Liquiflo’s POLY-GUARD Pump: Metallic Pump Performance – Sealless, Plastic Pump Cababilities

Posted on by Sara Springer

Sealless, Non-Metallic Wetted Parts with Metallic Gear Pump PerformanceLiquiflo Poly Guard Pump

The Liquiflo POLYGUARD has NO metallic wetted parts, a mag-drive coupling with a PFA lined Containment Can and a stainless steel housing lined with PFA.  Poly-Guard combines the chemical resistance of a fluoropolymer with the strength of stainless steel. Max temperatures to 200° F & differential pressures up to 100 psi.

Typical Applications: inorganic acids, difficult to handle bases or salts, Hydrochloric Acid, Ferric Chloride, Sulfuric Acid, Hydrofluoric Acid, Sodium Hypochlorite, Nitric Acid, Sodium Hydroxide and Chromic.

POLY-GUARD Features & Benefits:

  • Internal/external protection against corrosive fluids & harsh environments
  • Strong stainless steel body:
    • Handles pipe stresses & other harsh industrial conditions
  • Fluoropolymer lined for protection against corrosive liquids
    • Exempt from wicking problems associated with fiber-reinforced housings
    • Retains the pressure integrity expected of all metal pumps
  • Internal components: PEEK, Kynar (PVDF), Teflon, Silicon Carbide and TTZ
  • Pulseless flow for metering & transfer applications
  • Temperatures to 200° f
  • Differential pressures up to 100 psi
  • Available removable port fittings including flanges & sanitary ports
  • Self-sintered SiC shafts with exceptional chemical resistance & wear resistance
  • Alloy-C or carbon fiber Containment Cans lined with PFA:
    • “Alloy-C Can” limits eddy current development & subsequent heat generation
    • “Carbon Fiber Can” eliminates eddy currents altogether!
