How to Resolve Common Issues with Snowate Metering Pumps

Troubles & Solutions

As precision fluid delivery equipment, the stability and accuracy of metering pumps directly impact production safety and efficiency in industries such as chemical and pharmaceutical manufacturing. Common issues such as abnormal flow, leakage, vibration, and pressure fluctuation, if not addressed promptly, can result in decreased metering accuracy, energy waste, equipment damage, unplanned shutdowns, or even safety incidents. Therefore, systematically mastering the Snowate metering pump common issues and solutions not only enhances equipment reliability and extends its service life, but also reduces operation and maintenance costs through preventive maintenance, ensuring production continuity and process stability. This is especially critical in high temperature, high pressure, and flammable or explosive conditions.

Various models of metering pumps arranged in the production workshop

Table 1: Snowate Metering Pump Common Issues and Solutions
Fault Description	Possible Causes	Solutions
Reduced discharge flow, significant pressure fluctuation	Inlet blockage, improper flow valve adjustment, internal pump damage	Clear inlet blockage, adjust the flow control valve, and replace pump impeller.
Excessive noise	Unstable installation, bearing wear, loose valves	Reinstall the pump, replace worn bearings, and tighten valves.
Pump leakage	Seal aging, damaged gaskets, loose connections.	Replace seals/gaskets; secure connections.
Difficult startup	Power supply circuit failure, motor damage, air intake system failure	Check power supply circuit, replace the damaged motor, and repair the air intake system.
Excessive operation vibration	Unstable installation, bearing wear, impeller imbalance.	Reinstall the pump, replace worn bearings, and balance impeller.
Unstable outlet pressure	Significant medium temperature variation , improper valve adjustment, internal pump clogging	Control fluctuations in medium temperature, adjust valves, and clear internal blockage.
Motor overheating	Voltage fluctuation, motor overload, and poor ventilation.	Stabilize power supply voltage, reduce motor load, and improve ventilation conditions.
Oil leakage	Oil seal aging, damaged sealing gaskets, and oil passage blockage	Replace oil seals and sealing gaskets, and clean the oil passages.
Unstable pump operation	Improper inlet/outlet valve adjustment, motor failure, and bearing wear.	Adjust valves, replace the damaged motor, and replace worn bearings.
