Central Hydraulic Power Systems Manufacturers

Central hydraulic supply system consists of two or more electrically driven pumps delivering oil at pressure and connected to accumulator, which are normally of the piston displacement type. The accumulator piston is backed on the other side by high-pressure air supplied by air bottles, which need to be topped up from the air system from time to time. Switches are controlled by the displacement of the piston so that the pumps is switched of when the accumulators are fully charged and only switched on when the accumulators are approaching the exhaustion point and pressure has dropped to the lower limit.
