Hydraulic Accumulators

Hydraulic Accumulators

A hydraulic accumulator is a container or vessel, normally cylindrical, which stores hydraulic fluid or gas under pressure for future release. It enables a hydraulic system to:

  • cope with extremes of demand using a less powerful pump;
  • store power for intermittent duty cycles;
  • provide emergency or standby power (for braking and steering systems);
  • respond more quickly to a temporary demand;
  • smooth out pulsations and absorb hydraulic shock;
  • lower noise pollution;
  • compensate for leakage loss

Accumulator Charging Kit

All of which add to up extended maintenance interludes, reduced running costs and increased productivity – good news all round!

Hydraulic Accumulators

Common types of hydraulic accumulator are: piston, bladder and diaphragm. The hydraulic accumulators pictured here have been supplied to customers within the past week.  

Our most recent accumulators were despatched to a company who specialise in the services and repair of plant and hydraulics. They were 10 litre nitrile bladder accumulators with elastomeric seals. They have a maximum pressure of 345 bar. We have also dispatched a .75 litre accumulator with a maximum pressure of 350 bar, pressure on port line: 10-70 bar, maximum back pressure on tank line: 3 bar, minimum pressure: 10 bar and oil capacity of 12 litres/minute.

Not only do we supply hydraulic accumulators, but we also supply accumulator charging kits (like the one pictured here on the left)!
