Sentry XP Series High Pressure Pulsation Dampeners

Innovations in Extreme Pulsation Dampening for Extreme Applications

Blacoh's Sentry XP Series high pressure pulsation dampeners in 316L stainless steel with pressure ranges up to 15,000 psi (1,034 bar) and optional pressure gauges are ideally suited for metering and dosing applications typical in the oil and gas industry. With excellent chemical and thermal resistance, our patented PTFE Bellows design offers excellent flex life, compatibility with virtually all chemicals and solvents, and can withstand temperatures up to 220°F (104°C).

Aggressive Fluid Handling

Also available with PTFE Bellows up to 5,000 PSI (345 bar). High pressure, highly aggressive fluid and high temperature? No problem. With excellent chemical and thermal resistance, Blacoh's patented PTFE bellows have an excellent flex life, are compatible with virtually all chemicals and solvents, and can withstand temperatures up to 220°F (104°C).

High-Frequency Dampening

Blacoh's newest SENTRY XPH high pressure stainless steel pulsation dampener with a flow-through inlet is specifically designed to remove high frequency pulses greater than 15 Hz.

The XPH dampener's unique design allows it to effectively remove both hydraulic pulses and acoustic pulses. Residual pulsations of less than 1% can be achieved with the flow-through design versus a single inlet/outlet dampener.

In high performance applications, where it is desirable to remove these pulses and obtain exceptionally smooth pressure and flow, an XPH series dampener is the preferred choice.
