PVDF LINED PUMPS/
PFA / FEP LINED PUMPS

• The development of LINED pumps is based on long term experience. The components were designed to supply with more operational Safety. The robust design of the bearing housing ensures the smooth running of the shaft and increases the life of mechanical shaft seal.
• Linings made of PFA/FEP are an excellent alternative to high alloy, expensive metal pumps.
• PFA is a copolymer Tetrafluorothylene and Perfluoroalkoxythylene. PFA stands for Perfluoalkoxy and has temperature resistance upto 1800 Celcius.
• FEP is a copolymer of Tetrafluoroethylene and Hexafluoroethylene. FEP stands for Flurinated Ethylene Propylene and has temperature resistance up to 1500 Celcius.
• The shaft is so designed to meet the international standards for heavy loads i.e., against open discharge valve, minmum flow rates, maximum impeller diameters and high density.

IMPELLER

Semi-open impeller. A large metal insert in the PVDF / PFA / FEP impeller that greatly increases mechanical strength.

SHAFT SLEEVE

Design is matched to the shaft seal mounting High Alumina Ceramic / Silicon Carbide / Hastalloy B/C, Titanium.

SEALING OPTIONS

• Single Mechanical Shaft Seal of various systems & makes are available.
• Double Mechanical Shaft Seal with Sic/Sic Face Combination along with KALREZ ‘O’ Rings provided with API plan 53 with a perssurized thermosyphon system.
