Product Description

The VIO100 gear pump is a replacement pilot hydraulic gear pump specially designed by GVO for the Yanma VIO100 small excavator. It is responsible for supplying oil to the entire pilot hydraulic circuit and transmitting the pressure of the control valves. It is the source of oil pressure that enables the control handle, distribution valve, and rotation braking hydraulic circuit to function. 

The pump body shell is formed by casting a high-strength alloy metal as a single piece. The standard four-hole flange installation end face, spline drive tooth shaft, and oil inlet and outlet structure strictly match the size specifications of the original factory parts. All installation hole diameters, shaft head teeth, and oil port positions are fully compatible with the base of the original vehicle. During maintenance and disassembly, it can be directly installed in place without the need for grinding, modifying the oil circuit bracket and oil pipe joints, which significantly shortens the labor time for replacing hydraulic components of the excavator and is very suitable for maintenance technicians to quickly complete equipment emergency repairs, reducing the downtime loss of construction machinery. 

The wear-resistant side plate and pressure-bearing pad in the pump chamber are made of wear-resistant composite materials, which can resist the continuous scratching caused by fine impurities in the hydraulic oil. The position of the rotating shaft is equipped with a high-temperature-resistant skeleton oil seal and a buffer sealing gasket, which can withstand the long-term high-temperature scouring of the pilot hydraulic oil. In the continuous operation environment of the construction site, the oil seal is less likely to suffer from hardening, cracking, and leakage, ensuring the overall sealing performance of the pump body and eliminating the problem of unstable pressure caused by oil leakage, oil intake, and air intake from the pump head.
