Hose Pumps Pulsation Dampeners / Flow Through / Sludge and Slurry
|
Ensure lowest in place cost and most performance by standard close coupling installation methods. Half the cost and triple the performance, of staying "pulse free" in hose pump systems. Dampening suction spike and discharge "back-flow" on hose pumps. The flow rate can not increase or decrease momentarily because the speed of rotation is constant. So the blip from the shoe or wheel mashing the hose, has to result in "back flow".

Liquid in Bladder Hose Pumps Dampener A flow through bladder type pulsation dampener that is smooth as a turbine and in place flush able.
Lined Liquid in Bladder Pulsation Dampener PipeHugger low pressure lined pulsation dampeners for liquid compatibility. Replaceable elastomer lining - Same material as bladder.
Plastic Pulsation Dampener PipeGuard plastic pulsation dampeners / accumulators for flow fluctuation only. Pressure waves will by-pass.
PTFE Diaphragm Dampener Flexorber LP is chosen where ease of flush through in place cleaning is enhanced by using DuPont Teflon or LDi FLEXFLON. And where the compatibility of PTFE diaphragms will increase life.
Flow Through Flex Tube Type Dampener Where you have 4 to 6 feet available directly on to the pump. An elastomeri c"hose" dampener for elastomeric hose pumps.
PumpGuard Pulsation Dampener Specification Pulsation dampener for systems containing high viscosity or sludge and slurry liquids
Pulsation Dampener Information for Other Pump Types
Centrifugal Pump Dampeners Centrifugal pump needs protection against pipe system frequency response & for start-up surge.
Gear Pump Dampeners Even these, THE SMOOTHEST of all POSITIVE DISPLACEMENT PUMPS have pressure disturbances, which are normally not important, but when they are connected to piping systems that were not designed, will cause pulsation.
Pulsation dampeners from 1000s of "off the shelf" inventory dampeners are available for preventing pipe systems from converting hose flow fluctuation into pressure pulsation. Call toll free 1-888-DAMPERS (326-7277) for more information. Where no OSHA requirement for in place flush before service, nor process need for 1st in 1st out, constant temperature, change of liquid pumped, interception of pressure pulsation; use second connection to save a "T" for RV. PI, or System Drain. 2 connection flow through pulsation dampeners are standard lowest cost.
Flow fluctuation on suction side is caused by when shoe hits hose, liquid goes backward up suction pipe. Flow fluctuation on discharge side is caused by when shoe lifts off, liquid rushes back to fill the void in the hose. The pipe turns the flow spikes into pressure spikes.
Find the "F" Value of Your Pump - "F" is a correction Factor on the square of number of displacers. Example, Centrifugal pumps are intrinsically good - have a high F, Sandwich diaphragm metering pumps have a low F. The F figure below assumes that the size of the shoe or wheel is approximately. one third of the volume between shoes or wheels. A hose pump squelches out 150 liters of effluent sludge per minute, with 3 shoes revolving 15 times per minute. 150 liter / 3 shoes x 15 revs = 3.33 liters between shoes.
F = 0.4 @ 0.75 Hz.
