These accumulators are designed to store a small supply of pressurized oil, making them ideal for palletized machining workholding systems or any other system where supply pressure is disconnected temporarily. They are nitrogen charged, piston type accumulators allowing them to be mounted in any orientation. This type of accumulator has a wider operating range at any one charge pressure than any other type of accumulator. Depending on the application, they can be used at any pressure from 0-5,000 psi. Charge pressure is factory set at 1,500 psi and can be increased up to 2,000 psi. In general, a lower charge pressure will provide more total oil but a higher charge pressure will give more usable oil at a given allowable pressure drop. Refer to the performance charts to determine the best charge pressure for each application.
Accumulators come in two sizes (2 & 5 cu. in.) and are available in conventional mount and the newly introduced manifold mount.
