Hidroman provides professional Rexroth hydraulic service and repair solutions for hydraulic pumps, hydraulic motors, valves, and other hydraulic components used in demanding industrial and mobile applications.
Our technical service approach focuses on identifying the root cause of hydraulic failures rather than simply replacing components. Each service requirement can be evaluated according to the component model, operating pressure, flow rate, application, oil condition, and reported failure symptoms.
Our Rexroth service solutions are suitable for industrial machinery, construction equipment, mining equipment, mobile hydraulics, manufacturing systems, and heavy-duty hydraulic applications.
Hydraulic component failures can result in reduced machine performance, unexpected downtime, and costly production interruptions.
Hidroman provides technical service solutions for Rexroth hydraulic components, including:
The appropriate service procedure depends on the component condition and the operating requirements of the hydraulic system.
The hydraulic pump is one of the most critical components in a hydraulic system. Pump wear or internal leakage can cause pressure loss, reduced flow, excessive noise, overheating, slow machine movement, and declining system performance.
Our Rexroth hydraulic pump repair and rebuild process may include:
Where applicable, testing helps verify pump performance before the component is returned to service.
Rexroth hydraulic motors are widely used in mobile and industrial hydraulic applications where controlled torque and reliable hydraulic power transmission are required.
Symptoms such as reduced torque, inconsistent rotation, excessive noise, overheating, external leakage, or reduced operating speed may indicate a hydraulic motor problem.
Hidroman provides Rexroth hydraulic motor inspection, repair, rebuild, and testing services based on the condition of the individual component.
The service process may include component inspection, replacement of worn parts, sealing element replacement, reassembly, and functional testing.
Hydraulic valves control pressure, flow, and directional movement within hydraulic systems. Contamination, mechanical wear, damaged seals, incorrect adjustment, or internal leakage can affect valve performance.
Our Rexroth valve service may include:
When a valve problem is detected, the surrounding hydraulic circuit should also be considered because valve performance can be affected by contaminated oil, incorrect pressure settings, pump problems, or other system-related issues.
A hydraulic failure does not always originate from the component that first shows the symptom.
For this reason, effective Rexroth hydraulic troubleshooting should consider the complete hydraulic system.
Low Hydraulic Pressure
Possible areas for inspection include:
Potential causes may include:
Hydraulic noise can be associated with:
Possible causes include:
A systematic troubleshooting process can help identify the actual cause of the failure before unnecessary component replacement.
Hydraulic fluid cleanliness has a direct impact on the operating life and performance of hydraulic components.
Contaminated hydraulic oil can accelerate wear in pumps, valves, motors, cylinders, and other precision components.
Hidroman provides hydraulic flushing and filtration solutions for systems requiring improved fluid cleanliness.
Flushing and filtration may be considered after:
The required cleanliness level should be determined according to the hydraulic system, component manufacturer requirements, and application.
Testing is an important part of hydraulic component service.
Depending on the component and application, testing can be used to evaluate:
Testing results can help document the condition of the component following repair or rebuild.
Hidroman also manufactures hydraulic test equipment and service machinery for professional hydraulic maintenance operations.
Many industrial and mobile machines remain in service for years or decades. As a result, maintenance teams may encounter older Rexroth, Mannesmann Rexroth, or Hydromatik hydraulic components.
Depending on component condition and available parts, older hydraulic components can be evaluated for repair, rebuild, or replacement.
Providing the complete model number, serial number, photographs, and application information helps our technical team determine the appropriate service approach.
Hidroman can evaluate service requirements for a wide range of Rexroth hydraulic components, including:
For a faster technical evaluation, please provide the component model code and serial number whenever available.
Our hydraulic service solutions can be applied to hydraulic equipment used in:
The service procedure is determined according to the component, hydraulic circuit, operating conditions, and failure symptoms.
Hydraulic component repair should address more than the visible failure.
Hidroman combines hydraulic engineering, component service, testing, filtration, flushing, and hydraulic system expertise to evaluate hydraulic equipment as part of the complete system.
Our capabilities include:
Our approach is focused on identifying the cause of hydraulic problems and helping customers reduce unexpected equipment downtime.
If you need Rexroth hydraulic pump repair, Rexroth pump rebuild, hydraulic motor repair, valve repair, or hydraulic system troubleshooting, send us the component model number, serial number, photographs, application details, and known failure symptoms.
Our technical team can review the available information and determine the appropriate service or repair approach.
Don't wait for a hydraulic failure to stop your machine. Plan hydraulic inspection and maintenance before unexpected downtime occurs.
