BOLENZ & SCHÄFER accumulator systems are manufactured for the European market and are approved in accordance with the Pressure Equipment Directive PED 97/23/EC applicable as from 29.11.1999 and binding since 30.05.2002. This is applicable to the KAK and AK series piston accumulators.
BSD piston accumulators are suitable for storing hydraulic energy, absorbing pressure shocks, pulsation damping and compensating for flow fluctuation through compression of nitrogen.
Temperature range:
Temperature range standard -10° C to +80° C, different temperature ranges, e.g. -40° C to +80° C on request.
Condition on delivery:
Base-coated with universal priming color RAL 1001 (beige) inside and connecting surface oiled and openings protected, without hydraulic fluids, without gas filling.
Design pressure:
The design pressure corresponds with the max. allowable working pressure (MAWP) and is also the max. permissible set pressure for the safety equipment (safety valves, burst-discs) against pressure
excess. We recommend operation of the accumulators with a maximum pressure of up to 0.9 x MAWP to avoid safety equipment repetitive response.
- Optimal application solution derived by changing diameter or length
- Piston position monitoring possible
- Installation position arbitrary
- Total discharge is possible
- Long life, reduced friction sealing system
