WIWA low-pressure pumps GX – the right pump for every system solution
WIWA low-pressure pumps GX reliably transfer paints, coating materials, isocyanates, water and cold glue from containers of any size – to supply spray units, paint circulation and dosing systems or individual workstations. They are driven by proven WIWA air motors. The fluid pumps feature a co-moving, spring-loaded piston packing, large material valves and coarse threads: even high-viscosity paints are drawn in easily, and the pump is quick to clean and easy to service. Twelve models in four performance classes from 4.33 to 36.18 l/min are available in carbon or stainless steel and in short or long design.
Your benefits
- Optimised material flow: large material valves draw in even high-viscosity paints and allow better cleaning of the pump
- Operator- and service-friendly: spring-loaded, co-moving piston packing for a long service life
- Easy assembly and disassembly: thanks to coarser threads on the fluid pump
- Closed system: the encapsulable solvent cup is a particular advantage with ISO materials
- The right version for every fluid: Standard, ISO, Water or Glue, carbon or stainless steel, short or long
- Flexible: optionally with a hydraulic motor for mobile systems, e.g. road marking
- Made in Germany: designed, built and tested by WIWA in Lahnau

The first figure stands for the output of the fluid pump, the suffix for the pressure ratio: the 146.03.7 delivers up to 8.8 l/min at a ratio of 3.7:1. The short design (K) is usually used with small containers, the long design (L) with 200-litre drums.
Applications
- Material transfer and paint supply
- Spraying and coating technology
- Paint and lacquer production and processing
- Painting companies, joineries, wood and furniture industry
- Automotive, aircraft industry, chemical and general industry
Good to know
The order numbers describe the pump consisting of air motor and fluid pump. Follower plates, suction kits, wall brackets, air regulators, hoses and guns are put together to suit your container and material – ready-made WIWA system solutions are available e.g. for small containers, 200-litre drums and 1000-litre IBCs.
