pressure gauge on positive displacement pump
pressure gauge on positive displacement pump
(OP)
Hi All:
I am using a PDP drawing a liquid from a tank. The pump center line is located below the bottom of the tank and there is always some liquid in tank. The pump works fine and moves liquid to a certain height without any difficulty. This pump is has magnetic drive.
Problem: The pressure gauge on pump discharge shows ZERO psi.
Question:
1. Why it is showing zero reading even everything is OK?
thanks.

One problem is that if a guage is stripped, quite common on PDPs you will not see the increase. Usually a PDP gauge will be liquid filled and the desired pressure in the midrange.
If there is a possibility that the pressure tap is plugged don't do it.
Just be careful around the discharge of PDP, stop and think before each step.
