WIWA INJECT HD 4 – powerful 1K injection pump for cracks, joints and voids
The WIWA INJECT HD 4 is a pneumatic 1K piston pump based on proven WIWA PHOENIX pump technology. It stands out for its high output and large valves, making it suitable for more viscous injection materials as well. Spring-preloaded packings make it particularly low-wear, and the pump starts reliably even at very low air inlet pressure. All fluid-carrying parts of the pump are made of stainless steel. With a high-pressure filter and tip, the unit can also be used as an airless sprayer.
Your benefits
- High output: large valves, also suitable for viscous materials
- Low wear: spring-preloaded packings, solvent cup protects piston rod and packings
- Reliable start: pump starts quickly even at very low air inlet pressure
- Modular: pressure ratio and output can be adapted by exchanging a few components
- Stainless steel: all fluid-carrying parts of the pump in stainless steel
- Versatile: with high-pressure filter and tip also usable as an airless sprayer
