Hydraulic accumulator production

We design and produce accumulators according to the customers’ specifications, delivered in most types of materials. For example limit switches, burst disc, external and internal position sensor, accumulators for subsea use, etc. Accumulators are produced in the dimensions Ø 40, Ø 700 mm to 1500 bars (the upper limit for type approval). The accumulators > 1L are CE approved according to PED-61-B. The approvals also cover pressure tanks.
