The heart of hydraulic systems is hydraulic power units (HGU). With their basic components such as pumps, motors, valves, filters and oil tanks, they produce and direct all the energy of the system. Therefore, maintenance and servicing of the power unit should be carried out regularly, not only after a breakdown, but with a preventive maintenance approach.
What is a Hydraulic Power Pack?
Hydraulic power unit; It is a compact energy source consisting of an electric motor, hydraulic pump, valve group, oil tank, and cooling system. This unit provides movement by sending the necessary pressurized oil to the hydraulic cylinders or motors. However, in order for the system to work long-lasting and efficiently, oil quality, filtration, cooling system and sealing elements should be checked regularly.
Operations Applied in Hydraulic Power Pack Service
A professional hydraulic service not only replaces the faulty part; it analyzes, cleans and optimizes the system.
As Hidroman, our service process consists of the following steps:
Preliminary Inspection and Pressure Test
The unit's operating pressures, flow rates and leakage status are checked.
Pump, valve and motor performances are measured on the test bench.
Oil Analysis and Filtration Control
Hydraulic oil sample is taken, the pollution level is evaluated according to ISO 4406 standard.
If necessary, the system is cleaned by applying flushing.
Component Maintenance and Refurbishment
Pumps, valves and accumulators are renewed with original spare parts.
The electric motor and fan systems are checked, bearings are replaced.
Assembly and Commissioning Tests
After all assembly operations, the unit is operated at nominal pressure on the test bench.
Leak tests are performed, system efficiency is measured.
Post-Service Calibration and Reporting
At the end of each maintenance, system performance values are recorded.
Hidroman service team presents the operations performed to the customer with a detailed maintenance report. This report provides a great advantage for future maintenance planning and energy efficiency monitoring.
Benefits of Regular Hydraulic Service: Efficiency, Safety, and Longevity
Hydraulic systems are the most critical components of production lines, mobile machines or industrial facilities that operate under high pressure. However, these systems are not only with quality components; With regular maintenance and professional service, it becomes long-lasting and efficient.
As Hidroman, we can summarize the technical, economic and operational advantages of regular hydraulic service to businesses as follows:
Minimizes the Risk of Failure
Thanks to regular service, pressure losses, leaks, abrasions and oil contamination in the system are detected early.
This prevents major failures from occurring.
For example:
Pump or valve failure is usually caused by oil contamination.
Timely oil and filter changes prevent thousands of liras in repair costs.
Result: Unplanned downtime is reduced, production continuity is maintained.
Hydraulic Oil Extends Life
Hydraulic oil is the "lifeblood" of the system. Oil analysis and flushing (cleaning) processes carried out within the scope of regular service reduce the particle and moisture content in the oil.
With pollution control according to the ISO 4406 standard:
Oil quality is monitored,
System cleaning is done when necessary,
The chemical structure of the oil is preserved.
The result: Lower heat generation and less energy loss.
Improves Energy Efficiency
Problems such as pollution, leakage or wear reduce the hydraulic efficiency of the system. Thanks to regular service, system pressures and flow values remain within nominal ranges.
In this way:
The pump consumes less power,
Engine load is reduced,
Electricity consumption decreases.
Result: Energy savings of 10-20% are possible.
Extends Equipment Life
At every service maintenance, seals, bearings, seals and filters are checked and renewed. This significantly extends the life of hydraulic cylinders, pumps and valve assemblies.
The result: Less spare parts consumption, longer system life.
Provides Safe and Standard-Compliant Operation
Regular servicing includes maintenance protocols in accordance with ISO 4413 and ISO 9001 standards. Pressure tests, leak checks and accumulator safety tests are carried out regularly.
This increases both personnel safety and system reliability.
Result: Occupational accidents and environmental risks are reduced.
Fault History and Performance Tracking
Every transaction made in professional services is recorded.
Hidroman service team provides a detailed service report at the end of each maintenance:
Pressure and flow measurements
Oil analysis results
Changed parts list
Subsequent care recommendations
The result: System history becomes traceable, making preventive maintenance planning easier.
Business Continuity and Cost Advantage
Regular servicing minimizes unplanned downtime, maintaining production continuity. It prevents business losses and sudden costs due to breakdowns.
The result: lower total cost of ownership (TCO) and increased operational efficiency.
Stay Safe with Hidroman Service Team
