Pulsation Dampener part number that matches Screw Pump

1. Pulsation dampeners listed below are from 1000s of "off the shelf" inventory pulse dampers for preventing pipe systems from converting screw 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. Waveguard and dampeners for 10Hz. & above, IE systems 300 meters (1,000ft.) or less, must use FLOW-THROUGH

Your pump connections suit its flow, and its fluctuations are related to the pump type, so the DAMPENERS HAVE BEEN PRE-SELECTED for you. Simply choose the dampener that matches your connection size. Or call us, with your RPM, flow rate, and required smoothness, so that we can make a specific selection for you.

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.

Prevents “suck down”. PermaCushion requires no prefill air. For suction and low pressure discharge applications. Typical configuration for an ANSI B16.5 or DIN flanged suction piping. With perforated FlexTube support for higher pre-fill pressure applications.

dampener for higher pre-fill applications with perforated flex tube support.

typical pulsation dampener for a high pressure discharge food or beverage application.

Where there is no occupational health and safety need for in place flush through before servicing, nor any process requirement for constant temperature, or first in first out need to control residence time, not even clean before changing liquids it is still least expensive to use a standard twin connection dampener , & save a "T". Use the other connection for the system drain, relief valve, or branch line. Waveguard and dampeners for frequencies above 10Hz., systems shorter than 300 meters to 1000ft. must use the FLOW-THROUGH feature.

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.
