When using chemical pumps, many users inevitably encounter situations where the head pressure is insufficient or there is a lack of fluid in the pipeline. Today, the editor will explain to you the reasons why the head pressure of chemical pumps is too low and how to address this issue. 1. Check whether the discharge pipeline of the pump has too low resistance. 2. Verify if the outlet pressure is too low and the reference suction height is too high. 3. Check for any leaks in the suction pipeline. 4. Examine the pump’s speed to ensure it isn’t too low. 5. It’s also possible that the viscosity of the liquid being pumped is too high or its density is too great. 6. Check if there is an issue with the pump’s rotation direction. The above are some of the more common problems that can occur when the head output of a chemical pump fails to meet the standards. Next, I will explain to you what to do when a chemical pump fails to achieve the required head pressure ; 1. Adjust the control valve on the discharge pipeline. 2. Increase the pressure at the outlet. 3. Check the pipeline flange connections and bolt tension ; 4. Check the gaskets at the suction inlet as well as those on the pump casing; if the gaskets are loose, replace them with new ones. 5. Check the voltage and the frequency of the motor. 6. Follow the direction indicator arrow on the chemical pump to reconnect the motor’s power cables or adjust the phase.
