1. Product Introduction
This travel hydraulic axial piston pump with OEM part number 1257986 is the core drive hydraulic assembly exclusively for Hamm H3516 and H3520 heavy single drum vibratory compactors.
Adopting closed-circuit hydraulic design, it provides stepless forward, backward and variable speed driving power for the whole machine. Identical flange, oil ports and spline shaft as original pump, plug-and-play replacement without modification. High stable high-pressure output, impact and high temperature resistant, effectively solve common pump faults such as weak driving, machine deviation, abnormal noise, oil leakage and walking failure.
2. Compatible Machine Models
Perfect fit for Hamm heavy single drum soil compactors:
- Hamm H3516
- Hamm H3520
3. Product Key Features
- Standard OEM part No.1257986, fully consistent with Hamm official spare parts catalog
- High-pressure axial piston structure, stable flow under heavy load, smooth and powerful driving without deviation
- Multi-layer composite sealing components, long-term anti-leakage performance for harsh construction sites
- Precision built-in valve group, sensitive stepless speed control same as original factory pump
- Full load pressure and tightness testing finished before shipment, low failure rate and long service life
- Specialized heavy-duty hydraulic drive pump for large soil compaction engineering equipment
4. Application Scope
Widely used in highway subgrade compaction, road reconstruction, large industrial site and earthwork rolling projects.
Damaged travel pump leads to insufficient driving power, unilateral weakness, oil leakage and machine shutdown, causing construction delay. This replacement hydraulic pump can quickly restore normal driving performance of the roller.
5. Our Global Wholesale Advantages
