Product Description

The hydraulic pump assembly of GVO brand for the main pump of the SK75 SK75-8 SK70SR-2 excavator is compatible with the SK75 SK75-8 SK70SR-2 model hydraulic pump components. It features high-quality performance.

The products are directly supplied from the manufacturer without any middlemen adding extra prices. The cost performance is far superior to similar products. There is an ample stock of goods in stock, and once you place an order, the order will be quickly processed and dispatched. There is no need for long waiting periods.

The entire machine undergoes strict pressure testing upon leaving the factory, ensuring stable quality. At the same time, we provide comprehensive after-sales warranty, and the technical team will follow up throughout the process. Maintenance inquiries can be responded to at any time.

Product Descriptio

This main hydraulic pump, designed for SK75, SK75-8, and SK70SR-2 small excavators, is the core power unit of the entire machine's hydraulic power system. It adopts the K3SP series variable piston pump integrated structure, integrating the pilot pump and pressure regulating component. The pump body mounting flange, transmission shaft specifications, oil port layout, and regulator interface are all fully aligned. It can directly replace the damaged old hydraulic pump on the equipment without the need to modify the pipelines, brackets, and control circuits. It is a core supporting component for minor excavator major repairs, second-hand equipment refurbishment, and hydraulic fault maintenance.

The pump body main body is cast as a whole using high-strength ductile iron, with a thick and stable structure. It has outstanding resistance to vibration, impact, and deformation. Under the harsh working conditions of long-term vibration and repeated high-pressure impact on the construction site, the pump shell is less likely to develop cracks or deformations. The internal cylinder, piston, flow distributor, swing, and other core friction pairs are made of high-hardness wear-resistant alloy raw materials. They undergo multiple precise grinding processes and vacuum heat treatment hardening processes to significantly improve the wear resistance and anti-tensile damage performance of the components, effectively resisting wear damage caused by impurities in the hydraulic oil. This reduces the probability of leakage inside the pump body. The entire sealing component is made of high-pressure-resistant and aging-resistant fluorine rubber material, which can adapt to alternating high and low temperatures and continuous high-pressure impact in the working environment. It maintains stable sealing effect during long-term continuous operation and avoids oil leakage and oil seepage, eliminating the problems of pressure attenuation and abnormal increase in fuel consumption caused by hydraulic leakage. Each hydraulic pump is tested on a professional hydraulic testing bench before leaving the factory. It is sequentially calibrated for no-load, full-load pressure, flow output characteristics, response sensitivity of the variable regulator, and internal leakage indicators. Only when all parameters meet the standards can it be stored and shipped. This strictly controls product quality and avoids quality risks such as unstable pressure, malfunction of the regulator, and other issues.
