Pulsation Dampers Sizes - Multiplex Power Pumps / Connections / Part Numbers

	Pulsation Damper Size Selection Tables for use with Multiplex "Power Pumps"
1. Dampers listed below are from 1000s of "off the shelf" inventory dampers. 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. 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., and or systems in which pipe-run or tube nodes are less than 290 meters /950ft have to be "Flow-Through"

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