with Various PULSEGUARD Dampers

Low pressure medium frequency Lobe pump pipes Can need pulsation dampening -
Running on viscous liquids, a pulsation occurs.

Recommended Comparisons, To COSTS of Lobe Pumps with Pulsation Dampers

(1) The source of the disturbances:
Magnified into pulsation by poor, or no pipe design frequency analysis is from "X"
Lobes nest into each other
lobe pump detail
so finely that each makes a squirt from the valley between the lobes. The lobes 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 dampers, dimensions, weight and cut sheet drawing.

Liquid in bladder of EP, Buna N. Fluoro. or Hypalon Elastomer.
(5) GO TO:- PUMPGUARD For high viscosity systems plus, slurries, foods & beverages.
Good for suction systems and discharge to 100 psi, where cost is not the major consideration.
Carry a complete spare when service down time is important.

Where pressure pulsation is the issue, not flow fluctuation, WAVEGUARDS with no moving parts are the choice.

Selecting Pulsation Dampeners for Different Pump Systems.
Flow through pulsation dampers are at least 3 times more efficient than T off line accumulators.
Dampeners that do, flow goes through, but pressure pulsation does not.
