04 / Installation
Application Guide
- 01Locate the leak and clean the substrate around it
- 02Drill 2–3 cm of crack on each side at ~45° angles
- 03Insert injection packers and tighten with the T-handle wrench
- 04Load the prepared slurry into the hopper and power on the pump
- 05Open the gun valve first, then start injection at the machine end
- 06After at least 48 hours, remove packers and finish the substrate flush
- Always wrap thread connections with PTFE tape or sealant to prevent leaks
- Tighten all bolts on the pump body before operation
- Connect motor and pump body tightly — do not run dry
- Flush the pump with cleaning agent immediately after grouting to preserve internals
- Wear PPE — protective glasses, gloves, work clothes, and boots are required
05 / Storage & Safety
Transport, Storage & Safety
Storage & Transport
Store the pump in a dry, ventilated indoor location between -10 °C and 40 °C. Flush internal lines with cleaning solvent after each use to prevent grout hardening. Keep covered when idle.
Shelf Life
Designed for 5+ years of service life under regular maintenance and proper storage.
Precautions
- Wear full PPE (gloves, goggles, work clothes, boots) during operation
- Never run the pump dry — always ensure grout is in the hopper
- Flush with cleaning solvent immediately after each grouting session
- Inspect pressure gauge, hoses, and fittings before each use
- Disconnect power before any maintenance or cleaning
