Pulsation Dampeners ACCU-PULSE
Developed to remove pulsating flows from positive displacement pumps.

  • Pulsation Dampeners,ACCU-PULSE,Pulsation,Dampeners,ACCU,PULSE increase system efficiency and pump life

  • decrease maintenance and costs

  • protect pipes, meters, valves and instrumentation from pulsation and vibration

  • ensure meter accuracy, longevity and repeatability

  • reduce pressure fluctuations and diaphragm wear

  • prevent foaming and splashing

Note: CRN is available on certain Accu-Pulse Dampeners. Please contact factory for price and availability.

General Sizing Guide

(Detailed Sizing Guide For Accu-Pulse Pulsation Dampeners)

Standard Simplex Metering Pumps:

The following are general ranges for sizing ACCU-Pulse Pulsation dampeners for metering pump applications.
Models stated are based on 10% pressure fluctuations and a Simplex single acting metering pump. For 5% pressure fluctuation, divide the Capacity per Stroke Range numbers in the chart below by 2.

To calculate cubic inches per stroke:

gallons per minute = gallons per stroke
strokes per minute
Gallons per stroke X 231 cubic inches per gallon = cubic inch per stroke

EXAMPLE:
.15 = .0015 GPS
THEREFORE:
.0015 X 231
= 0.3465 cubic inches per stroke
  100     = API Dome Top

For other pump factors, or residual pulsation, contact factory.

Air Operated Double Diaphragm Pumps:

The following chart shows the pulsation dampener and inlet stabilizer models for use on Air Operated Double Diaphragm (AODD) pumps.

The models stated will produce a flow up to 92% pulsation free. If a higher level of dampening is desired, the next larger capacity should be chosen.

The same models are required for both pump inlet stabilization and discharge pulsation dampening. Pricing pages listed are for standard plastic and metal models. Other models include: Teflon, food grade and sanitary.
