EXTREME PULSATION DAMPENING

  • Compatible with virtually all chemicals and solvents.
  • Able to withstand high temperature applications.
  • Corrosion resistant 316L stainless steel solid shell housings with zero clearance ACME threaded caps.
  • Wide range of volumes, sizes, and inlet types for a variety of high pressure applications.
  • Cost effective construction to keep costs low when expensive alloys are required.
  • Ideally suited for metering and dosing applications typical in oil and gas industry.
  • Exclusive flow-through inlet design removes both hydraulic and acoustic pulses for exceptionally smooth pressure and flow; residual pulsation reduced to <1%.
  • Proudly made in the USA.

FLOW THROUGH MODEL

The SENTRY XPH Flow Through models are engineered to remove high frequency pulses greater than 15 Hz, as well as low frequency pulses. This unique flow through design allows the XPH model to effectively remove both hydraulic pulses and acoustic pulses for exceptionally smooth pressure and flow. With a properly sized XPH dampener, residual pulsation of less than 1% can be achieved.
