Description
G.P.T.CO Suction Side Manifold For 3 Pumps — Zinc Plated Steel
The G.P.T.CO three-pump suction manifold is the intake header for a triplex booster or pressure system. It divides a single supply line into three balanced pump inlets on one machined body, replacing the field-welded headers and stacked tee assemblies that create turbulence, trap air, and load the pumps unevenly.
The body is a one-piece zinc plated steel tube with male NPT threads at both ends, so it can be fed from either side or coupled in-line on larger skids. Three male NPT branch connections drop from the underside of the body at equal 12″ centers to meet the pump suction ports, and a 1/2″ NPT female sleeve near the inlet accepts a vacuum gauge, low-pressure cutoff switch, or drain.
