The 2BE series flat-disc liquid ring vacuum pumps were introduced into mainland China from Siemens of Germany by Wuhan Water Pump Factory in 1983. As a joint-operation entity of Wuhan Water Pump Factory, Tonfun Pump Industry took part in the technology introduction and localization simultaneously. After nearly 40 years of technology digestion, absorption and re-innovation, Tonfun Pump Industry has built a unique and complete R&D system for vacuum pumps and compressors.

Its Technology Center is a Hubei Provincial-level Enterprise Technology Center, staffed with 11 engineers and 5 senior engineers. The company maintains long-term research cooperation with the School of Energy and Power Engineering of Huazhong University of Science and Technology and the Institute of Fluid Equipment and Testing Technology of China Jiliang University. It carries out flow field research on liquid ring vacuum pumps and compressors based on CFD, and analyzes design outcomes by adopting advanced CFD technology and gas-liquid two-phase flow theory.

A full lineup of products has been successfully developed, including 2BEP and 2BE5 series vacuum pumps, TFTC, TFAT and TFCL series single-stage and two-stage tapered liquid ring vacuum pumps, as well as TFC, 2BK and 2BG series medium and high-pressure liquid ring compressors.

Having fully mastered the core technologies of flat-disc and tapered liquid ring vacuum pumps, the company has become a large-scale comprehensive manufacturing base for single-stage and two-stage flat-disc & tapered liquid ring vacuum pumps and compressors in China.

It also participates in drafting national and industrial standards for liquid ring vacuum pumps and compressors. Up to now, the enterprise has obtained over 20 national patents. Six patents including A Corrosion-resistant Liquid Ring Vacuum Pump are authorized national invention patents, and fifteen achievements such as Complete Vacuum Pumping Equipment for Condensers of Million-kilowatt Thermal Power and Nuclear Power Units and A Large Two-stage Tapered Liquid Ring Vacuum Pump have been granted national utility model patents.
