Frequently asked questions about dosing pumps (FAQs)

How do I determine the right size of a metering pump for my application?

The right size of a metering pump depends on several factors, such as flow rate (amount of liquid per unit time), the pressure requirements of your system and the nature of the liquids to be handled. Analyse the required flow rate and pressure to support your application and take into account the variability in your process. Consult technical documentation and expert advice to choose a pump that meets your current and future needs.

Can metering pumps handle different types of liquids?

Yes, metering pumps are versatile and can handle a wide range of fluids, including corrosive, viscous and slurries. Choose the right pump design and materials for optimal handling. For example, use chemically resistant materials such as PVDF or stainless steel for corrosive liquids, and pumps with higher power or specific designs for viscous liquids to ensure efficient displacement.

What are the maintenance requirements for a dosing pump?

Regular maintenance is essential to maintain the reliability and accuracy of dosing pumps. This includes checking and replacing wear parts such as diaphragms, valves and O-rings, cleaning filter units and verifying pump settings and calibration. Maintenance frequency depends on operating conditions such as the nature of the fluid, usage patterns and environmental factors. Follow the manufacturer's recommendations and maintenance schedules to prolong pump life and ensure optimum performance.

How can I maintain the accuracy of my dosing pump over time?

Maintain the accuracy of your dosing pump through regular maintenance, calibration and attention to changes in operating conditions. Calibrate your pump according to factory specifications to keep operating within desired accuracy margins. Watch for changes in fluid properties or process conditions that may affect pump operation and adjust settings accordingly. By maintaining proactive pump management, you can optimise the performance and reliability of your dosing pump system.
