Why is a pressure gauge connected behind the pump
Thread Content
I would like to ask everyone: why is a pressure gauge usually connected to the back of a pump? Is it necessary to connect one to all pumps? Do pneumatic diaphragm pumps also require a pressure gauge?
The main purpose of connecting a pressure gauge behind the pump is to measure the outlet pressure of the pump, in order to ensure that its operating conditions meet the design requirements. For some process operations that require strict control of flow and pressure, this data is very important. Not all pumps require a pressure gauge; the decision depends on the type of pump and the application scenario. Some common pumps that require pressure gauges include centrifugal pumps, piston pumps, screw pumps, etc. Pneumatic diaphragm pumps can also be connected to pressure gauges, as their flow rate and pressure also need to be monitored and controlled. However, some pumps with low pressure and low flow rates may not require such a device; it depends on the actual circumstances. -
