Dare to take a leap into the 20th century - now we are in the 21st!
"A pinch of prevention, is worth a cart load of cure".
A. Prevent pump check valves from being driven by system pulsation response.
B. Prevent valves from "talking" to each other - let them close when they should.
C. Prevent interaction - intercept everything nasty between each cylinder and the system.

The principle is simple, it is at work every day under your hood
Gas flows more freely than liquid, yet reciprocating pumps have not made it any easier for a hundred years. The LDi "OctoPussy" doubles pump performance.

OctoPussy

Feed & exhaust the pump, without restriction

For single & simplex pump systems
Even a single suction or discharge pipe, benefits from flow-through interception.
Single Suction
DrawingFor welding into an 8" pipe with a 12" dampener connection split in 2 with port divider.
Standard PortingStandard porting for discharge

Intercepts everything.
Would you buy a single connection muffler or one port filter?

For two pumps or for duplex heads
