SENTRY™ Inlet Stabilizers

Stabilize Inlet Pressure and Flow.
Eliminate Acceleration Head Loss.
Extend Pump Diaphragm Life.

Designed to stabilize pressure and fluid flow on the inlet side of any pump, SENTRY Inlet Stabilizers, with our unique J Model air control, prevent water hammer and eliminate acceleration head loss to extend the service life of pump diaphragms and inlet system components.

Inlet Stabilizer Features

How It Works

The inlet valve on positive displacement pumps alternately opens and closes creating acceleration and deceleration of fluid flow to the pump, causing alternating drops in pressure and pressure spikes in the inlet piping.

Installed at the pump’s inlet, the Inlet Stabilizer acts as an accumulator to store fluid and release it back into the line as needed. Virtually all acceleration head loss is eliminated because the pump draws fluid from the dampener and not the pipeline, avoiding the risk of cavitation and ensuring complete chamber fill on each inlet stroke of the pump.

Benefits

Minimizes pressure fluctuations and prevents water hammer pressure spikes.

Eliminates acceleration head loss and cavitation.

Extends pump diaphragm life and protects system components from excess stress, vibration and fatigue.

Smoothes inlet fluid flow and ensures complete pump chamber fill.

Improves accuracy of inlet side gauges.
