Product Description

The hydraulic pump pre-control pump of the GVO brand's hydraulic power SY135 195 excavator main pump is suitable for various types of hydraulic components.
High-quality pilot pump, direct sales from the manufacturer, prompt delivery, and reliable after-sales service.

Product Description

This gear pump is a specially designed pilot gear pump for the ZAX60, ZX60, EX75, and ZAX70 models of excavators. It is also commonly used as a supplementary oil pump for the hydraulic main pump. It is an indispensable core component in the entire hydraulic control system of the machine. 

The product has undergone comprehensive upgrades in raw material selection and casting processes. The main body of the pump is cast as a single piece using high-strength alloy cast iron, resulting in a higher overall structural density. This effectively reduces the risk of pump shell cracking and deformation under long-term high-pressure conditions. The internal transmission gears are processed using high-precision gear grinding technology, with the gear meshing clearance controlled within a very small tolerance range. This significantly reduces impact wear and internal oil leakage during the gear operation, ensuring stable volumetric efficiency even when the equipment is operating under high load for a long time. 

The key sealing components are made of high-quality rubber materials resistant to oil and high temperatures. They can withstand the high-temperature environment of hydraulic oil, effectively addressing the most common problems of end face oil leakage and shaft head oil leakage in old gear pumps. They can be adapted to various complex and harsh outdoor construction environments with large dust, significant temperature variations, and inconsistent oil quality, such as earthwork excavation, landscaping, and indoor crushing. They can operate stably and continuously in various working conditions, including earthwork excavation, landscaping, and indoor crushing.
