Filling and testing device HFP

HENNLICH filling and testing devices are used for filling hydraulic accumulators with nitrogen and for checking or adjusting the precharge pressure. They can be utilized for bladder, membrane, and piston accumulators from nearly all manufacturers on the market. The filling and testing device is either directly screwed onto the hydraulic accumulator (for membrane accumulators) or attached via adapters (for bladder and piston accumulators). It is connected to a standard nitrogen cylinder using the corresponding hose. For purely checking or reducing the precharge pressure, connection to the gas cylinder is not necessary.
