The main pump is one of the important hydraulic parts of excavator that drives the vehicle with hydraulic power. It converts kinetic energy generated from the engine to hydraulic energy. With the supplied kinetic energy from the engine, the pump regulates flow rate with displacement of the piston.

• Optimization to DEVELON equipment : manufactured by DEVELON
• Lowest noise level : Employing high rigidity parts.
• Minimized potential leak.
• Highest efficiency.

The main control valve provides independent operation of all the excavator components. It receives hydraulic oil from the main pump and distributes the oil to the hydraulic actuators (travel motor, swing motor, cylinders, etc.).

• High accuracy : Core technologies at global-top level.
• Minimized reject ratio : Total inspection system employed for quality control.
• Fine-tuned operation : Excellent versatility and controllability.

The travel device consists of traction motor and speed reducer, and drives excavator by rotating tracks or wheels. Hydraulic energy is supplied from the traction motor, converted to mechanical energy and transmitted by speed reducer.

• Minimized no. of parts : Saving maintenance cost.
• Enhanced convenience : Shockless function embedded.
• Advanced technology : Anti-cavitation function embedded.
• Quality recognition.

DEVELON Seal Kits use the reliable products only, which have been verified for stable quality. The use of genuine seals with stable quality minimizes problems with cylinder seals, thereby extending the life of cylinders and reducing machine maintenance costs.

• Excellent elongation, rigidity and wear resistance.
• Greater hardness and tensile strength.
• Lower coefficient of friction.
• Excellent thermal resistance, elasticity and restitution.
