1. What is the BF-4A High Pressure Concrete Cement Grouting Machine used for?
The BF-4A is a high-pressure grout pump designed for cement-based grouting and mortar conveying in applications such as concrete structures, railway tunnels, highway bridges, culvert slopes, subways, hydropower stations, dams, harbor works, crack and joint waterproof plugging, bolt grouting, backfill and curtain grouting, soft rock reinforcement, honeycombing repair and other underground or foundation treatments.
2. What are the main technical specifications of the BF-4A?
Model BF-4A; voltage options 220V/380V; motor power 4 kW (three-phase); delivery height up to 15 m; maximum output pressure 4 MPa; flow rate adjustable 0–6 L/min; bucket capacity 50 L; maximum aggregate size ≤5 mm; packing size 750 × 1000 × 1200 mm; weight 130 kg.
3. Which materials can the BF-4A pump?
It can pump cement slurry, yellow mud, water glass, oil, water and a wide range of mortar-type media including putty powder, latex paint, real stone paint, cement mortar, dry mortar, thermal insulation mortar, waterproof materials, fireproof materials and sound-absorbing materials. It can handle two different media simultaneously or one medium alone.
4. What is the maximum particle/aggregate size the pump can handle?
Maximum aggregate size is ≤5 mm. Do not feed larger particles or gravel-sized aggregates, which can damage the spiral pump core or block the system.
5. How is flow rate and pressure controlled?
Flow rate is adjustable (0–6 L/min) to suit job requirements. The pump delivers up to 4 MPa pressure and you should balance flow and pressure based on material viscosity and pipeline length—higher pressure typically reduces flow rate. The electric control box provides on/off control and basic operational management.
6. Can the BF-4A run continuously for long pumping jobs?
Yes — the design supports long-duration operations for pipe shed and small-pipe grouting. However, monitor motor temperature and pump performance, allow occasional cooldowns as needed, follow the recommended duty cycle from the supplier, and avoid running dry or under blocked conditions.
7. What power supply is required and how should it be connected?
The unit is available for 220V or 380V supplies and uses a 4 kW three-phase motor. Ensure the site power matches the selected voltage model, use appropriate wiring and circuit protection, and properly earth/ground the machine according to local electrical codes.
8. How portable is the machine and how should it be transported?
The BF-4A is relatively compact with a bucket capacity of 50 L and a total weight of about 130 kg. It is small enough for site mobility but heavy enough to require mechanical lifting or two or more people for safe handling. Use appropriate lifting equipment or a vehicle for transport; refer to packing dimensions (750 × 1000 × 1200 mm) for shipping.
9. What regular maintenance does the BF-4A require?
After each use flush the pump and hoses thoroughly with clean water to remove residual mortar. Regularly inspect and replace wear parts such as seals, valves, hoses and the spiral pump core. Lubricate moving parts as recommended, check electrical connections, and inspect the motor and cooling system for debris or overheating.
10. Are spare parts and consumables readily available?
Common spare parts include the spiral pump core, seals, valves, hoses, couplings and electrical components. Availability depends on the supplier or dealer — order replacement wear parts in advance for continuous projects and confirm compatibility with BF-4A model when ordering.
11. What safety precautions should operators follow?
Always wear appropriate PPE (gloves, eye protection, respirator if spraying, and protective footwear). Ensure the machine is properly grounded, match supply voltage, do not operate with damaged cables, avoid running the pump dry, relieve system pressure before maintenance, and keep clear of pressurized discharge points. Follow site-specific safety and lockout/tagout procedures.
12. How do I clean the pump after using cementitious or adhesive materials?
Immediately after use, flush the hopper, hoses and pump with clean water until discharge runs clear. For stubborn residues, use recommended cleaning tools and, if necessary, gentle mechanical scrubbing on accessible parts. Do not use aggressive chemicals that may damage seals unless manufacturer-approved.
13. What is the recommended material mixing ratio for mortar with this pump?
The description notes a material ratio (cement) of approximately 0.7:3 (cement to other components) for mortar. This is a guideline — always follow the specific material manufacturer's mixing instructions and adjust water content to achieve pumpable consistency suitable for the BF-4A.
14. Can the BF-4A pump two different media at the same time and how is that configured?
Yes, the BF-4A can pump two kinds of media simultaneously or a single medium separately. Configuration and mixing technique depend on the specific job and material properties; consult the supplier or operator manual for recommended feed arrangements, hoses and valves to achieve proper dual-feed operation without clogging or segregation.
15. What should I do if the pump clogs or the pressure drops unexpectedly?
Stop the unit, relieve system pressure, and inspect hoses, nozzles and the pump inlet for blockages. Check material consistency (too thick or containing oversize particles can cause clogging). Clean or replace blocked sections, verify valves and seals are intact, and restart gradually while observing pressure and flow. If problems persist, contact technical support.
