description

11410653 axial variable piston pump serves as main hydraulic power unit for Volvo L150E wheel loader. Driven by the engine, it converts mechanical power into adjustable high-pressure hydraulic energy for boom, bucket and steering hydraulic systems. Built-in load sensing control valve dynamically changes pump displacement. During heavy bucket digging and loading, pump increases flow to maintain boom speed; under light load or idle travel, it reduces displacement to save fuel and lower heat accumulation. Internal plungers, cylinder block, valve plate and slipper assemblies are manufactured from high-strength alloy steel with precision grinding and surface hardening treatment. Cast iron housing adopts stress relief annealing to eliminate casting residual stress, resisting vibration and particle contamination on quarry and construction sites. High-performance FKM fluorine rubber sealing assembly delivers reliable high temperature resistance and anti-aging property, reducing internal volumetric leakage and external oil seepage. Every pump passes full hydraulic bench inspection before shipment, including pressure holding, flow characteristic and load-sensing response test.

advantage

- Load sensing response optimized for heavy loading cycle of Volvo L150E
The load sensing curve is tuned to match L150E loading characteristics. It rapidly builds pressure when bucket cuts into dense material piles and reduces flow automatically during boom holding, cutting power consumption and fuel waste.
- Excellent compound action flow sharing for simultaneous boom lift and bucket curl
Precise flow distribution enables boom lifting and bucket curling to operate at the same time without obvious power conflict, greatly improving loading cycle efficiency for quarry and bulk material yard.
- Reinforced valve plate assembly for frequent impact of heavy shovel work
Optimized valve plate structure improves wear resistance, coping with repeated impact loads generated when bucket strikes hard material during continuous high-volume loading.
- Stable pressure retention for digging compacted soil and rock mixture
Strong pressure holding capability avoids pressure drop when digging compacted mixed material, maintaining stable breakout force for heavy-duty excavation tasks.
- Optimized internal flow path to reduce pressure pulsation and system vibration
Refined internal flow channel design lowers pressure fluctuation during variable displacement adjustment, reducing vibration transfer and protecting seals of boom and bucket cylinders.

FAQ 

Q1: Which machine does 11410653 plunger pump fit?
A1: This hydraulic plunger pump is designed for Volvo L150E wheel loader, acting as main hydraulic pump for boom and bucket operation. Confirm machine serial number before purchase.

Q2: What hydraulic functions does this pump support?
A2: It provides high-pressure hydraulic oil for boom lifting/lowering, bucket tilt and vehicle steering, to finish material digging, loading and stockpiling tasks.

Q3: What are typical failure symptoms of worn pump?
A3: Typical symptoms: insufficient digging force in compacted material pile, slow boom lifting under heavy load, pressure drop during boom holding, obvious temperature rise during continuous loading, pump abnormal noise and shaft seal oil leakage.

Q4: What inspections should be done before installing new pump?
A4: Inspect boom cylinders, bucket cylinder, multi-way valve and filter elements. Fully flush hydraulic tank and pipelines to remove metal debris. Replace degraded hydraulic oil before assembly.

Q5: Why loader still lacks digging force after pump replacement?
A5: The fault may not come from pump. Check relief valve calibration, stuck valve spool, clogged filter, damaged cylinder seals or trapped air inside hydraulic circuit. Air bleeding must be completed after installation.
