Piston-Type Accumulators

An Overview

The variety and versatility of the piston-type design allows it to be utilized in over 90% of all potential applications. From a volume of a few cubic inches to hundreds of gallons, and up to 20,000 PSI MAWP, the piston-type hydro-pneumatic accumulator can meet the diverse needs of many industries with a standard or custom design.

Tobul has developed several distinct families of standard piston-type products, based on physical dimensions, MAWP (Maximum Allowable Working Pressure), and fluid volume. Each of the families is listed in this catalog and can be utilized as the basis for custom designs. Tobul piston-type product families are:

2000 PSI MAWP Series

“ECONOLATOR®” Series

3000 PSI MAWP Series

5000 PSI MAWP Series

10,000 PSI MAWP Series

Custom Design Series including “Big Bore®” Series

Tobul’s ability to provide a variety of raw materials, (carbon steel, stainless steel, and various alloys) seal configurations and compounds, (Buna-N, EPR, Viton, Kalrez, Teflon, etc.) fluid and gas port configurations, and design characteristics to best meet the needs of the end customer makes them “A Name for Excellence in Fluid Energy Control.”
