Universal 2 Series - AP (Automotive Paint) - Positive Displacement Pumps

FEATURES

A modification of the Universal 2 positive displacement pump, this pump is manufactured specifically for paint re-circulation in the automotive industry. Features:

  • 316 stainless steel pump body and cover.
  • Exclusive, non-galling Waukesha “88” alloy rotors standard; permits running at tighter clearances and pumping a wide range of viscosities.
  • Rotor/shaft connection sealed from product zone.
  • Mechanical seals standard. Single or flushed double.
  • Up to 500 psi (34.5 bar) pressure capability.
  • Rotor nut designed for extended service without loosening.
  • No bearings in product zone.
  • Larger diameter 17-4 PH shafts in seal area for greater strength and stiffness. Helps eliminate vibration; extends seal life.
  • Heavy duty bearing frame.
  • Double tapered roller bearings on all models. Contribute further to precise rotor position and longer seal life.
  • Silicone free grease lubed bearings for positive lubrication to all bearings over entire speed, temperature and pressure range.
  • Body retaining screws for maintaining mechanical seal contact during inspection.
  • O-ring on inner seal, seals on clean surface as seal moves due to wear.
  • Bearing isolators keep product out of gearcase and bearings.

Benefits:

  • Protects water-borne shear sensitive paints.
  • Pigments are not separated, which can change viscosity and cause color shifts.
  • Aluminum and mica metallic flakes are not damaged, which result in deep rich paint luster, and shiny finish.
  • Color matching between body and components is not a problem.
  • Substantial energy cost savings compared to turbine and piston pumps.
  • Constant flow regardless of system pressure changes, results in high film quality and thickness.
  • Pressure surges eliminated.
  • Minimal heat added to product.
  • Pumps are energy efficient, and easily cleaned, maintained, and repaired.
