Product Descriptio

The Komatsu PC1250-7 hydraulic main pump is the core power source for 100-ton mining excavators. Optimized for heavy-duty loading scenarios in quarries and open-pit mines, the machine employs a three-pump linkage OLSS open-center load-sensing hydraulic system. High-flow oil supply supports rapid loading and unloading of ultra-large capacity buckets, ensuring smooth, uninterrupted operation.

1. The pump body adopts an integrated structure of a dual-axial piston main pump and a pilot auxiliary pump. The internal pistons and distribution plate are made of high-wear-resistant alloy material and precision-ground. Synchronous oil supply ensures stable operation during complex movements, allowing for seamless overlapping of digging, rotating, and traveling actions, significantly reducing work cycle time.

2. The entire valve group features built-in pressure compensation, overload protection, and anti-impact valves. Under heavy-duty impacts and prolonged continuous operation in mining, oil pressure fluctuations are minimal, effectively reducing hydraulic oil temperature and minimizing seal aging and leakage. It is suitable for high-intensity working conditions such as quarrying, large-scale earthmoving, and heavy-duty loading.
