Pulsation
Dampeners ACCU-PULSE
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

Sizing
Guide
The following formula
sizes are 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 |

P
- Operating Pressure (Mean):
Allowable pressure fluctuations:
Minimum pressure Pmin = P - (P X D)
Maximum pressure Pmax = P + (P X D)
