• Rotor-stator precision pumping - Progressive cavity system ensures smooth, non-pulsating flow and reliable pressure control, even with abrasive mixes.
• Long-distance pumping capability - Supports up to ~300 ft horizontal and 200 ft vertical pumping (material-dependent) for large-scale site coverage.
• Integrated spray and grout versatility - Works with optional guns and accessories to switch between open hose grouting and spray applications efficiently.
• Jobsite-ready heavy-duty build - Reinforced chassis with towable design ensures durability, mobility, and stability in harsh construction environment

Q&A

Maintenance Tips

• Flush immediately after use: Run clean water through hopper, pump, hose, and spray nozzle to prevent grout hardening and blockages.
• Clean pump system thoroughly: Ensure piston, valves, and delivery lines are fully free of residue to maintain steady pressure output.
• Inspect hoses regularly: Check for cracks, swelling, or internal buildup that can restrict flow or reduce spraying consistency.
• Maintain seals & valves: Replace worn O-rings and check valves to avoid pressure loss and leakage during operation.
• Check spray nozzle condition: Keep nozzle clean and free of hardened particles for uniform grout application.
• Monitor motor performance: Ensure smooth operation with no overheating or irregular vibration during continuous use.
• Tighten all fittings: Verify clamps and connections are secure before each job to handle high-pressure pumping safely.
• Store dry & clean: Fully empty and rinse system, then store in a dry place to prevent corrosion and internal buildup.
