Pulsation Dampeners Installation for Screw Pumps

Pulsation Dampeners for Screw Pumps Selecting Dampeners for use in Viscous and Sludge Systems

Pulsation Dampeners for Screw Pumps Removing the "Kick" from srew and "worm" pump piping systems With the PumpGuard Pulse damper Prevent "Suck Down" Perma Cushion Perma Cushion Requires No Pre Fill Air For suction and low pressure discharge applications Typical configuration for ANSI B16.5 or DIN flanged suction piping

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

Pulsation Dampeners - Flow and PressurePulsation Dampeners - Flow and PressurePulsation Dampeners - Flow and Pressure

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.

Pulsation Dampeners InfoPulsation Dampeners Info

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.

Select fluid control pulsation dampeners for your system only after you know how to connect them
When you see pulsation dampeners, reciprocating pumps, rotary pump, or other hardware type of interest, request literature dedicated to that dampening subject ( 1-888-DAMPERS )

Pulsation dampeners are designed to address pressure pulsation, which is caused by the resistance of the system to flow. Therefore, our pulsation dampeners focus on the system related responsibility and are less related to pump liability.
PUMPS make FLOW, SYSTEMS cause PRESSURE, pressure pulsation is a system response, AND a system responsibility NOT a pump manufacturers liability.
