Pulsation Dampers Sizes - Packed Plunger Pumps / Connections / Part Numbers

Pulsation Damper Size Selection Tables for use in systems where flow is from Packed Plunger Pumps.
1. Dampers listed below are from 1000s of "off the shelf" inventory dampers, for preventing pipe systems from converting plunger flow fluctuation into pressure pulsation. Call toll free 1-888-DAMPERS (326-7377) for discounts, etc. Choose a damper matching your pump connection size, for standard damping. Or allow us to calculate for you, from your smoothness required and your system data.
2. The right bore improves pressure pulse damping and saves more pipe than damper costs. Where an area of 2 suits constant suction velocity, 6 suits peak velocity suction stabilizer to pump inlet. 3 suits pump outlet to discharge bottle and 1 suits constant discharge out of bottle.

INSTRUCTIONS:
4. Please choose the damper part number from the table , which has the same connection size as your pump.
5. We have made these "pre-engineered" selections for you, on the basis of 40 years experience, and average
application circumstances.
6. Please call us toll-free 1-888-DAMPERS (326-7377) with the part number chosen from the tabulation. We will then
find the current price for you.

Pulsation Damper with Liquid Elastomer Bladder - High PressureWith ELASTOMER BLADDER
No flow reversal pressure generation in a single connection. Perfect discharge acceleration head prevention, and pressure pulsation interception.
Pulsation Damper with Liquid Elastomer Bladder - Low Pressure
No flow reversal pressure loss in a single connection. Perfect suction acceleration head loss recovery.
Pulsation Damper with PTFE Membrane - High Pressure FlexOrber
With FLEXFLON or PTFE DIAPHRAGM. No flow reversal pressure generation in a single connection. Perfect discharge acceleration head prevention, and pressure pulsation interception.
Pulsation Damper with PTFE Membrane - Low Pressure FlexOrber
No flow reversal pressure loss in a single connection. Perfect suction acceleration head loss recovery.
The original "ELASTOMER GAS BAG" damper from its originators. For externally corrosive environments, economical high pressure capability by tall and slim, but sacrifices high frequency capability of the larger diameter true DAMPERS - the PipeHugger and the FlexOrber above.
Pulsation Dampers Installed Correctly Increase Performance



3. 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; use second connection to save a "T" for RV. PI, or System Drain. 2 connection dampers are standard lowest cost. WaveGuard and DAMPERS for 10Hz. & above, IE systems 300 meters (1000 ft.) or less, must use FLOW-THROUGH.

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