A Comprehensive Guide to Choosing a Macxi Magnetic Gear Pump

Complete Guide to Choosing a Macxi Magnetic Gear Pump

Choosing a magnetic gear pump is a crucial step when designing liquid transfer and dosing systems. The stability of operation, dosing accuracy, and service life of the entire system depend on the correct selection of equipment.

This guide compiles the main parameters that must be considered when choosing Macxi pumps.


1. Key Pump Selection Parameters

Liquid Viscosity

Liquid viscosity directly affects pump operation.

  • Low viscosity → possible internal leaks
  • High viscosity → requires higher torque and reduced speed

Liquid Flow Rate

The flow rate determines the required volume of liquid to be transferred per unit of time. Incorrect calculation can lead to unstable system operation.


System Pressure

Pressure affects pump load and design selection. High pressure requires a stronger and more robust series.


Liquid Temperature

Temperature affects viscosity and material compatibility. At high temperatures, it is important to consider the stability of seals and the casing.


Casing and Seal Materials

Correct material selection ensures resistance to chemicals:

  • 316L
  • PTFE
  • PEEK
  • FKM / FFKM
