Product details
Replacement Gear Pump for Volvo, Alternative to Part Number 17262775
1. Product Overview
This is a domestically manufactured aftermarket hydraulic gear pump unit, designed as a direct interchangeable replacement for Volvo original part numbers 17262775 and 11148530. It is specially engineered to match Volvo L70, L90, L120, L180, L220, L250 series wheel loaders. This gear pump acts as a key component of the machine hydraulic system, providing stable pressurized oil flow for working hydraulic circuits, steering system and auxiliary functions of the loader. The domestic alternative strictly follows the original drawing dimensions, pressure parameters and port layout, realizing plug-and-play installation without modifying pipelines or mounting brackets, an economical substitute for expensive genuine Volvo spare parts.
Part Reference
- OEM reference part No.: 17262775, 11148530
- Product type: Integrated hydraulic gear pump unit
- Applicable models: Volvo L70, L90, L120, L180, L220, L250 wheel loaders
2. Main Technical Specifications
Item Parameter
Pump type External meshing hydraulic gear pump
Rated working pressure 21 MPa
Maximum intermittent pressure 26 MPa
Rotational speed range 600 rpm ~ 2700 rpm
Sealing material HNBR nitrile rubber (FKM high temperature seals optional)
Applicable fluid ISO VG46, VG68 anti-wear hydraulic oil
Operating temperature -20℃ ~ +90℃
Internal structure Floating side plate automatic clearance compensation structure
Installation Same flange and port position as original Volvo pump
3. Working Principle
Driven by the engine power take-off, the gear pump forms negative pressure at the suction inlet, drawing hydraulic oil from the reservoir. Meshing gears transport oil to the pressure outlet and build system pressure. The continuous oil supply powers the loader’s lifting bucket circuit, steering system and other auxiliary hydraulic functions. The floating side plate design automatically compensates for gear wear, keeping low internal leakage and consistent efficiency during long-term operation on construction sites.
4. Core Advantages
1. Fully dimensional interchangeable with Volvo original 17262775 and 11148530, no adjustment required after installation.
2. Domestic aftermarket production with stable quality, much more cost-effective than original OEM pumps.
3. Floating side plate structure greatly reduces internal leakage, maintaining reliable performance under dusty construction conditions.
4. Precise casting and machining, stable pressure output, effectively solving problems of weak lifting and heavy steering.
5. Complete compatibility across L70, L90, L120, L180, L220, L250 multiple loader models, convenient for spare parts stocking.
5. Application Range
This hydraulic gear pump unit is widely used on Volvo L70, L90, L120, L180, L220, L250 wheel loaders, applied in quarrying, material handling, road construction and earthmoving works, serving as the main supply pump of the whole machine hydraulic system.
6. Failure and Replacement Recommendation
Replace the whole pump assembly if these symptoms appear: insufficient lifting force, stiff steering, oil leakage on shaft seal and mating surface, abnormal grinding noise inside the pump, pressure loss under load.
