HrvatskiHow to Identify Faults and Ensure Hydraulic System Longevity
Piston pumps are the absolute heart of any demanding hydraulic system. Due to operating under extremely high pressures and in harsh environments, components such as pistons, cylinder blocks, valve plates, and seals inevitably wear out over time. When machine performance drops, a timely and expert piston pump service is the only reliable way to prevent costly downtime in production or construction operations.
At Hidel, we specialize in the diagnostics, overhaul, and repair of hydraulic pumps and motors, restoring your equipment to factory specifications.
Common Signs of a Piston Pump Failure
Ignoring minor changes in machine performance is the most frequent cause of catastrophic pump failure. If you notice any of the following symptoms, it is time for an inspection:
- Loss of pressure and operating power: The machine runs slower or fails to lift its usual load.
- Increased noise and vibration: Unusual sounds (such as grinding or knocking) typically indicate cavitation, worn bearings, or damaged pistons.
- Hydraulic oil overheating: When internal components no longer seal properly, internal oil leakage occurs, drastically raising the system temperature.
- Oil traces around the pump: Damaged hydraulic seals cause leaks, leading directly to pressure loss and environmental contamination.
What Does a Professional Piston Pump Overhaul Look Like at Hidel?
We approach every service systematically and precisely, utilizing modern tools and high-quality components. Our process includes:
- Fault Finding and Detailed Cleaning: We completely disassemble the pump (as shown in the image above) and thoroughly clean all internal elements to precisely determine the degree of wear.
- Component Replacement and Machining: We replace worn pistons, swash plates, valve plates, and install exclusively brand-new, high-quality hydraulic seals. When necessary, we perform precision honing of barrels and cylinder blocks.
- Load Testing: Before delivery, every serviced pump undergoes rigorous testing on our test benches to verify that it achieves its rated operating pressure and flow.
Why Choose Hidel for Hydraulic Services?
When you entrust your repair to our expert team, you gain speed, reliability, and a long-lasting solution:
- Experience with Leading Brands: We successfully service axial-piston and radial-piston pumps from all renowned global manufacturers (Rexroth, Parker, Linde, Sauer Danfoss, Eaton, and others).
- Cost Reduction: Through proper machining and the replacement of critical parts, we often eliminate the need to purchase an expensive new pump, saving your budget.
- Preventative Maintenance: Along with the repair itself, we provide our clients with advice on the proper selection of hydraulic oil and system maintenance to maximize the pump’s lifespan.
Don’t wait for a minor issue to turn into an expensive operational shutdown. If your piston pump shows signs of wear, leave it to the professionals.
