Pulsation Dampeners for Screw Pumps

Screw pump piping system pulsation dampening. Curing the kick in screw pump pipe systems with the PumpGuard pulse dampener.

Because flow is so slow, there is time to flow up, come to a stop, and flow back down a “T” – on the other hand, whatever the residual pressure pulsation level is, it will still shake the pipes.

Volume accumulator only is bigger, better, or “bonkers”?
The tide ebbs & flows slowly. But the impact from the velocity of waves does the damage fast.
Mass of liquid in a pipe is transferred at not above 180 inches/sec or say 460 cm/sec. Pressure in a fluid travels at mach 1 (in air), in harder substances (liquid) is transferred at up to 4000 MPH, or say 140,000 cm/sec.

CONCLUSION:- Damping "non Newtonian liquids" requires designs that do not pack cake and trap material against the vessel wall. Constant agitation 1st in 1st out is a clear advantage. No flow reversal in a single opening enables max smoothness. Only flow through dampeners suit screw & worm systems.

A pulsation dampener intercepts pressure pulsation and smoothes flow fluctuations, is smaller and costs less to install.

ISO 9001 registered by DNV QA in 1995.
Dampeners produced in NC USA, are to our design code (in excess of ASME VIII which states non- applicability to dampeners) or they may be “U” stamped at extra costs but have all warranty removed.

Pulsation Dampener Selection for Screw Pumps

Removing the "kick" from screw and "worm" pump piping systems.

Your pump connections suit its flow, and its fluctuations are related to the pump type, so the dampeners have been pre-selected for you. Simply choose the dampener that matches your connection size. Or call us, with your RPM, flow rate, and required smoothness, so that we can make a specific selection for you.
