DURCO GUARDIAN Magnetic Drive Pumps

ASME (ANSI) Chemical Process Pumps

Flowserve Durco Guardian sealless pump technology offers superior, leak-free performance in the most demanding services. Compliant with ASME (ANSI) B73.1-2001 dimensional standards, the Guardian magnetic drive pump is designed for simplicity and reliability in even the toughest emission-free services.

Metallic sealless magnetic drive pump compliant with ASME B73.1, ASME B73.3 and HI 5.1-5.6 that is designed for applications requiring efficient performance and emissions-free reliability.

  • Optimal performance through a highly engineered internal lubrication flow paths designed to maximize cooling of the bushings and journals
  • Ease of maintenance due to standard and contained back pullout, allowing the casing to stay in-line and piping connections to remain intact
  • Higher process temperature range capabilities with the use of strong samarium cobalt rare earth magnets in the couplings
  • Longer service life resulting from silicon carbide bushings and journals that resist wear and corrosion


  • Flows to: 375 m3/h (1650 gpm)
  • Heads to: 215 m (700 ft)
  • Press. to: 24 bar (350 psi)
  • Temp: to 290°C (550°F)
