Pulsation Analysis, Diagnostics, Prediction by Software
a.k.a. "LDi" have specialized in designing "fancy plumbing" since 1975, and since opening our pipe fabrication shop in 1983, we have manufactured hundreds of these "OctoPussy" piping bases for Duplex, Triplex, Quad- and Quintuplex reciprocating pumps of many types, of numerous manufactures.

 For triplex heads, or for three pump discharge systems.
"Turbo" your triplex, with Octopussy - pipe system design detail.
Triplex Octopussy
3 Port
How 4 paths are divided in one mating face.
The conical OctoPussy piping confluence base block is machined then "ported" (flow contoured). Then a 2, 3, 4 or 5 port divider is inserted and welded in place.
On discharge systems, the sudden change from within the divider, to entering a large diameter dampener liquid chamber, explodes high frequency pressure transients which then die away exponentially with distance, to the nearest point of reflection.
For triplex head systems, or for three pump, suction systems.
And for the suction where it is most important.
Horizontal Connections
Space Saver
space saver; pump so low, it looses more from tight "Ls" than head gain
For quadruplex heads, or for four pump systems.
A quad pump needs OctoPussy more - even numbers are more likely to resonate.
Four Flow Paths
What Not To Do

Four flow paths curve up the central cone, in Coaxial outlet. Extends up into the mouth of dampeners from most manufacturers.

A four meter leg, a 2.5 meter leg, and a one meter legged OctoPussy. Sometimes it seems the engineering contractors conspire to defeat the object - which is in part close proximity.
