1. What materials can the Concrete mortar grouting pump cement Spray Machine handle?
It can pump viscous and fluid grouting materials such as mortar, cement slurry, grout, waterproofing compounds, caulking agents and other grouting materials compatible with a maximum particle size of under 5 mm.
2. What is the model and main technical specification of this machine?
Model QJ-M50. Electric supply 380V/220V, motor power 3 kW or 4 kW, conveying flow up to 3 m3/h, maximum pressure 3 MPa, maximum conveying distance 20 m, conveying height 5–15 m, through particle size <5 mm, bucket capacity 50 L, external dimensions 1230×520×990 mm, weight 160 kg.
3. Can the machine spray cement and cement-based mortars?
Yes. The unit is designed for cement slurry and cement-based mortars provided the mix is fluid enough and particles are smaller than the machine's maximum through-particle size (<5 mm).
4. What power supply options are available and how do I choose?
The machine supports 380 V or 220 V electric supply. Confirm with your supplier which voltage version is provided or order the version that matches your site power. Use a properly rated and grounded power source.
5. What are typical operating limits for distance and height?
Rated maximum conveying distance is 20 m and conveying height is typically 5–15 m. Actual performance depends on material viscosity, mix consistency, hose diameter and number of bends—denser mixes reduce achievable distance and height.
6. What is the maximum particle size the pump can handle?
The specification lists a maximum through particle size of under 5 mm. Using larger particles increases the risk of blockages and damage.
7. How much material does the machine hold and how portable is it?
The hopper/bucket capacity is 50 L. The machine weight is about 160 kg, so while compact, it may require two people or mechanical lifting (dolly, pallet jack or forklift) for transport and placement.
8. What routine maintenance is required?
Clean the pump and hoses thoroughly after each use (flush with water or suitable cleaner until clear), inspect and replace worn seals, check hoses and couplings for wear or leaks, grease any lubrication points per the manual, and verify electrical connections and motor condition regularly.
9. How do I clean the pump after use to prevent clogging?
Immediately after use, rinse and flush the hopper, pump chamber and hoses with plenty of water (or appropriate solvent for non-water-based materials) until the discharge runs clear. Disassemble and clean any removable wear parts if material has started to set.
10. What safety precautions should operators follow?
Wear appropriate PPE (gloves, eye protection, dust mask/respirator as needed), ensure equipment is properly grounded, do not exceed the rated pressure (3 MPa), secure hoses and fittings, isolate power before maintenance, and follow safe lifting/handling procedures for the 160 kg unit.
11. What could cause reduced flow or pressure and how do I troubleshoot?
Common causes: hose blockages, air in the line, incorrect material mix (too thick or too sandy), worn seals or pump parts, electrical motor issues. Troubleshoot by checking for blockages, purging air, confirming correct material consistency, inspecting seals/hoses, and verifying motor power and connections.
12. Are replacement parts, nozzles and accessories available?
Spare parts and accessory items (hoses, nozzles, seals, couplings) are typically available from the manufacturer or supplier. Check with your supplier for compatible accessory options and part numbers.
13. Can I use waterproofing grouts and chemical admixtures with this pump?
Yes, many waterproofing grouts and admixture-modified mortars are compatible as long as the final mix remains pumpable and particle size limits are respected. Always follow the material manufacturer's mixing instructions and test pumpability before large-scale use.
14. What storage and environmental conditions are recommended?
Store in a dry, covered area protected from freezing temperatures and direct sun. Clean thoroughly before long-term storage to prevent material hardening in the pump. Protect electrical components from moisture.
