Tobul Accumulator has developed several distinct families of standard piston-type products, based on physical dimensions, MAWP (Maximum Allowable Working Pressure), and fluid volumes. Tobul accumulators can be adapted with, a variety of raw materials (carbon steel, stainless steel and special alloys), seal configurations and compounds (Buna-N, EPR, Viton, Kalrez, Teflon, etc.), and fluid and gas port configurations, to suit individual applications.
Tobul’s piston accumulators are designed with multiple sizes from 2.375 to 24 in. (60 to 603 mm) diameter, 0.063 to 200 gallons (0.24 to 757 liters), and 2,500 to 10,000 PSI (172 to 690 bar) MAWP. The variety and versatility of the piston-type design allows it to be used in more than 90% of all potential applications, enabling the piston-type hydro-pneumatic accumulators to meet the diverse needs of many industrial and mobile applications. Its inherent design features also eliminate catastrophic failures.
