Horizontal Centrifugal Non-Metallic Lined Pumps

(M.O.C.: PVDF, ETFE, TEFLON (i.e.FEP, PFA, etc.))

The hi-tech lining process involves high pressure moulding at high temperature to ensure uniform thickness of lining free from cavities, air pockets, cold flows, etc. A unique feature is the dove tail grooves provided on the metal casing and back plate.....

Technical Features

  • The hi-tech lining process involves high pressure moulding at high temperature to ensure uniform thickness of lining free from cavities, air pockets, cold flows, etc.
  • A unique feature is the dove tail grooves provided on the metal casing and back plate.
  • This ensures a firm grip between the metal and lining material.
  • A dynamically balanced, solid moulded, semi open impeller with metallic insert gives mechanical strength and durability.
Technical Features

Casing and Back Plate and Impeller

  • Thick walled casing and back plate is made of PVDF,FEP, PFA Lining.
  • Standard shell of cast iron, cast steel.
  • Semi open impeller.
  • It is one piece, robust construction, dynamically balanced & is provided with back vanes to minimize axial thrust for enhanced bearing life.
