Universal devices for charging and testing hydraulic accumulators FPU-1
Charging and testing device
Charging and testing devices FPU-1 from the HYDAC - world leader in the production of hydraulic accumulators, are designed for checking the pressure in accumulators, accu stations, compensators, etc., as well as to fill this equipment with nitrogen.
For charging and monitoring systems with operating pressures up to 350 bar, FPU-1 or PSE modules are used. For systems with operating pressures up to 700 bar, FPU-2 devices are used.

Depending on the selected configuration, modules can be supplied with various accessories (pressure gauges, adapters for gas cylinders, adapters for accumulators, hoses, cases)
