Minimizing Residual Pulsation by Proper Dampener Installment

CONNECTION OPTIONS, For "Close Coupling" A small dampener of large diameter fitted close to a pump is better than a large dampener of small diameter fitted away from a pump. Keep the distance from dampener internals to pump internals less than 10 pipe diameters.

Standard for offshore platform injection systems - Twin – Cone 45 + West + South - Vibration proof autoclave, PPI

Standard for SoG & PeG units for low pressure & thin-wall pulsation dampeners. Aka "New England Style" - one up, and one in left field. One connection small for constant velocity to system and the other large for peak velocity from pump

"Dampeners that do - flow goes through, pressure pulses do not"
2 connection (minimum) for in place flushing before service. 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.

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

MeterGuard Piping Bases 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 ensures 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.
