Pvdf Pumps

PP PVDF -series pumps are specially design for highly corrosive chemicals in which metal pumps are not recommended or in its cost is higher. The PP- series pumps design are single piece molded polypropylene volute casing with semi-open impeller and casing cover to ensure a smooth running performance against corrosion. The high allumina ceramic sleeve protects shaft to any corrosion and abrasion. The GFT or Sic Vs. Ceramic PTFE below Mechanical seal prevents the leakage from the pumps. The Cast Iron heavy duty oil lubricated bearing housing provide maximum strength to pump. The pumps are also available in Mon-block version with compact design. The PVDF series pump thick walled casing liner & back plate is made of PVDF. A large metal insert in PVDF impeller increased mechanical strength.
The PP Series Polypropylene Pumps are also available in monoblock version with compact design.
Application
For handling highly corrosive acids, alkalis, hydrocarbons, effluent, slurries, and other chemicals like; HCL –33%, Dilute H2so4, Caustic solutions ( NaOH ), HF, H3PO4, HN03, Alum, NaoCl, Feso4, CusO4, FeCl3 etc. The pumps are also used in scrubbing of corrosive gases like Cl2, Br2, F2, I2, So2, So3, Co2 etc. as scrubber pump in various chemical industries, in Pickling process in Steel Rolling Mills, Acid circulation in electro plating industries, decaling in boilers, heat exchangers etc.
