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

Pulsation Dampeners Sizing Guide
The following formula sizes Pulsation Dampeners for use on diaphragm, piston and plunger type metering pumps.
Required Sizing Information:
V = volume per pump stroke in cubic inches
K = type of pump (K factor)
P = mean operating pressure
D = allowable pressure fluctuation as a percentage ( +/- from mean)
n = exponent for type of gas used (Nitrogen = 0.714; Air = 1.0)
V - Volume per stroke calculations:
| 1)
|
Gallons per minute / strokes per minute = gallons per stroke
Gallons per stroke X 231 cubic inches per gallon = cubic inch per stroke or |
| 2) |
.7854 X (inch bore diameter)2 X inch stroke length = cubic inch per stroke |
K - Type of pump:

.15 |
| Triplex |

P - Operating Pressure (Mean):
Allowable pressure fluctuations:
Minimum pressure Pmin = P - (P X D)
Maximum pressure Pmax = P + (P X D)
| Formula |
V x K ( P / Pmin )
1 - (P / Pmax) |
= Cubic inch capacity required |
