Product Description

The hydraulic pump pilot pump of the GVO brand for the main pump of the Komatsu PC27MR-2-3 PC30MR-2-3 excavators is suitable for various types of hydraulic components.
High-quality pilot pump, directly sold by the manufacturer without any middlemen profiting from the price difference. Adequate inventory ensures prompt delivery, and the after-sales service is reliable.

Product Description

This gear pilot pump, designed for the micro excavators PC27MR-2, PC27MR-3, PC30MR-2, and PC30MR-3 models, is the core accessory of the entire hydraulic system. It serves as the supplementary oil supply and pilot control power source for the main hydraulic pump, providing stable pilot control oil pressure specifically for small excavators, ensuring the sensitive response of the operating handle and control valve group. It is widely used in landscaping construction, indoor demolition, and municipal operations in narrow spaces, perfectly matching the original vehicle installation dimensions and oil circuit interfaces. It is the preferred accessory for equipment maintenance and replacement.

The product body is made of high-strength aluminum alloy pump body material, combined with precision casting and CNC machining processes. The pump body surface undergoes high-precision grinding treatment. The four-hole installation flange, oil port position, and gear shaft spline specifications fully comply with the original factory standards. No modification is required; it can be directly installed in place. The internal transmission gears are made of high-hardness alloy steel, treated by quenching and grinding, with high tooth shape accuracy and strict meshing gap control. This effectively reduces the internal leakage problem under high-pressure operations. Under long-term continuous operation and frequent start-stop conditions, it can still maintain stable output flow, improving common faults such as sluggish machine operation, handwheel operation jamming, and insufficient pilot pressure, and significantly restoring the overall control feel of the machine. For the dusty and oil temperature fluctuating working environment of micro excavators, this gear pump has optimized the sealing structure. It uses sealing components resistant to high and low temperatures and hydraulic oil corrosion, effectively resisting sealing aging and leakage caused by oil temperature changes, reducing pump body oil leakage and oil seepage faults.
