1. Pumping System Parts
These are high-wear components due to concrete abrasion:
Wear plate and cutting ring (or wear ring)
Concrete piston (rubber piston or piston cup)
Delivery cylinder (S-tube or concrete cylinder)
Mixing hopper sieve and agitator blades
S-valve or Rock valve and its shaft bushings/seals
2. Hydraulic System Parts
Hydraulic parts ensure arm and pump motion:
Hydraulic hoses (various lengths and pressure ratings)
O-rings and sealing kits
Hydraulic filters (return, suction, pressure)
Hydraulic oil (recommended grade)
Solenoid valves or proportional valves
3. Spraying System Parts
Important for stable spraying quality:
Spray nozzle assemblies (complete sets and tips)
Accelerator pump parts (diaphragm, valves, hoses)
Air hose fittings and clamps
Water control valve and pressure gauge
4. Electrical and Control Parts
Keep these for control safety and reliability:
Remote control battery / charger
Control panel switches, relays, and fuses
Sensors (pressure, temperature, stroke sensors)
5. Miscellaneous and Maintenance Items
Grease and lubricants
Hopper rubber seals and gaskets
Cleaning balls for delivery pipe
Concrete delivery pipes and elbows
Clamps and rubber gaskets for pipeline joints
Would you like us to make a detailed spare parts checklist (with part names, functions, and recommended stock quantities) for a specific model of wet shotcrete machine (e.g., 30 m³/h, 40 m³/h, or truck-mounted type)?
