Lobe Pump Pulsation Dampener Standard Installations

How to ensure lowest in place cost and most performance by standard installation methods. Low pressure medium frequency Lobe pump pipes CAN need pulsation dampening. Running on viscous liquids, a pulsation occurs.

The source of the disturbances: Magnified into pulsation by poor, no pipe design frequency analysis is from "X"

so finely that each makes a squirt from the valley between the lobes. The squirt may be measured as a "soft" shock.
2. GO TO:- PipeHugger LP & HP which provides both flow fluctuation smoothing, and the interception of pressure pulsation for both liquids and slurries. See PHr LP & PHr HP price lists for off the shelf inventory dampeners, dimensions, weights, and cut sheet drawing. Liquid in a bladder of EP, Buna N, Fluoro or Hypalon elastomer.
3. GO TO:- FlexOrber LP which provides smooth face virgin DuPont Teflon with flow through in place flushability. For inventory see price list and for dimensions, weight and drawing. Prefill valve open and close with a 3/4" wrench only. Alternates are VTFE elastomer backed encapsulated stiffener with virgin PTFE smooth face for clean in place or MTFE with 2 layers of modified PTFE diaphragms for toxins, pyroforic, and permeate service. Optional secondary containment sealing. For systems up to 4” tube that need DuPont Teflon or LDi “FlexFlon”.
4. GO TO:- WaveGuard where pressure pulsation is the issue, not flow fluctuation, WaveGuard's with no moving parts are the choice
WaG-HO with orifices for clean systems, WaG-MT that are much larger for dirty flow, WaG-Cer for smoothest with ceramic balls for wave breaking.

Carry a complete spare when service down time is important. No Nitrogen prefill required. PermaCushion foam fill and FlexTube elastomer from EPDM, Nitrile, Hypalon, Fluoro material. For prices, dimensions, weights, and section drawing of short lead time items, please see PuG price list.5. GO TO:- PumpGuard for high viscosity systems plus, slurries, foods, beverages. Good for suction

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.
