The Mini Power unit has a single acting hydraulic circuit, the
check valve and dolenoid valve hold the cylinder load up.
A high quality hardened steel check valve insert ensures low
leakage and excellent load holding. Versions with Normally
open/closed solenoid check valves and low noise check valves are
All of these mini hydraulic power packs have a precision engineered
aluminium manifold that houses the hardened steel valves. A
carefully developed micro hydraulic pump gives pressures up to
200bar. Each manifold has an integrated 90 micron filter element,
ensuring all hydraulic systems are protected and give a long
To drive the hydraulic pumps we offer DC motors from 150 to
800Watt, in 12V and 24VDC. 150 and 250Watt Fractional Horsepower AC
motors as well as standard IEC frame AC motors from 0.18kW to
Pump sizes range from 0.17cc to 1.48cc/rev.
Tanks from 0.1 to 1 Litre, all of which can be in vertical (tank
uppermost) or horizontal orientation.
Manual control for cylinder operation can be inculded.
An inbuilt throtting valve is available at the oil return port
which keeps the hydraulic device descending steadily and ata
This design also provides our hydraulic power units with simple
operation and convenient maintenance as well as good pressure

1.Before installation, please make sure that there are no any
impurities in the oil tank, oil pipe and joints.
The contamination degree of hydraulic oil should not exceed ISO
4406 18/14. The hydraulic oil should be filtered by a 10-30um
filter before put into use. The oil viscostity should be 22-46
mm2/s in accordance with ISO3448 viscosity classification.
2. To achieve thermal equilibrium of the electric motor, we have to
assure that the ratio between interval time and operation time of
the hydraulic power unit is : 1: 9.
3. This small elevator hydraulic power unit is in line with
4. Have an oil change after first 100 working hours of the hyraulic
power pack, and then every 300 working hours.
