H2O Rx has introduced a range of high pressure pulsation dampeners manufactured by Blacoh Fluid Control. The Sentry XP pulsation dampener is specifically designed for heavy duty and high-pressure applications up to 275 Bar (4000psi).
Constructed to a 4 to 1 maximum allowable working pressure safety margin, the XP features a rugged shell construction machined from a solid rod of 316L or plated carbon steel, and is available in 8 to 24 cubic inch volumes.
The XP dampener also features a 6.9cm (2.75-inch) thick plug top held in place by two 2068 Bar (30,000psi) extra heavy-duty retaining rings designed to withstand shock loads four times the maximum working pressure.
Bladders are available in Buna-N, EPDM, and Viton, with other materials available on request.
For even more extreme applications, custom manufactured pulsation dampeners with up to 378L (100 gallons) capacities and for pressure ratings up to 1723 Bar (25,000psi) are available through H2O Rx.
Positive displacement (PD) pumps create pulsation and hydraulic shock due to the reciprocating nature of their stroking action, potentially damaging the entire pumping system.
Pulsation dampeners and surge suppressors manufactured by Blacoh remove virtually all hydraulic shock, enhancing all-around performance and reliability of fluid flow in industrial and chemical transfer applications.
