Bladder Accumulator

Bladder type Hydraulic Accumulator is an energy storage device which is mainly used during instant high demand requirement of hydraulic flow and pressure. It compensates pressure when there is a power outage or during switchover between pumps, manage the minor leakages and pressure drop takes place in the Hydraulic pipelines, fittings, and tubing, etc., It also acts as a shock absorber.

“Top repairable design” accumulator makes it possible to inspect the inside and replace bladders without having to remove them from piping. This type of Accumulator will greatly reduce the maintenance time and the cost involved.

“Welded type” bladder Accumulator is used mainly in low-pressure applications. The accumulator is fabricated with pipe and dish ends instead of seamless forming. The openings for the gas and fluid ends are precisely machined with high-precision CNC machines. Welding quality is validated using Radiography inspection to maintain the quality and integrity. The volumes are available in various ranges to meet the wide range of applications. The welded accumulators are available in Stainless steel material of any grade as well as in carbon steel material.

Features

  •  Standard as well as customized design to suit customer requirements.
  • Designed in accordance Pressure Vessel and Boiler Code Section ASME VIII Division 1 (with or without U stamp) and also available in other standards like BSEN 14359:2007 (with or without PED).
  • Seamless as well as fabricated shell design for wide range of design pressures.
  • Multiple options for process connection / gas connections to meet customer requirements.
  • The top repairable type does not disperse the hydraulic fluid during the maintenance, which is good for the environment.
  • The Universal Charging kit comprises of suitable pressure gauge, adaptors, and spare seals wrapped within a carrying case.
