Complete Guide to Concrete Truck-Mounted Pump Maintenance & Repair

Ensure your equipment operates longer and more reliably. For any machinery, proper maintenance and repair are the keys to longevity—expecting peak performance without care is unrealistic.

The concrete truck-mounted pump is a vital category of construction equipment, combining the cost-effectiveness of a trailer pump with the mobility of a concrete pump truck. It's a common sight on job sites. This guide outlines standard maintenance and repair procedures—following the rules ensures optimal performance.

I. Maintenance Schedule

The truck-mounted pump consists of two main parts: the superstructure and the chassis.

1. Superstructure Engine:

• First Service: After the first 50 hours of operation. Change engine oil, filters, and fuel filters using OEM-specified parts.

• Routine Service: Every 300 operating hours thereafter, following the initial service standards. The engine is the power source—don't neglect its maintenance.

2. Hydraulic System:

• First Change: Replace all hydraulic oil and filters after the first 500 hours of operation, using the original oil and filter specifications.

• Routine Change: Replace hydraulic oil and filters every six months. To reduce costs, used oil can be filtered and reused, but this should not exceed two cycles before new oil is required.

3. Daily/Lubrication Maintenance:

• Hopper & Mixing System: Lubricate the hopper wear rings and mixing system regularly due to high wear. Manual grease points should be serviced every 50 hours.

• Grease Type: Use 000# grade grease in winter and 00# in summer to ensure proper flow.

4. Water Pump Care:

• Oil Change: The plunger-type water pump requires internal engine oil. Change this oil every six months (using 30# or 40# grade). Never run the pump dry.

• Filter: Clean the water pump filter monthly and replace it annually.

5. Chassis Maintenance:

• Engine: Service the chassis engine based on its actual operating hours.

• Battery: For equipment stored long-term, disconnect the battery and recharge it monthly to maintain health.

II. Repairs

1. Wear Parts Replacement:

• Regularly inspect and replace wear parts as needed: Pistons, S-tube, wear plate, cutting ring, mixer blades, concrete cylinder, discharge outlet, and seals. Timely replacement prevents abnormal wear and serious damage.

2. Electrical Components:

• Check traditional relays regularly for pitted, blackened, or loose contacts. Replace faulty relays promptly.

3. Chassis Repairs:

• Replace wear items like brake pads, clutch plates, and tires based on their condition and usage
