    Positive displacement (PD) pumps contain an inlet valve that alternately opens and closes, creating an acceleration and deceleration of fluid into the pump. Depending on process fluid characteristics and pipe arrangement, there will either be a scarcity or abundance of pressure and/or flow at the pump's inlet. The SENTRY Inlet Stabilizer with the patented J-Model air control effectively works to minimize these pressure fluctuations and acceleration head losses by preventing fluid column separation at the pump's inlet.


    • Positive displacement pump discharge sizes from 1/8"" (3.18mm) to 6"" (152.4mm)
    • Temperature ranges from -60 F to +400 F (-51 C to + 204 C)
    • Custom models available up to 100 gallons (378.5L) & 25,000 psi (1,724 bar)
    • The patented ""J"" Model air control allows for pressure or vacuum settings and is adjustable for suction lift or positive inlet pump conditions. (US Patent 6,089,837)
    • SENTRY Pulsation Dampeners, Surge Suppressors and Inlet Stabilizers come in a full range of chemically resistant materials for even the most corrosive applications
    • NSF/ANSI 61, CE, ATEX and CRN certifications available on select models
    • All SENTRY housings are made in the USA, and each unit is tested at design pressure or higher to assure proper function and leak-free operation
