Doosan Hydraulic Pumps

Someone who works around hydraulics would agree strongly to having a proper schedule for the maintenance of hydraulic systems. The maintenance schedule ensures the peak performance of the machinery and eliminates costly repairs, downtime and safety hazards. The giant metallic arm and its operation work so efficiently as if they were equipped with joints, brains and muscles. This article is all about demystifying the actual science behind its operation, the significance of maintaining the hydraulic systems and marvel engineering. Let’s begin.

Understanding why hydraulic fittings and couplers fail:

Before getting into the maintenance part, it is essential to understand what causes failure.

Poor installation: Leaks, damages due to over-tightening and not using proper tools to install the couplers are some of the common poor installation methods. In other instances, the hydraulic fitting may be incompatible with the coupler which causes stress and risk of fatigue or damage to the fitting. Therefore ensure proper installation before running the system.

Deformed coupler: Potential physical damage distress or deformation can cause the coupler to perform poorly and lead to damage.

Vibration: Overusage of couplers or extending the usage beyond the recommended period also intensifies vibrations and leads to loosening of the fittings, leaks and failure.

Corrosion: Harsh climatic conditions, overexposure to moisture, chemicals, and other environmental factors have the potential to weaken the fittings and common causes of leakage or failure.

Proper maintenance and scheduling:

Hydraulic systems power a wide range of massive equipment and machinery, from cranes to excavators to presses and lifts. They operate under massive pressure, thus minor issues such as leaks, cracks and minor faults can lead to potential safety hazards. Lack of proper maintenance and scheduling could lead to failure of hydraulic systems or irreversible damage.

On the other hand, maintenance of Doosan Hydraulic Pumps ensures utmost efficiency and utilization of less energy and reduced wear and tear of the systems. Such factors reduce the operating costs and extend the life expectancy as well.

Excavators and pressers are utilized in significant projects that involve time restrictions, unplanned downtimes and breakdowns are something that are least expected.

The maintenance can be carried out by following steps:

  • Establishing maintenance schedule
  • Proper maintenance lists and checklist
  • Regular inspections
  • Cleaning
  • Lubrication of components
  • Monitoring leaks and signs of wear and tear
  • Monitoring the frequency of operation
  • Recording the operating environment.
  • Selecting the right hydraulic fluid 
  • Repairs and replacements – focusing on the life expectancies of every component.
  • Recording proper storage and transportation means utilized.


Ensuring all these check boxes are ticked and recorded helps in properly maintaining the entire hydraulic system. Loss of productivity and costly repairs can be avoided when these hydraulic systems are thoroughly investigated and maintained. Following the advice discussed in the article and other factors like addressing the issues related to the contamination of air and water, temperature issues and fluid levels ensures efficient operation of hydraulic systems.
