Sealless, Non-Metallic Wetted Parts with Metallic Gear Pump Performance

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!
