Positive Displacement (PD) pumps create pulsation and hydraulic shock due to the reciprocating nature of their stroking action, potentially damaging the entire pumping system. Pulsation Dampeners remove hydraulic shock and reduce the pressure and flow fluctuations. This enhances the all-around performance and reliability of fluid handling equipment in industrial, chemical transfer, and precision metering applications.

Increase productivity, safety, reliability and efficiency & Decrease maintenance and operating costs.

Datasheet PDF


How it Works

The nitrogen gas pre-charged bladder inside the Pulse-Stop dampens the pressure pulsations created by the reciprocating action of the pumps.

Application

FEC Pulsation Dampeners are specially designed for use with high pressure reciprocating piston and plunger pump systems.

BENEFITS

Increase pump efficiency
Reduction in pump downtime
Reduction in noise and vibration
Reduction in costly damage to the system components

Efficiency

A properly selected pulsation dampener installed at the discharge side of the pump can both reduce the dampening pulsations and enhance the pump’s efficiency and service life.

DESIGN & SIZE

Operating Pressure up to 3000 PSI
Replaceable Bladder (in minutes)

Constructed of carbon steel and internally coated to resist corrosion. The port assembly is of stainless steel 300 series construction.
