Product Description

K3V112DT Hydraulic Pump for SK200-6 EC220D Doosan DX921JCM921 Sumitomo SH200 JS200 R200-7 Excavator

Function

Serving as the core power source for excavator hydraulic systems, our hydraulic main pump is driven by the engine. It converts mechanical power into high-pressure hydraulic power, and delivers pressurized fluid to hydraulic motors to power all working functions including lifting, digging, traveling and slewing.

Type

Axial variable piston pumps are widely equipped on engineering excavators. Medium and large size excavators adopt integrated dual main pumps matched with a rear pilot gear pump.
Dual independent high-pressure oil lines supply the main control valve to enable smooth composite actions, with standard working pressure of 28~35MPa.
The low-pressure pilot pump at the pump tail operates at 3~4MPa with low flow, providing reliable control pressure for operating levers and valve spools.

Internal Parts

Precision piston assemblies rotate synchronously with the main shaft inside the cylinder block and housing to complete oil suction and pressurization.
The adjustable swash plate changes its tilt angle to regulate piston stroke and overall pump displacement.
Controlled by hydraulic feedback, the external servo regulator adjusts the swash plate flexibly. Higher tilt angle increases flow and working efficiency; lower tilt angle saves fuel and secures normal engine operation.
The valve plate isolates inlet and outlet oil passages for stable fluid distribution.

Three Control Modes

Constant power control automatically optimizes pump displacement under varying loads to protect the engine and fully utilize power output.
The advanced LS load sensing system provides on-demand flow and reduces fuel consumption during idling.
The HP pressure limiting protection cuts pump displacement at peak pressure, effectively safeguarding hydraulic pipes and cylinders from damage.

Common Failures

Internal leakage caused by component wear or regulator clogging will slow down machine operation and reduce output power.
Regulator stuck at maximum displacement will lead to engine overload, black smoke and stall under heavy loads.
Excessive internal leakage will raise hydraulic oil temperature abnormally. Air intake or damaged internal parts will generate unusual operating noise.

Maintenance

Regular replacement of hydraulic oil and filters can protect precision parts from abrasion. Always keep suction pipelines sealed to prevent air entry and vibration. Maintain hydraulic oil at the rated level for stable pump operation.
