Pulse Dampeners Selection for Test / HP Injection Systems / Reciprocating Intensifiers

Pulsation Dampener Size Selection Tables for piping systems where the flow is from a test / injection pump.


Injection Pump


When you see a pulsation dampener or a pump of particular interest, please request literature dedicated to that subject. 1. Pulsation dampeners listed below are from 1000s of "off the shelf" inventory pulse dampers for preventing pipe systems from converting injection pump flow fluctuation into pressure pulsation. Call toll free 1-888-DAMPERS (326-7277) for discounts, etc. Choose a pulse damper matching your pump connection size, for standard dampening. Or allow us to calculate for you, from your smoothness required and your system data.
2. 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 dampeners are standard lowest cost. Decompression shot interceptors, & for frequencies above 10Hz. (from shortest pipes) must be FLOW-THROUGH


PipeGuard UHP & HP with Super Duplex and Duplex Stainless steel bodies. For Offshore and corrosive environment applications 100:1 Pumps
with Super Duplex (2507, UNS S32750) and Duplex Stainless steel (2205, F-51, UNS S31803) bodies. For Offshore and corrosive environment applications 100:1 Pumps


For use with 25:1 ratio pumps, flow smoothing PIPEGUARD MP to suit accumulator safety blocks.

Pulsation Dampeners - PipeGuard Low Pressure
Fill the fast return stroke, stops lost motion, so smooth the discharge.

FlexOrber HP with "FlexFlon" PTFE - For purity. For corrosive liquids. 40:1

with "FlexFlon" PTFE - For purity. For corrosive liquids. Prevents lost volume on the fast return / suction stroke; so stops discharge shock.
PipeHugger HP with an Elastomer Bladder. - Large diameter relative to port holes enables dissipation of the pressure wave from pump cylinder decompression. For 40:1 pumps

PulseGuard Pulsation Dampeners
Dampeners that do, flow goes through but pressure pulsation does not.

PulseGuard pulsation dampeners are designed to address pressure pulsation, which is caused by the resistance of the system to flow. Therefore our dampeners focus on the system related responsibility and are less related to pump liability.
