【Q&A Question 159】June 8, 2018: Briefly explain why pressure gauges are installed at the inlet and outlet of the pump A pressure gauge is a safety accessory that ensures smooth operation. By installing a pressure gauge at the pump inlet, it is possible to check whether the pressure at the pump inlet is higher than the vapor pressure of the liquid, thereby preventing the pump from running dry. Installing a pressure gauge at the pump outlet allows one to determine whether the pump is functioning properly and whether the pipelines downstream are unobstructed. In short, a pressure gauge at the pump outlet is an essential safety accessory for ensuring the pump operates smoothly. .

Assess the pump’s operating condition to check for issues such as vacuum formation or clogged filters
A pressure gauge is a component that helps ensure smooth operation; by installing a pressure gauge at the pump inlet, it is possible to check whether the pressure there is higher than the vapor pressure of the liquid, thereby preventing the pump from running dry. Install an outlet pressure gauge to check whether the pump is working properly and whether the pipelines at the back are unobstructed. In short, the pump outlet pressure gauge is an essential safety accessory to ensure the smooth operation of the pump.
The pressure at the pump outlet is an important indicator of the pump’s flow rate. The absence of pressure indicates that the pump is not delivering any flow. A drop in pressure suggests insufficient inlet flow, resulting in cavitation; this could be due to a clogged pump inlet filter, or blockages in the inlet pipes or the equipment upstream of the pump. Excessively high pressure is caused by high resistance in the outlet pipes, including blockages, high backpressure, or a faulty check valve.

Check whether the pump is operating normally
A pressure gauge is a safety accessory that ensures smooth operation. By installing a pressure gauge at the pump inlet, it is possible to check whether the pressure at the pump inlet is higher than the vapor pressure of the liquid, thereby preventing the pump from running dry.

Prevent the pump from failing to deliver flow by monitoring the outlet pressure in real time to control the outlet valve
