Pulsation Dampener part number that matches LP Dosing Pump

1. Pulsation dampeners listed below are from 1000s of "off the shelf" inventory pulse dampers for preventing pipe systems from converting LP dosing 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. It is least expensive to use standard twin connection dampeners, save a "T" - use the other connection for the system drain, RV or gauge when not flowing through.

All Stainless Steel , With "Flexflon" PTFE
For LP Dosing Pump discharge, & suction of HP pumps where EPDM, Buna N, Hypalon, Fluoros, are NOT compatible. Twin connections are off the shelf inventory items. If you do not wish to intercept pressure pulsation, nor to flush before service, save the cost of an extra "T" and use the second connection for your RV. PI, or System Drain. For high pressure see PipeHugger HP.

Liquid in elastomer bladder , 316ss etc. wetted.
For LP Dosing discharge & suction of HP pumps where EPDM, Buna N, Hypalon, and Fluoros are NOT compatible. Twin connections are off the shelf inventory items. If you do not wish to intercept pressure pulsation, nor flush before service, save the cost of an extra "T" and use the second connection for your R.V., drain, or gauge. For high pressure see PipeHugger HP.

elastomer lining same grade as bladder + special metal connection

peg plastic = pp pvc etc connection 250 psi maximum

has both flange rf and f npt + the strength of metal with the compatibility of plastic

Gas in elastomer Bag Liquid in 316ss shell
The 1965 Original, no popper, one piece molded - no glue or bong in the bladder (gas bag) , pulsation interceptor. If you do not want in place flusability, or to intercept pressure spikes. Then save a "T" and use the second connection for your RV, Drain or a PI.

Gas in elastomer Bag Liquid in plastic body
The 1965 Original, no popper, one piece molded - no glue or bong in the bladder (gas bag) , pulsation interceptor. If you do not want in place flusability, or to intercept pressure spikes. Then save a "T" and use the second connection for your RV, Drain or a PI.

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.

FlexOrber low pressure Pulsation Dampeners with capacitance + direction change impedance With pin type nitrogen pre-fill valve

with pin type nitrogen n2 pre-fill valve

$For externally corrosive use where danger of cold brittle fracture of plastics or softening due to high temperature is not acceptable.$

Any of the sizes listed are available in other plastics but not from off the shelf inventory. There are many other sizes.

The ratio of cross sectional areas inside the pipes for best pressure stability is 2:6:3:1. Where 2 is a suitable area for constant velocity suction supply, an area of 6 accommodates the peak velocity of the suction stroke. 3 will take the peak velocity of the discharge stroke, 1 will be ideal for the discharge.

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.
