Surge Suppressors:
SENTRY Surge Suppressors use a compressed gas separated by a bladder from process fluid to suppress hydraulic surge or water hammer  
created by quick-closing valves, back surge, and pump start-up/shut- down.  Without suppression, shock waves created will continue to oscillate back and forth until dissipated by friction or system component failure.

Diaphragm Seals:
Sentinel diaphragm seals employ a chemically resistant diaphragm to effectively isolate process fluids from recording gauges and other process instrumentation.  This durable diaphragm allows Sentinel to accurately transfer process pressure without direct contact with hazardous or corrosive fluids.

Pulsation Dampener:
SENTRY Pulsation Dampeners use a compressed gas separated by a bladder from the process fluid like a shock absorber.  During the pumps discharge stroke, fluid pressure displaces the bladder, compressing the trapped gas.  During the pumps next cycle, fluid 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 the cycle shift and dampens pulsation up to 99%.

Inlet Stabilizer:
The patented J Model Inlet Stabilizer accumulates liquid at the pumps inlet to improve the flow conditions to any pump.  This insures complete chamber fill and extends the serivce life of all inlet system components.  The J Model inlet stabilizer features a patented control that allows you to adjust for pressure or vacuum depending on whether pump operation is under suction lift or positive inlet conditions.  Patent # 6,089,837.

Leak Containment:
The SPILLSTOP attaches directly to the exhaust of an air operated diaphragm pump.  Upon diaphragm failure, the Spill-STOP prevents spills by capturing contaminated or dangerous liguid in a internal receptacle while raising a float switch.  This switch automatically turns off the pump pneumatically and, for most applications, is configured to sound a warning alarm and/or initiate a backup pump switchover.
