Positive displacement pumps create destructive pulsation and hydraulic shock due to the reciprocating nature of their stroking action, potentially damaging piping and system components. SENTRY Pulsation Dampeners and Surge Suppressors remove virtually all system shock, enhancing the performance and reliability of fluid flow in municipal, industrial, sanitary and chemical transfer applications. SENTRY Inlet Stabilizers minimize pressure fluctuations and acceleration head losses by preventing fluid column separation at the pump's inlet.
Features:
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)
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.

SENTRY XP dampeners in 316L Stainless Steel with pressure ratings to 15,000 psi (1,034 bar) and optional pressure gauge are ideally suited for metering and dosing applications typical in the oil and gas industry. PTFE bellows are available 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 220ºF (104ºC). Pressure rating to 5,000 psi (345 bar). Our newest XPH dampeners with a flow-through design are specifically designed to remove high frequency pulses greater than 15 Hz in addition to low frequency pulses. Removes hydraulic and acoustic pulses.
Designed for chemical processing, water treatment, and food/beverage applications, the Blacoh sanitary line of dampeners and surge suppressors feature specialized stainless steel bodies and tri-clamp fittings. For hygienic applications requiring clean-in-place components, the SENTRY CIP in-line flow through design and unique patent pending tube bladder eliminate problems with product holdup and trapped particles. Ideally suited for handling slurries and viscous fluids, it's gentle enough for the most delicate products.
