ZZ-S3 Fireproof Mortar Spraying Machine

The ZZ-S3 is designed to spray fireproof mortars and related pastes such as corrosion‑resistant mortar, cementitious and polymer‑modified fireproofing mixtures. Typical applications include fireproofing of steel structures, concrete surfaces, tunnels, ducts and other construction and industrial protection projects.

Key specs: voltage 380V~50Hz (three‑phase), power 4000W, hopper capacity 75 L, delivery pressure 40 bar, delivery flow 3–35 L/min, maximum conveyed distance up to 60 m, maximum particle/grain size ≤ 6 mm, dimensions 91 × 60 × 119 cm. Weight is approximately 140–190 kg depending on configuration and optional fittings—confirm with your supplier.

The machine can spray pumpable pastes and mortars that are compatible with a maximum particle size of 6 mm. This includes many fireproof mortars, corrosion‑resistant mixes, renders and some adhesive/repair mortars. Very coarse or heavily armoured mixes that exceed 6 mm should be screened or are not suitable.

Maximum recommended particle/grain size is 6 mm. Particles larger than 6 mm can clog or damage the pump and reduce performance.

Delivery flow ranges from about 3 to 35 liters per minute depending on material consistency and nozzle settings. Maximum delivery pressure is 40 bar. Actual throughput will vary with material viscosity, hose length/diameter and vertical lift.

The machine is rated to convey material up to about 60 meters (hose length). Note that longer distances and vertical lifts will reduce flow rate and may require adjustments or shorter hose runs—confirm specific job requirements with the supplier.

The unit requires a 380V, 50Hz three‑phase supply and consumes up to about 4 kW. Install on a properly rated circuit with suitable protection and grounding. Have a qualified electrician verify compatibility on site.

Prepare mortar to a uniform, pumpable consistency free of large lumps. Sieve or screen aggregates to ≤6 mm, follow the mortar manufacturer's water ratio and mixing instructions, and remove air pockets. Do a small test run to confirm pumpability and spray pattern before full application.

Position machine on a stable surface, connect power and grounding, fill the 75 L hopper with properly mixed material, attach feed and spray hoses, set pressure/flow controls, perform a test spray, then proceed with spraying. Refill the hopper as needed and monitor pressure and material consistency throughout the job.

After each use flush and clean the hopper, pump, hoses and spray gun to prevent material hardening. Regularly inspect and replace wear parts (nozzles, seals, screws/augers, hoses), check electrical connections, and lubricate moving parts per the manufacturer manual. Keep a log of usage and part replacements.

Common consumables include spray nozzles/tips, high‑pressure hoses, seals/gaskets, rotor/stator or screw/auger components, valves and any hose couplings. Keep several wear parts on hand to avoid downtime—your supplier can recommend a parts kit.

Wear appropriate PPE: respirator or dust mask, safety goggles, gloves, hearing protection and protective clothing. Ensure electrical grounding and emergency stop access. Do not spray flammable materials and avoid inhalation of dust. Follow lockout/tagout procedures for maintenance and consult the operator manual for machine‑specific safety instructions.

The ZZ‑S3 is compact (91 × 60 × 119 cm) and described as having flexible movement suitable for construction sites. Weight is substantial (~140–190 kg), so check whether your supplied model includes wheels or lifting points and plan for suitable transport (forklift, crane or vehicle) as needed.

Yes—the machine is intended for sustained construction use, but continuous performance depends on proper mixing, timely hopper refills, cooling periods and routine checks. Follow the manufacturer's duty‑cycle guidance in the manual and monitor motor temperature and pump performance during extended operation.

The ZZ‑S3 supports OEM/ODM customization. Warranty terms and after‑sales service vary by seller and region—confirm the warranty period, spare parts availability and local service options with your supplier before purchase.
