A low-noise DC hydraulic power unit for pallet trucks and compact material-handling equipment, with solenoid-controlled lowering and a balance valve. Available in 12VDC and 24VDC.
This power unit consists of a high-pressure gear pump, low-noise DC motor, multifunctional manifold, valves and tank. It is suitable for compact material-handling equipment such as pallet trucks and small stackers. Lowering is controlled by a solenoid valve, and lowering speed is regulated by the balance valve.

Precautions
S3 intermittent duty: 30 seconds on and 270 seconds off. Continuous operation is not permitted.
Clean all hydraulic components, cylinders, hoses and fittings before installing the power unit.
Use clean hydraulic oil free of impurities, with a viscosity of 15-68 cSt. N46 hydraulic oil is recommended.
Mount the power unit vertically.
Check the oil level in the tank after the initial operation of the power unit.
Change the hydraulic oil after the first 100 operating hours and every 3,000 hours thereafter.
