Hydraulic power pack with LS variable and constant displacement pump combination
The hydraulic power pack is suitable for all basic experiments in mobile hydraulics. Both pumps are powered by a single electric motor.
The controllable axial piston pump has a load-sensing pump controller. The constant displacement pump is protected by a pressure relief valve.
The motor-pump unit is located on top of the tank. There’s a return filter in the return line to the tank. The tank vent is also filtered. The oil level can be read at the sight glass with temperature indicator.
The motor is switched on and off with an on/off switch. The motor is protected against overloading, and is secured against restart after power failure.
