Common Concrete Pump Problems We Diagnose and Repair  

Concrete pump failures often stem from hydraulic system issues that require specialized diagnosis and repair. Our technicians regularly address hydraulic leaks affecting pump or boom operation, which can cause reduced pressure or complete boom control loss. S-valve malfunctions are another common problem, leading to concrete blockages or flow irregularities that slow work progress. We also repair excessive wear on cylinders, seals, and wear plates that naturally occur during heavy pumping. Hydraulic control issues causing boom positioning problems often indicate worn outrigger stabilizers or compromised hydraulic power, both of which need immediate attention. Pipeline blockages from hardened concrete can damage delivery pipes, requiring cleaning and component replacement. Our diagnostic process includes inspecting the hopper and agitator systems, analyzing hydraulic pump noise for wear, and examining joints, connections, and seals where leaks often develop.  

Concrete Pump Maintenance and Parts Replacement  

Preventive maintenance represents the most cost-effective approach to concrete pump ownership, and Western Mixer Diesel Repair offers comprehensive maintenance programs tailored to your equipment’s operational demands. Our hydraulic system service includes complete fluid analysis, filter replacement, and pressure testing to ensure optimal performance of all hydraulic components. We provide professional pipeline cleaning services using specialized equipment that removes concrete buildup without damaging delivery pipes or connection points. Wear plate replacement services utilize OEM or equivalent parts designed to withstand the abrasive nature of concrete pumping operations. Our S-valve rebuild services restore proper concrete flow control and eliminate the blockages that cause costly jobsite delays. Cylinder seal replacement represents a critical service that prevents hydraulic fluid contamination and maintains proper pumping pressure throughout your concrete pump’s operational cycle. Additionally, our outrigger repair services ensure your concrete pump maintains proper stability during operation, protecting both equipment and job site personnel from dangerous positioning failures.
