Light Weight Piston Type Accumulators

PistoLite Piston Type Accumulators

MagdAcc Piston Type Accumulators

A PistoLite accumulator has a light weight piston where the dynamic seals are aligned with the solid piston center, and where the both gas and liquid skirt ends have graphite filled Teflon guide rings.

HydroTrole piston accumulators have a sealing geometry that ensures pre-charge gas retention with immeasurable loss over an MTBF (meantime between failure) design criteria of 32 million cycles, with minimum hysteresis break out stiction achieved by placing the dynamic seals so closely adjacent each other that seal deflection ensures that the lubricant held between the seals instantly reaches the same pressure as the oil and the pre-charge gas. All pistons with so lightly loaded dynamic seals are prevented from experiencing a differential pressure at gas end and at liquid end of stroke by a static encapsulated shut-down seal than face seals against the end of the piston skirt on each side. Piston accumulators are recommended because when they do begin to go down it is gradual progressive, and determinate. They are recommended for emergency standby power.

Main Features: Solid Light-Weight Piston, Close-Coupled Seals, Dual Graphite-Filled Bearing Strips for Low Stiction, Various Seal Elastomers, Zero Leakage When Shut Down, Super Fast R Locking, Flow-Thru Port Facility.

Pistolite Piston Accumulator Applications

Application(s) or example(s) that save peak hydraulic horsepower energy levels and reduce capital costs for pumping systems, whilst increasing control precision.

PistoLite applications- the economy safety responsiveness of the PistoLite accumulator range has resulted in its ideal use for many applications. the high flow rate part of injection molding and die casting hydraulic systems is perfectly addressed with PistoLite accumulators generally connected to additional gas volumes a.k.a. back up bottles, the combination of which results in large volume supply with small pressure fall and a pump investment only 1/3 of what would otherwise be applicable. Similarly in the pressings industries they are used for ring mains and normally reside in the pump house. Most efficiently multiple fixed displacement pumps are used by deploying IndAcc or MagdAcc control (see IndAcc).
