Pulsation Dampener part number that matches Lobe Pump

Lobe Pumps

by industry

1. dampeners listed below are from 1000s of "off the shelf" inventory dampeners , for preventing pipe systems from converting lobe flow "rumble" into pressure pulsation. Call toll free 1-888-DAMPERS (326-7277) for discounts, etc. Choose a dampener matching your pump connection size, for standard damping. Or allow us to calculate for you, from your smoothness required and your system data.

3. Before selection consider Pipe design can stop any dampener from performing. A small dampener piped well is far better than a huge dampener piped incorrectly.

Economical - Liquid in elastomer bag, Air in shell. Shorter In to Out dimension than PumpGuard. Higher performance.

with "FlexFlon" or PTFE for those aggressive liquids. Do not lose two thirds of the smoothness performance by being off line on a "T".

Where you have 4 to 6 feet available directly on to the pump. An elastomeric "hose" dampener for "ram thru" cleaning. No prefill required with PermaCushion and FlexTube support.

With the liquid inside the bladder every time it pulses, it shakes any particulate loose. This is the opposite of our PipeGuard or its copies. They pack the entrained material into a solid cake between the gas bag and vessel wall. Quick release 4 bolt dampener. Save a “T” and have 3 times the performance. The piping base is normally welded into the system to maintain as tested integrity during service. This also saves the cost of flanges.

"FlexFlon" and PTFE surfaces are easier to flush off high viscosity liquids. Mounting nuts in 3 places. Four bolts for quick dampener removal. Save a “T” and have 3 times the performance. The piping base is normally welded into the pipe to maintain system integrity.

PumpGuard - Where you have 4 to 6 feet available directly on to the pump. An elastomeric "hose" dampener for "ram thru" cleaning. No prefill required with PermaCushion and FlexTube support.

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.

4. 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, or preventing sedimentation; use second connection to save a "T" for RV. PI, or System Drain. 2 connection dampeners are standard lowest cost.

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.
