Key Product Advantages

A Large Outrigger Span & High Stability
The front leg adopts a horizontal telescopic cylinder + H-type legs, providing a large span. The rear leg adopts an eight-character closed type layout, giving excellent support and resistance against pumping impact loads on the rear hopper.
B High-Efficiency Pumping System
Utilizes a 55KW four-pole motor with a 130ml/r adjustable displacement main pump and a 45ml/r variable pump (Rexroth series). The main valve incorporates imported proportional valves (BARMAG) from Germany with fixed-variable switching functionality.
C Symmetrical Boom Structure
Designed with a symmetrical layout where the telescopic arm connects directly to the base arm on the same axis through a pin. This eliminates connecting arms, lateral forces, and stress concentrations, effectively preventing fatigue cracking.
D Flexible Swing Arm
The boom swings up to ±45°, dramatically increasing the flexibility of the jet mechanism. This increases the single sprayable area, leading to smoother surfaces while reducing turntable rotation frequency.
E High-Strength Boom Section
Telescopic arm constructed using four BS700 high-strength steel plates. Weld joints feature lap bars to maximize boom rigidity, ensuring minimal vibration during wet spraying operations for a premium spray finish.
F Reinforced Rotary Drive Mechanism
Employs a turbo-type gear reduction mechanism for a high reduction ratio, high self-locking torque, and ultra-smooth operation. Uses recognized high-torque, large displacement rotary motors with proportional valve control to ensure rotation without jitter.
G Reliable Electrical Control System
Top-tier electrical system layout. Remote control utilizes robust domestic brands with extended range and powerful anti-drop signals. Features international premium brand electric components, including Siemens.
H Quick-Setting Agent Filling System
The accelerator pump is driven by a variable frequency motor. An inverter precisely adjusts the flow rate in synchronization with the concrete pumping speed. Large 2600L/h diaphragm pump fills a 1000L tank in just 20 minutes.

Wet vs. Dry Shotcrete Technology

Both technologies are commonly used for thin-walled structures such as tunnel lining, walls, ceilings, and steel structure coatings.

Dry Spraying Machine: Mixes cement, sand, and gravel in a dry state, then uses compressed air to deliver materials to the nozzle where it is mixed with pressure water. This method demands highly skilled operators, limits aggregate particle size, and produces significant dust pollution and high rebound rates.
Wet Spraying Machine: Pumps pre-mixed concrete straight to the nozzle while mixing compressed air and accelerator at the outlet. This achieves a highly homogeneous mixture, rapidly solidifies materials, greatly reduces rebound rates, and features a significantly higher operating efficiency with fully controlled material quality.

Wet spraying machine is widely used for concrete spraying operations in places such as mines, tunnels, culverts, railways, hydro-power projects, underground engineering, and revetment.

Main Characteristics of Hydraulic Pump-Type Wet Spraying Machine

  • Stable Delivery: Hydraulic pumping system ensures consistent performance and delivery capacity.
  • High Construction Efficiency: Large volume of delivery and long conveying distances.
  • Superior Concrete Quality: Sprayed concrete is exceptionally dense, homogeneous, and of high strength.
  • PLC Controlled Main Pump: Variable displacement piston pump of constant power, with output volume controlled easily via PLC.
  • Extended Service Life: High-strength S-pipe, wear plates, and cutting rings inlaid with wear-resistant hard alloys.
  • Multi-Point Lubrication: Automatic electric lubricating pump effectively reduces wear-out of critical parts.
  • Air Cooling System: Air cooling design eliminates water-freezing damage during winter operations.
  • Accurate Accelerator Dosing: Stepless speed regulation with high-accuracy metering pumps.
  • Operator Health Protection: Considerably lowers dust concentration at the nozzle and surrounding air.

System Configurations

Power System
Equipped with high-performance motors and diesel engines from domestically famous brands.
Main Oil Pump
Utilizes a variable plunger pump system with integrated overpressure relief to guarantee reliable operation and motor protection.
Lubrication System
Five-point separate, "point-to-point" lubrication targeting critical components to prolong machinery lifetime.
Accelerator Metering Pump
Reciprocating piston diaphragm pump offering high temperature, erosion, and abrasion resistance alongside stepless speed regulation.
Electronically Controlled Reversing System: Low pumping pressure coupled with high reversing speed reduces reversal impact and operator labor. Two separate hydraulic circuits stabilize oil supply, while accurate PLC control increases swing cylinder reversing speed for a continuous, uniform discharge.

Frequently Asked Questions

What are the main applications of the wet concrete shotcrete pump?
The wet spraying machine is widely utilized in mines, tunnels, culverts, railways, hydro-power projects, underground engineering, and slope protection revetments.
How does wet spraying compare to dry spraying machines?
Wet spraying uses thoroughly pre-mixed concrete, conveying it through a pumping system and adding compressed air and accelerators at the nozzle. This creates a dense, homogeneous result with significantly lower rebound rates and minimal dust pollution compared to dry spraying.
What power options are available for these shotcrete pumps?
The pumps support multiple flexible configurations, including electric motors, diesel engines, or generator drives to match diverse job site environments.
How is the accelerator dosing managed?
It features a variable frequency motor driven accelerator pump. A PLC/inverter automatically scales the accelerator flow in proportion to the actual concrete output, providing highly accurate, stepless speed regulation.
What makes the symmetrical robotic boom system more reliable?
The telescopic arm directly aligns with the base arm on a single axis through a pin. This symmetrical design prevents lateral forces and stress concentration, virtually eliminating fatigue cracking issues common in unsymmetrical booms.
What is the warranty and after-sales service policy?
We offer a half-year warranty for non-human damage (excluding wearable parts). We also provide lifelong technical support, free operator training, fast shipment of replacement parts, and dispatch engineers for on-site services.
