends on the volume required to cool and hold the oil, allowing for
expansion due to temperature changes. A fluid volume of one to three times the motor output flow (per
minute) is satisfactory. The minimum recommended reservoir capacity is 125% of the fluid volume.
Put the return-line below the lowest expected fluid level to allow discharge into the reservoir for
maximum dwell and efficient de-aeration. A baffle (or baffles) between the return and suction lines
promotes de-aeration and reduces fluid surges.
