Hydraulic Accumulator Test Bench

Hytec Fluid Technology has a hydraulic accumulator test bench housed within its accumulation certification centre. The test bench and centre are used to help Hytec Fluid Technology and Bosch Rexroth South Africa Group of Companies customers subject their accumulators to internal and external inspections, as well as hydrostatic pressure tests. HFT is authorised to provide certification of manufacture and the verification signature of an Approved Inspection Authority.

Hydraulic accumulators

All of our accumulators are hydraulic accumulators which provide the numerous advantages and benefits as listed below.

Advantages and benefits of piston accumulators:

  • Adaptation to high temperatures
  • Adaptable in transfer systems
  • Piston position indicator
  • High compression ratios
  • Customised capacities

Advantages and benefits of diaphragm accumulators:

  • High compression ratios
  • Instantaneous response times
  • Can be mounted in any orientation
  • Minimal maintenance requirements
  • Compact design

Advantages and benefits of bladder accumulators:

  • Instantaneous response times
  • Adaptation low and high temperatures
  • Adaptation to the different fluids
  • Wide pressure range
  • Horizontal or vertical installation

In addition to piston, diaphragm and bladder accumulators, we have accessories, dampers and charging kits! Contact us to find out more.

Accumulator accessories

Our range of accumulator accessories includes accumulator charging valves or pressure shut-off valves, that keep a pressure level in an accumulator circuit within certain limit values. We also stock an accumulator safety block that should be used for isolating and unloading functions in hydraulic accumulators.

Hydraulic dampers

Hydraulic dampers from Hydac are ideal for all damping that include pressure fluctuation that can damage measuring instruments.

Charging kits

Hytec Fluid Technology stocks a range of Universal Unit charging kits, VG3 Unit charging kits and VGU Unit charging kits from Hydac and Olaer. They are used for charging bladder and piston accumulators with nitrogen, and for testing or changing the existing pre-charge pressure. All of these charging and testing kits are suitable for bladder, piston and diaphragm accumulators and comprise:

  • Valve body
  • Spindle
  • Check valve
  • Release valve
  • Pressure gauge
  • Charging hose
  • A3 adapter for bladder accumulators
