Glass pump, English translated into Glass Pump. Glass pump is a kind of corrosion-resistant pump. Refers to the flow of liquid components are brought into contact with parts made of corrosion-resistant chemical instrument glass pump. Chemical glass pumps are generally centrifugal pumps, pump impeller, vortex chamber, shaft seal cavity and pipette, drain nozzle and other over-current components are made of glass. Suitable for the transport of hydrochloric acid and nitric acid, and the concentration of less than 30 ℃ 60% sulfuric acid, less than 50 ℃ concentration less than 40% sodium hydroxide and potassium hydroxide and other liquid medium. Glass pump temperature -20 ~ 100 ℃, temperature shock value ≤ 60 ℃, the current flow rate of up to 45m3 / h, head up to 25m.
