Why Use Diaphragm Accumulators
Diaphragm accumulators provide an affordable means of enhancing the performence of a hydraulic system. They are suitable for storing energy under pressure, absobing hydraulic shocks, and dampening pump pulsation and flow fluctuations with the following characteristics:
- Improves system efficiency
- Supplement pump flow
- Supplies power in emergency
- Compensates for leakage
- Absorbs hydraulic shocks
- Works well with water, low lubricity fluids
- Very contamination tolerant
- Cost effective
- Compact, lightweight
- Safety, non-repairable design
- Very quick response
