IHF series fluoroplastic lined centrifugal pump

Product Overview
The IHF pump is a single-stage single-suction fluoroplastic alloy chemical centrifugal pump. It is designed and manufactured according to the national standard design and combined with the processing technology of non-metal pumps. The pump has the advantages of corrosion resistance, wear resistance, high temperature resistance, no aging, high mechanical strength, non-toxic decomposition, and wide use temperature. The pump body is made of metal casing lining polyfluoroethylene propylene (F46), impeller and pump cover are all made of metal inserts and fluoroplastics. The shaft seal is mechanically sealed with external bellows.
 
Product Features

The characteristic of the IHF type fluorine plastic centrifugal pump is that the pump structure is advanced and reasonable, corrosion resistance is strong, the sealing performance is strict and reliable, and the work is stable. Low noise and long service life. The temperature of the conveying medium is -85 °C~200 °C, the flow rate is 1.75-200m3/h. The head: 4.5-87m speed 1450-2900r/min
 
Product usage
The pump is widely used in chemical, pharmaceutical, petroleum, metallurgy, electric power, electroplating, pickling, pesticide, paper and other industries in liquid transport, wastewater treatment and acid addition process. The use of any concentration of sulfuric acid, hydrochloric acid, nitric acid, acetic acid, hydrofluoric acid, aqua regia, strong alkali, strong oxidants, organic solvents and other highly corrosive media is one of the most advanced corrosion-resistant equipment.
