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.

Low cost, welded diaphragm accumulators - Type AMS

Servi Group, with more than 100 years’ experience in hydraulics and constant innovation, is now able to offer a new range of welded diaphragm accumulators – AMS. The accumulator body is manufactured with electron beam welded, high strength alloy steel. Inside is fitted a Nitrile (perbunan) diaphragm for the separation between gas and fluid. Specially designed for a variety of applications, the AMS is a low costs alternative that is less expensive to replace than would a repairable accumulator be to repair. Therefore, the AMS-range is preferably used as shock absorbers and pulsation dampers for industrial and mobile applications, as well as safety and pressure holding functions, when volume requirements are small.
