Pressure Vessels
Accumulators (Necked-in)
Hydraulic accumulators for energy storage and pressure stabilisation in hydraulic systems. Widely used in marine hydraulic equipment, steering gear systems and deck machinery.
Key Features
- Energy storage — assists pump source, provides instant high flow on demand
- Absorbs pulsation — reduces system pressure fluctuation and shock
- Bladder, piston and diaphragm types available
- Shell material: high-strength alloy steel
- Bladder material: NBR or FKM
