WIWA INJECT 2K 14025 GX – Working Safely with 2K Injection Technology
The WIWA INJECT 2K 14025 GX is a pneumatic 2K piston pump for precise injection work at a 1:1 ratio. This practical guide shows you how to set up the system correctly, avoid typical errors, and achieve consistently reproducible results – from sealing to floor and curtain injection.
Product Overview – WIWA INJECT 2K 14025 GX
| Feature | Practice-Relevant Details |
|---|---|
| Mixing Ratio | 1:1, positive-driven – no mixing errors |
| Max. Working Pressure | Up to 200 bar (depending on material) |
| Delivery Volume | Approx. 80 cm³ per stroke |
| Materials | 2K injection resins, PU resins, acrylate gels, injection foams |
Constant mixing ratio through positive-driven pumps
Separate flushing function for A & B components
For sealing, crack, curtain & floor injections
When using acrylate gels, it is recommended to pump both components separately before starting work. This ensures that there are no air bubbles in the system and that the mixing ratio remains stable.
Recommended Basic Settings (Guide Values)
- Air inlet pressure: approx. 4–6 bar (depending on material)
- Working pressure: 50–200 bar depending on the injection task
- Mixing ratio: fixed 1:1 (not adjustable)
- Hose lengths: keep as short as possible to minimize pressure loss
Pro Workflow – Step by Step
- Prepare material and stir until homogeneous if necessary
- Connect A and B components correctly
- Vent the system and pre-pump components separately
- Build up working pressure slowly
- Perform injection evenly
- Monitor pressure and adjust based on material intake
- Perform flushing process after finishing work
Typical Errors & Solutions
- Unsteady material flow: Reduce pressure, check venting
- Incomplete reaction: Check material temperature
- Pressure peaks: Check hose routing & packer clearance
- Rapid curing in the mixer: Shorten flushing intervals
Maintenance – Brief & Practical
- Daily visual inspection of hoses & couplings
- Regular flushing after every use
- Check seals for wear
- Check pressure gauges regularly
- Adhere to manufacturer maintenance intervals
