Hydraulic Pump Repair Services in Crystal Lake, IL
Why Crystal Lake Industries Choose Us for Pump Repair
Piston, Vane, & Gear Pump Expertise: Whether it’s a high-pressure Rexroth piston pump from an excavator or a heavy-duty gear pump from a factory press, we handle the teardown, inspection, and rebuild.
Precision Bench Testing: We don’t just "fix it and ship it." Every pump undergoes rigorous pressure and flow testing to ensure it can handle the load before it ever reaches your site.
Local Logistics Advantage: Being minutes away from the Virginia Road industrial hub means we can offer faster pickup, delivery, and troubleshooting than out-of-state "mega-shops."
Common Pump Failures We Solve:
Aeration & Cavitation: Identifying the root cause of noise and vibration to prevent internal scarring.
Contamination Damage: Complete system flushing and internal component replacement (swash plates, pistons, and valve plates).
Seal & Gasket Blown-Outs: Rapid resealing to stop leaks and restore system efficiency.

Why Local Manufacturers Trust Our Valve Repairs
Opens in a new window www.hrparts.com
Tolerance Restoration: We utilize precision measurement tools to inspect spools and bores for wear that causes pressure drops and "creep."
Complete Resealing: Every rebuild includes a full high-performance seal kit to eliminate external leaks and internal cross-port contamination.
Clean Room Assembly: Valve assemblies are extremely sensitive to dirt. Our shop ensures a clean environment for disassembly and re-assembly to prevent premature failure.
Signs Your Control Valve Needs Service:
Cylinder Creep: The arm or attachment drifts slowly even when the controls are neutral.
Heat Generation: Excessive heat coming from the valve bank, indicating internal high-pressure bypassing.
Hesitation: Delayed response or "jerky" movement when activating a function.
Serving All Major Industrial Brands
While we focus on the repair of non-branded and universal industrial valves, we have extensive experience with systems from Bosch Rexroth, Parker, Husco, and Walvoil.
Precision Service for Complex Multi-Spool Systems
When a control valve malfunctions at a site in Crystal Lake or within the Virginia Road industrial corridor, your entire operation loses precision. Sticky levers, internal bypassing, or erratic cylinder movement are signs that your system’s "brain" is failing.
Sterig Hydraulic Repair offers specialized control valve diagnostics and rebuilding for industrial and mobile machinery. We handle everything from simple directional valves to complex, load-sensing multi-spool assemblies, ensuring your equipment responds with the accuracy it had on day one.
