Pulsation Dampers Sizes - Centrifugal Pumps / Connections / Part Numbers

	FOR ADDRESSING RESONANCE, CONTINUOUS HYDRAULICALLY INDUCED VIBRATION, IN CENTRIFUGAL PUMP PIPING SYSTEMS Pulsation Damper Size Selection Tables for pipe systems with Centrifugal pumps
1. Centrifugal system piping RESONANCE preventers below are from "off the shelf" inventory. Be sure to ring Free Phone/call Toll free for the current escalation and discount %ages. The size volumes listed have been preselected to suit your pump connection norms, simply choose the type that is from your material of choice, with the connection that matches your pump; this will provide standard damping. Or call us to make the selection.
2. Where there is no occupational health and safety need for in place flush through before servicing, nor any process requirement for constant temperature, or first in first out need to control residence time, not even clean before changing liquids it is still least expensive to use a standard twin connection damper, & save a "T". Use the other connection for the system drain, relief valve, or branch line. Waveguard and DAMPERS for frequencies above 10Hz., systems shorter than 300 meters or 1000ft, must use FLOW-THRU. Dampers.

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.

CERAMIC BALLS
Standing wave dissipation dispersal through a miriad of different length of flow path
The "e" number is use in computing the reduction in system acoustic frequency due to increased "softness"

& ORIFICE TECHNIQUES
Intercepts pressure wave pulsation back from the pipe system nodal lengths, and prevents them from feeding back to the pump impellers
The "e" number is use in computing the reduction in system acoustic frequency due to increased "softness".

For BACK-FLOW SLAM BUBBLE CATCHER
Causes the generation of a bubble cushion chamber. The cushion softens the backflow slam from the implosion of the cavity drawn out by the flow away from the pump on shut down.
The "e" number is use in computing the reduction in system acoustic frequency due to increased "softness".

"Capacitance + direction change Impedance"

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