DKV130PDTP-9N03 Hydraulic Pump For XE215D/245D
1. Product Overview
DKV130PDTP-9N03 is a swashplate tandem variable axial piston pump, designed as the main hydraulic power source for XCMG XE215D and XE245D medium crawler excavators.
This dual-pump assembly adopts parallel tandem structure with negative flow control regulator. It provides high-pressure hydraulic oil to drive boom, arm, bucket, slewing and travelling actuators of excavator. High-quality interchange aftermarket pump can directly replace OEM pump for equipment overhaul and maintenance.

3. Working Principle
The engine drives the main shaft and cylinder block to rotate synchronously. The reciprocating movement of pistons completes continuous oil suction and high-pressure discharge circulation.
The negative flow regulator automatically adjusts swashplate tilt angle according to signal pressure from control valve, changes pump displacement and adjusts output flow to match actual load demand. Optimized power matching reduces overflow loss and fuel consumption.
The whole hydraulic system realizes composite actions including excavation, lifting, travelling and slewing of excavator.
4. Core Advantages
1. Professional matched assembly specially developed for XCMG XE215D & XE245D medium excavator, installation size, spline shaft and oil port layout fully consistent with original pump.
2. Precise internal friction pair processing, low internal leakage, maintain high volumetric efficiency under continuous heavy load operation.
3. Mature negative flow control system, excellent power matching with engine, effectively lower hydraulic oil temperature and reduce fuel consumption.
4. High-rigidity cast pump housing, strong anti-vibration and shock resistance, suitable for earthwork, municipal engineering, road construction and quarry operation.
5. Stable flow output, low flow pulsation, smooth excavator composite operation, comfortable manipulation.
6. Plug-and-play replacement without pipeline modification; aftermarket spare pump has shorter delivery cycle than original genuine pump.
5. Application Range
Main hydraulic main pump for XCMG medium crawler excavator:
XCMG XE215D, XE245D
Suitable for earthmoving works, municipal construction, highway engineering, pipeline laying, quarry loading and other construction scenarios.
6. Common Faults & Replacement Suggestion
Typical failures: Insufficient digging force, slow combined movements, high hydraulic oil temperature, abnormal knocking noise, shaft seal leakage.
Thoroughly flush all hydraulic pipelines and replace all hydraulic filter elements before installation. Strictly guarantee hydraulic oil cleanliness to prevent impurities scratching cylinder block, piston shoes and valve plate. Replace complete pump assembly if serious internal abrasion occurs.
