For any water treatment or chemical system, the stable operation of the Chemical Metering Pump is crucial for ensuring dosing accuracy and system safety. While our chemical metering pumps are renowned for their high precision, long lifespan, and corrosion resistance, proper routine maintenance can further extend their lifespan and operational efficiency. Below are some practical maintenance tips, explained in conjunction with the structural advantages of our products.
During long-term operation, chemical residues or impurities may accumulate inside the pump body, affecting diaphragm movement accuracy. We recommend that users regularly clean the pump head and valve body to ensure unobstructed flow. Our chemical metering pumps are designed for easy disassembly and assembly, allowing maintenance personnel to quickly open the pump head for cleaning, minimizing downtime.
The diaphragm is a critical component affecting pump stability. Although our high-strength PTFE diaphragms offer excellent corrosion resistance and fatigue resistance, under high-frequency or high-pressure conditions, we still recommend checking their elasticity and sealing every 6–12 months and replacing worn parts promptly to prevent leaks.
Operating the metering pump in a dry state can easily lead to overheating or wear of the seals. Our pumps feature built-in overpressure protection and anti-dry-run design, effectively preventing such damage. However, operators should still ensure sufficient liquid and stable pressure in the suction line before startup.
Impurities or crystalline particles in the chemical can cause valve blockage or wear. It is recommended to install a filter and replace it regularly. Our pump valves are made of wear-resistant engineering plastics, maintaining good sealing even in media with microparticles, further extending service life.
After prolonged use, the actual output flow rate of the pump may deviate slightly due to wear or environmental changes. Regular flow calibration and operational testing are recommended. Our pumps have a precise adjustment mechanism, are easy to operate, and can be quickly calibrated via digital display or control system.
With its advanced structure, ease of operation, strong corrosion resistance, and long service life, our Chemical Metering Pump demonstrates extremely high reliability in routine maintenance. By following a scientific maintenance strategy, the pump can ensure continuous and stable operation in various demanding environments, bringing higher production efficiency and lower operating costs to enterprises.
