Hydraulic Design Philosophy in Doosan Machines

Doosan excavators are engineered to operate under heavy load, repeated shock, and long daily running hours. To achieve this, Doosan adopts carefully balanced pump–motor combinations rather than generic hydraulic layouts.

In Doosan equipment, hydraulics are responsible for:

• Power generation for digging and lifting

• Controlled rotation during loading cycles

• Stable crawler movement on uneven ground

• Consistent output across long shifts

Any mismatch in pump or motor specification can disturb this balance, leading to efficiency loss and component stress.

​

Hydraulic Pump Brands & Model Series Used in Doosan Excavators

Doosan excavators primarily rely on high-efficiency axial piston pumps, selected for durability and smooth response.

​

Kawasaki Precision Machinery – Main Working Pumps

Kawasaki pumps are widely used in Doosan machines due to their pressure stability and long service life.

Common Kawasaki Pump Models

• K3V63DT – Compact and mid-size Doosan excavators

• K3V112DT – Standard 20–22 ton class

• K3V140DT – Heavy-duty excavation applications

• K5V140 – Improved efficiency and higher pressure variants

• K5V200 – Large excavators and continuous-duty cycles

These pumps support multi-function operation without sudden power drop.

​

Bosch Rexroth – Select Pump Configurations

In certain Doosan models and replacement scenarios, Bosch Rexroth axial piston pumps are integrated.

Rexroth Pump Series Used

• A10VO Series – Auxiliary and working circuits

• A11VO Series – High-flow, load-sensing systems

These pumps are chosen for precise flow control and global service support.

​

Hydraulic Motor Brands & Models Used in Doosan Equipment

Hydraulic motors in Doosan machines convert hydraulic energy into movement and rotation, operating under high torque and frequent reversals.

​

Travel Motors – Crawler Propulsion

Travel motors must deliver high starting torque and smooth low-speed control.

Common Travel Motor Brands & Models

• Nabtesco / Teijin Seiki GM Series

  • GM24

  • GM26

  • GM28

  • GM30

  • GM38

  • GM40

These motors are widely used in Doosan crawler excavators for stable movement and braking control.

​

Swing Motors – Upper Structure Rotation

Swing motors regulate rotational motion during digging and loading.

Common Swing Motor Brands & Models

• Kawasaki M5X Series

  • M5X130

  • M5X180

  • M5X200

  • M5X250

These motors are selected for smooth acceleration, controlled stopping, and shock resistance.

​

​

Why Correct Brand & Model Matching Is Critical

Using an incorrect hydraulic pump or motor—despite similar appearance—can result in:

• Reduced breakout force

• Jerky swing or slow travel

• Excessive oil temperature

• Premature wear of final drives and cylinders

Multitech India avoids these risks by validating machine model, operating pressure, displacement range, and duty cycle before supply.
