160801020133B002 Expansion Tank Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The Sany 160801020133B002 expansion tank precisely matches the cooling system requirements of the equipment. Its core functions are to contain and compensate for the thermal expansion of the coolant, replenish leaked coolant, stabilize system pressure, expel air from the system, prevent frequent opening of the safety valve, and prevent corrosion of the cooling system. It is a core auxiliary component of the cooling system, ensuring constant temperature operation of the engine and hydraulic system.
This expansion tank is certified by SANY and is compatible with SANY excavators, loaders and other equipment. It is widely used in mining, construction and tunneling operations, solving the pain points of traditional water tanks such as poor sealing, easy leakage and unstable pressure. It avoids equipment overheating failure, reduces maintenance costs and extends the life of equipment and cooling system.
The product adopts a precision stamping and welding integrated process, adhering to SANY’s original factory specifications, and undergoes strict testing throughout the entire process to prevent leakage and deformation. The main body is made of corrosion-resistant cold-rolled steel plate (304 stainless steel optional), treated with rust and corrosion prevention, and features an internal EPDM environmentally friendly rubber airbag (pre-filled with nitrogen, no need for manual refilling), coupled with oil-resistant and temperature-resistant seals. The structure is robust, with strong sealing performance, capable of withstanding harsh outdoor environments and suitable for high-intensity operations. The product structure fits the installation scenario precisely, with standard flanges and overflow/drain interfaces, allowing direct connection to cooling pipes and bolt fixation for convenient and secure installation. The enclosure includes a liquid level observation structure for simple maintenance, strong vibration resistance to withstand high-frequency vibrations during operation, and prevention of loosening and detachment.
