Pressure Pulsation Dampers Connection Options for Close Coupling

A SMALL DAMPER OF LARGE DIAMETER FITTED CLOSE TO A PUMP IS BETTER THAN A LARGE DAMPER OF SMALL DIAMETER FITTED AWAY FROM A PUMP KEEP THE DISTANCE FROM DAMPER INTERNALS TO PUMP INTERNALS LESS THAN 10 PIPE DIAMETERS.

or if you only require flow fluctuation reduction, with no guarantee of pressure pulsation damping, then
USE THE EXTRA CONNECTION TO SAVE A "T" FOR THE SYSTEM RV, DRAIN, or GAUGE.

STANDARDS FOR MULTIPLE & MULTIHEAD PUMPS

DISCHARGE SUCTION

In multi pump, & multi head, systems: Pressure pulsation reduction level can be guaranteed by preventing interaction between pump head check valves, and preventing resonance

PIPING BASES part number MG/

SIMP-X = For 1 pump head. DUP-X = For 2 pumps or 2 individual pump heads.
TRI-X = For the confluence 3 pumps or 3 individual pump heads. QIN-X = For 5 pumps or heads.
All -- X designations prevent individual pump and valve activities from the system responses "talking to each other".

Close coupling ensure that the small mass of the liquid column is unable to excite the pump parts by going into oscillation. True thru-flow ensures that pressure fluctuations are captured and can not by-pass. Alternately liquid mass that has to go up one hole, come to a halt, then reverse back out again in a fraction of a second, requires huge pressure fluctuations to produce this instantaneous mass reversal.
