Accumulators
Hydraulic Accumulators regulate the performance of a hydraulic system by providing an additional volume of system fluid, pressurized by an external gas supply. For industrial applications, we offer following types of hydro-pneumatic accumulators: bladder, diaphragm, pulsation dampener and piston.
Each type has particular advantages and limitations, which should be considered when selecting an accumulator for a specific application.
Accumulators are available with wide variety of
- Materials for specialized applications – carbon steel of many grades, stainless steel etc.
- Seal materials and configurations available.
- Plating – Nickel and chrome plating, and epoxy/anti-corrosive coatings available.
- Connections – from standard threaded and flange port connections to specialised flange connections.
- Position measurement (possible with piston accumulator only) – Proximity switches, linear transducers, or mechanical indicating rods available for identifying piston location.
Apart from Accumulators, we also offer related Accessories for safe operation, mounting and handling of these Accumulators.
Bladder Type Accumulator
Bladder Type Accumulator is a pressure storage reservoir in which a non-compressible fluid is held under pressure by an inert gas source (normally nitrogen) filled in elastomer bladder. Due to the compressibility of inert gas, the accumulator enables to store, stock and return a liquid under pressure.
An accumulator enables a hydraulic system to cope with extremes of demand using a less powerful pump, to respond more quickly to a temporary demand, and to smooth out pulsations.
The accumulator comprises of a welded or forged pressure vessel, rubber bladder and valves at the gas and the fluid connection. Apart from the standard products, we also offer customized accumulators as per details of the clients.

Piston type Accumulator
We offer piston accumulator which consists of a fluid section and a gas section with the piston acting as the gas-tight separation element. The gas section is pre-charged with inert gas source (normally nitrogen) . The fluid section is connected to the hydraulic circuit so that the piston accumulator draws in fluid when the pressure increases and the gas is compressed. When the pressure drops, the compressed gas expands and forces the stored fluid into the circuit
Piston Accumulators can be availed in variable diameters and volumes. These accumulators can be offered with a piston position control system to enable you to have various switching functions in hydraulic systems.
