Oil Flow Through a Triplex Pump
Oil Flow Through a Triplex Pump
(OP)
I need help to calculate oil flow rate on lube system on a triplex pump. I have a 1" input lube manifold that is 3.5 ft long. On One side is the input and the other side is plugged.
Three, 1/4 " dia, 1 ft long hoses are connected (90 degree to manifold)to the lube manifold at 10 inches away from each other.
Two,1/2 " dia 2 ft long hoses are connected at each end (same as above), one after the input and one at the other end just before the plugged end is.
I do know the manufacturers has told me, the gear pump used to pump oil to the plunger pump is a 35 gpm pump. Manufacturer recommends to use( SAE 220 90 wt Gear oil), the system should maintain a pressure of 70-100 psi in the system.

This assumes no internal leakage and no loss through a pressure control valve(relief valve)or directional control valve.

It would make sense that if you provide lube delivery per the pump manufacturer's requirements, there will be sufficient lube flow to the triplex lube points. No need to spend time calculating the detail flows in the lube system.
