Technical Specifications
Fluid specifications (continued)
Features Unit 070/084/089
Filtration
(recommended
minimum)
1
Intermittent = Short term t < 1 min per incident and not exceeding 2 % of duty cycle based load-life
2
At the hottest point, normally case drain port
3
Cold start = Short term t < 3 min, p ≤ 50 bar [725 psi], n ≤ 1000 min-1(rpm)
Output Speed
Minimum speed is the lowest output speed. Operating below minimum speed limits the system can be
unstable.
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.
Cleanliness per ISO 4406 22/18/13
Efficiency (charge pressure filtration) β-ratio β15-20 = 75 (β10 ≥ 10)
Efficiency (suction and return line filtration) β35-45 = 75 (β10 ≥ 2)
Recommended inlet screen mesh size µm 100 – 125
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.
Minimum pressure must be maintained under all operating conditions to avoid cavitation.
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.
External Shaft Seal Pressure
In certain applications, the input shaft seal may be exposed to external pressures.
The shaft seal is designed to withstand an external pressure up to 0.4 bar [5.8 psi] above the case
pressure.
The case pressure limits must also 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 (cold start) temperature relates to the physical properties of component materials.
Maximum continuous temperature is the allowed temperature at which normal life can be expected.
