A specialized modification of the Universal 2 positive displacement pump, this model is engineered specifically for paint re-circulation in the automotive industry.

Features

  • 316 stainless steel pump body and cover
  • Non-galling Waukesha “88” alloy rotors for tighter clearances and broad viscosity range
  • Rotor/shaft connection sealed from product zone
  • Standard mechanical seals—single or flushed double
  • Pressure capability up to 500 psi (34.5 bar)
  • Rotor nut designed for extended service without loosening
  • No bearings in the product zone
  • Large diameter 17-4 PH shafts for strength and vibration reduction
  • Heavy-duty bearing frame
  • Double tapered roller bearings for precise rotor positioning and seal longevity
  • Silicone-free grease-lubricated bearings for consistent performance
  • Body retaining screws maintain seal contact during inspection
  • O-ring on inner seal maintains sealing as wear occurs
  • Bearing isolators prevent product contamination in gearcase and bearings

Benefits for Automotive Paint Applications

  • Protects water-borne, shear-sensitive paints
  • Prevents pigment separation, maintaining viscosity and color consistency
  • Preserves aluminum and mica flakes for rich luster and shine
  • Ensures consistent color matching between body and components
  • Substantial energy savings compared to turbine and piston pumps
  • Delivers constant flow regardless of system pressure changes
  • Eliminates pressure surges
  • Minimizes heat input to product
  • Energy efficient, easy to clean, maintain, and repair
