151503000102B Return Oil Filter Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The Sany 151503000102B return oil filter is the “core of return oil purification” in hydraulic systems. Installed in the return oil pipeline and connecting the return oil pipe to the oil tank, it adopts a multi-layer composite filtration structure to filter out metal particles, mechanical impurities, and oxidized colloids in the return oil. This prevents impurities from wearing down precision components such as hydraulic valves and cylinders, and buffers impact vibrations during operation. It is specially designed for Sany’s large heavy-duty engineering machinery (such as the SDC120/125 twin-wheel milling machine, 570.5kW power), and can avoid malfunctions such as oil contamination and component wear caused by filter failure and blockage. It ensures equipment operation, improves construction efficiency, is suitable for various heavy-duty projects, and fits the high-efficiency heavy-duty positioning of Sany equipment.
This product strictly adheres to SANY’s original factory standards, employing high-quality glass fiber filter media and a high-strength steel shell in a single integrated process, coupled with oil-resistant nitrile rubber seals. It boasts advantages such as high filtration accuracy, large dirt-holding capacity, impact resistance, and convenient installation. Through precision machining, filtration, pressure testing, and aging treatment, it achieves accurate dimensions, a high degree of fit, and a leak-proof seal. The pleated filter media increases the filtration area, providing strong anti-clogging properties, low initial pressure drop, and rapid impurity interception. Suitable for dusty outdoor environments, it can be directly installed, reducing downtime losses, extending the lifespan of hydraulic components and systems, and lowering maintenance costs. It is a core component for oil return purification.
