Uniform application when spraying and
metering
Blacoh Sentry Pulsation Dampeners applied to PD pumps remove virtually all system shock, enhancing all-around performance, safety, reliability, and consistency in spray and metering applications
Positive displacement pumps create a pulsating flow and hydraulic shock due to the reciprocating nature of their stroking action This pulsation makes the uniform application of product in spray and metering applications extremely difficult and can potentially damage the entire pumping system

Blacoh Sentry Pulsation Dampeners remove virtually all system shock, enhancing all-around performance, safety, reliability, and uniformity of fluid flow in spray and metering applications.
Sentry Pulsation Dampeners use a compressed gas separated by a bladder from the process fluid like a shock absorber.
During the pump's discharge stroke, fluid pressure displaces the bladder, compressing the trapped gas.
During the next cycle, fluid flow stops momentarily causing expansion of the compressed gas, forcing the bladder to push accumulated fluid back into the discharge line.
This fills the void created by cycle shift, dampening pulsation up to 99% and creating a steady, continuous, and uniform flow.
Sentry also ensures the accuracy, longevity, and repeatability of on-line meters and effectively reduces product agitation, foaming, splashing and product degradation.
Sentry bodies and bladders are available in a full range of chemically resistant materials for virtually all Positive Displacement pumps with discharge sizes from 1/8" to 6".
Models from stock offer pressure ranges up to 4000 PSI and with capacities up to 10 gallons.
Custom models are available up to 100 gallons and 25,000 PSI.
