TSF type of pumps are made of F46 and F4,etc.The high and low temperature resistance is between -85 to 200, for pumping chemically neutral or strong corrosive liquids( not containing solids) .Materials for parts in contact with the process fluid are all fluorine plastics. The pump structure is perfect, and mechanical sealings have strong ability. This series of pumps have kinds of advantages such as small size, light weight, traffic capacity,  high efficiency, easy installation, Energy conservation, safe and reliable.
Mechanical sealings select new technology of no cooling water bellows mechanical seal, Central static is made of alumina ceramic, using ring action-filled PTFE material. Gasket piece is made of F4.This kind of sealing has strong  sealing and anti-corrosive capacity, long life, Energy conservation. It can be used in the fields for dye industry, chemical industry , drugs manufacture, environmental protection, metallurgy, paper manufacture, Nitric Acid production, Chlor-alkali production, etc .
