150108010013A Composite Pump Set Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

150108010013A is a composite pump set with a special material number from Sany, designed specifically for the SY1250H mining excavator. This model has a large operating load, and the hydraulic system has high requirements for the stability and efficiency of power output. It integrates the core characteristics of high-strength wear-resistant base material, composite linkage structure, intelligent constant pressure control, and anti-vibration sealing protection, and complies with national and industry standards such as GB50265-2022 “Pump Station Design Standard” and GB/T 25638.2-2025[3][6]. It is equipped with core components such as SSY008119457 hydraulic oil tank assembly, pump room pipeline, and SSY009114936 cooling pipeline. It is suitable for open-pit coal mines and metal mines, and can avoid faults such as insufficient power output, pressure fluctuation, and leakage. It is a key original part for ensuring continuous operation of the whole machine in the mine.

Core technical parameters

Model: 150108010013A
Main body material: The pump body is made of 40Cr alloy structural steel with quenching and tempering treatment. The wear-resistant wet end parts are made of high-chromium wear-resistant alloy with a tensile strength ≥1000MPa.
Operating temperature: -30℃ to 160℃
Shape and size: Customized according to the SY1250H pump room space, it has an integrated box structure, regular shape, no burrs or cracks, and the size is precisely adapted to the pump room installation space. The length, width and height are customized according to the original factory assembly standard. The position of the mounting hole is ±0.05mm, which can be directly replaced by the original factory. It perfectly matches the size of the sealing gasket, bolts and pump room pipeline.
Key operating parameters: Working pressure 20-35MPa, meeting the high-pressure power requirements of the SY1250H unit; constant pressure accuracy ≤1mH2O; pressure fluctuation range reduced to ±2Bar; outstanding operational stability; flow rate adaptable to 40-120m³/h; output can be automatically adjusted according to load requirements; average energy saving rate of over 30%; speed adaptable to 1500-2200r/min; variable control technology is adopted to reduce energy consumption; service life ≥8000 working hours; meets the standards for heavy-duty pump sets in mining.
Structural Design: Utilizing a multi-pump composite linkage structure, it integrates the advantages of different pump types to achieve power complementarity and improve output efficiency. A built-in PLC intelligent control system monitors pressure, flow, and temperature in real time, enabling closed-loop control and automatic adjustment of output parameters. The sealing employs a dual structure of mechanical seal and packing seal to prevent high-pressure hydraulic oil leakage, adapting to high-pressure operating conditions. The connection between the pump shaft and bearings uses rounded corners to reduce stress concentration, and reinforcing ribs are installed in key areas to resist vibration and prevent deformation, making it suitable for high-vibration environments in mining.

Core functions and roles

As the “power core” of the SY1250H, its core function is to output high-pressure hydraulic oil to drive the excavator’s three major mechanisms of walking, rotating and digging [5]. It integrates the advantages of multiple pumps to achieve efficient power transmission, and at the same time achieves energy saving and consumption reduction, stable pressure supply, vibration buffering and leakage prevention through intelligent control. It can avoid the machine’s movement jamming and efficiency reduction caused by insufficient power output and pressure fluctuations, extend the service life of the core components of the hydraulic system, reduce maintenance costs, and form the whole machine’s hydraulic power system in conjunction with the hydraulic oil tank, pump room pipeline, cooling pipeline, etc. It is a key power component to ensure stable and efficient mining operations.

Applicable Scenarios

Widely used in the hydraulic system of SY1250H machine, it is adapted to the core link of power output in the pump room, and connects to the SSY008119457 hydraulic oil tank, pump room pipeline, and SSY009114936 cooling pipeline. It undertakes the functions of high-pressure hydraulic oil supply and power transmission[3][7]. It can also be adapted to large mining excavators of the same specifications. It is suitable for open-pit mines and earthwork projects with 24-hour continuous heavy load and harsh working conditions. It is an essential hydraulic core component for equipment manufacturing, overhaul, after-sales maintenance and bulk purchase, which can reduce energy consumption and downtime costs.
