PDF PG7 Gear Pulsation Damper Installation

Pulsation Dampers - Gear Pumps - Standard Installations

How to ensure lowest in place cost and most performance by standard installation methods.

Removing the ripple from gear pump piping
1. How it starts 2. A partial fix. 3. True solution - with elastomers
4. With PTFE/or "Flexflon" 5. No particulate 6. With dirt 7. Big but best.
Even these, THE SMOOTHEST of all POSITIVE DISPLACEMENT PUMPS have pressure disturbances, which are normally not important, but when they are connected to piping systems that were not designed, will cause pulsation.

INSTRUCTIONS:

2. Please move your mouse over the pump that has your choice of damper type attached to it. 3. When you click on that picture, of materials or damper type, a table of those damper types will appear.

	High frequency pressure pulsation is dissipated by wide ratio of hole size through which it enters to diameter of chamber. FOR A PARTIAL FIX when stainless and an elastomer are compatible GO TO:- price list of off the shelf inventory dampers, with dims. weights.
and from hydroformed dishings, with "Flexflon", PTFE, EIDP Teflon®, etc, have the largest chamber diameter to port hole ratio - combine best HF pulse interception with flow velocity smoothing. GO TO:- price lists of off the shelf inventory pulse dampers for dims weights and cut sheet drawing.
Pulsation dampers with no moving parts, and no foam to degrade or clog. "Maintenance free dampers" An admission that pulsation is acoustic not volumetric.

PUMPS make FLOW, SYSTEMS cause PRESSURE, pressure pulsation is a system response, AND a system responsibility NOT a pump manufacturers liability.
