The product is the manxing High Power Motor Engine Concrete Sprayer, model CC-511.
The sprayer uses a 7.5 kW motor and is specified for 380V supply. Confirm you have the appropriate three-phase electrical supply and protection before installation.
The rated output is 5.5 m3/h. Actual output depends on mix design, aggregate size, hose length, and spraying conditions.
Maximum conveying distance is specified as 50 m. Performance at long distances depends on aggregate size, hose condition and bends—shorter runs generally give better results.
The specification lists a 'Max. Aggregate Size' of 80L. Because this metric can be ambiguous, confirm acceptable maximum aggregate diameter and grading with the manufacturer or supplier for your specific mix.
The spec lists a hose inner diameter of 10 mm. This appears unusually small for shotcrete applications—confirm hose compatibility and recommended sizes with the manufacturer before substituting hoses to avoid clogging or excess wear.
The specification indicates 'Air Consumption: 3Mpa'. This reads like a required air pressure figure—3 MPa is high, so verify required air pressure and compressor sizing with the manufacturer and use a properly rated air supply and fittings.
The product description emphasizes spraying wet concrete (wet-mixed shotcrete). If you need dry-mix shotcrete capability, check with the manufacturer whether this model supports it or if additional accessories are required.
Operators should use PPE (eye and face protection, respirators, gloves, hearing protection, and protective clothing), ensure proper grounding and isolation of electrical supply, secure hoses and fittings, follow lockout/tagout during maintenance, and receive training before operation.
Regularly clean the pump and hoses after each use, inspect and replace worn liners, pistons and seals, lubricate moving parts per manufacturer guidance, check electrical connections and motor condition, and perform scheduled inspections of hoses and couplings.
The machine includes a 3-year warranty. For details on what components and failure modes are covered, and the warranty claim process, contact the seller or manufacturer and retain your purchase and test documentation.
The product listing states that a machinery test report and video outgoing inspection are provided. Use these to verify performance on delivery and for warranty support.
Net weight is listed as 320 kg. Plan for lifting or moving with appropriate equipment (forklift, crane or pallet jack) and secure the unit during transport.
Check for blockages in hopper and hose, verify correct mix consistency and aggregate grading, inspect hose inner surface and connections, confirm motor and air supply are at proper settings, and consult the test report or service manual for part wear (pistons/seals).
It is intended for building wall spraying, wet concrete spraying, slope and tunnel work, structural strengthening and general shotcrete applications where a robust 7.5 kW spray pump is appropriate.
