Variant overview – gear ratios & designs

WIWA GX low-pressure pumps are available in different transmission ratios and in various material designs. This allows the pump to be optimally adapted to the delivery pressure, material type and application environment.

Option Typical application
Transmission ratio 3.7:1 – 15:1 Adaptation to required delivery pressure and material viscosity
Standard rust and acid resistant (short / long) Universal industrial applications with chemical exposure
ISO design (short/long) For isocyanate-containing or reactive materials
Glue version (short/long) Especially for adhesives and viscous media
Water version (short) For water-based materials
Normal steel versions (short/long) Economical solution for less aggressive media
Note: The selection of gear ratio, design (short or long) and material version should be based on material viscosity, chemical exposure and desired delivery pressure.
Setup & commissioning
  • Check the compressed air supply and adjust it correctly
  • Check material connections & seals
  • Select the appropriate design according to the material
  • Perform regular maintenance on the seals
  • Observe flushing and cleaning intervals
Tip: A correctly adjusted compressed air supply increases the service life of the pump and optimises the delivery rate.
Intended use / applications
  • Industrial material conveyance
  • Extrusion & dosing applications
  • Adhesive and sealant conveyance
  • Chemically contaminated production environments
