Haldex AC hydraulic power unit

Product Summary

Handles a wide variety of industrial applications. All models have 1,725 RPM TEFC (totally enclosed, fan-cooled) motors, check valve, adjustable relief valve and 3,000 PSI pressure gauge. High strength cast iron housing. DU® bearings. Filler screen, sight gauge and flexible coupling. Hardened and ground alloy steel gears and shafts. Pressure-balanced pumps provide up to 90% overall efficiency. Ideal for systems using low viscosity fluids in high temps and high duty cycle applications. Pressure balanced pump provides high speed positioning and then maximum working pressure as in clamping, crimping and metal-forming machines. Does not include manifold or interface.

Haldex hydraulic power units are designed specifically to operate on AC electric power. Each power unit is a custom selected assembly consisting of a high performance hydraulic pump, reservoir, motor, manifold interface block, relief valve, pressure gauge and oil level sight gauge with thermometer. They are controlled with NFPA D03 (D01) directional control valves. Manifold and valve sold separately. The power units can be coupled via suitable hydraulic lines to a wide range of operating mechanisms. They normally operate hydraulic cylinders, but
