Low NPSH enclosed impellers provide optimal high-efficiency performance over a wide flow range.  

Radial and thrust bearings are available with oil or grease lubrication.  Designs include single row, deep groove ball bearings or duplex thrust ball bearings.

Heat-treated steel shaft limits deflection to 0.05mm (0.002 in), prolonging seal life.

Operating Parameters

  • Flows to 2000 m3/h (8800 gpm)
  • Heads to 170 m (560 ft)
  • Pressures to 21 bar (300 psi)
  • Temperatures from -30°C (-20°F) to 150°C (300°F)
