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

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

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.

Fill the fast return stroke, stops lost motion, so smooth the discharge.

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.

with an Elastomer Bladder. - Large diameter relative to port holes enables dissipation of the pressure wave from pump cylinder decompression. For 40:1 pumps

Large Diameter Bladder ensures sensitive response at low pressure. Prevents lost volume on the fast return / suction stoke; so stops discharge shock

3. *The question mark “?” = letters, showing your choice of compatible gasket material, add the letter to ordering part number – N= Buna N, E= EP, (H= Hypalon, V= FluoroCarbon, additional cost) A20= Alloy20, H22= Hastrelloy22, Ti2= Titanium 2, Tan= Tantalum, Zir= Zirconium, DSS= duplex stainless steel, SDSS= super duplex stainless steel.

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.
