RY Series air-cooled heat oil pump / air pump is widely used in heating system with heat transfer media in china for such industrial fields as petroleum, chemical industry, rubber, plastics, pharmacy, textiles, printing and dyeing, road construction and food. It is an ideal circulating pump for hot oil and mainly used for transfering weak-corrosion and high-temperature liquid without containing solid grains, whose working temperature is not higher than 370 degree celsius.

RY heat oil pump is the second generation of our product developed on the basis of digesting foreign oil pumps. Its basic structure is single-stage single-suction cantilever support which has an axial suction inlet and a centrally vertical outlet. It is mounted on the base along with the engine.

RY heat oil pump adopts a double-end ball bearing supoort with the front end using the lubricating oil while the back end using the grease as the lubricant and an oil conduit lying for always keeping an eye on the sealing and the recovery of conduction oil.

The pump adopts self-heating and abstraction of heat structure instead of the traditional water cooling structure which thus featured by a simple and space-effective, fewer operation cost, good performance and reliable operation.

RY hot oil pump has the characteristics: 1. Combines packing seal and mechanical seal; the former has a good adaptability for the thermal state due to using packing with resistance to high temperature while the later ensures the seal performance under high temperature as it adopts the hard alloy with strong mechanical strength and wear resistnace. 2. Adopts the third generation of PTFE for the lip seal, thus getting great performance in the seal performance, 25 times the reliability of the rubber seal and extremely strong resistance to corrosion.
