Carregamento e teste de unidade FPU
The HYDAC Charging and Testing Unit (FPU for short) is a testing and maintenance instrument for hydraulic accumulators. They are used to charge and test the pre-charge pressure in the accumulator or change an existing pre-charge pressure.
The FPU has a screw-type fitting with a built-in gauge, check valve and a spindle for opening the accumulator gas valve to control the pressure.
The FPU is designed to connect directly to HYDAC piston and diaphragm accumulators. Bladder accumulators however require the A3 adapter supplied.
In addition to adapters and connectors for nitrogen bottles from different countries, our range of accessories includes a carry case for storing the FPU and all the accessories and spare parts. The new, larger case protects the contents from contamination and damage, e.g. cracking of the pressure gauge on the charging unit / pressure reducer. The contents of the case can vary according to customer requirement.
Technical data FPU-1:
Material: Carbon steel, zinc-plated Max. operating pressure: 350 bar Gauge indication range: up to max. 400 bar (5800 psi)
HYDAC has expanded the accessories range to include a high pressure version of the FPU: The FPU-2 is specifically for high pressure applications.
