Benefits

• Low maintenance costs:
  • Fast and also easy to install thanks to self-centring components (upper casing part, rotor, casing cover)
  • Materials resistant to corrosion and also abrasion
  • Smooth operation with low vibration levels
  • Replacement and also spare parts fit several pump sizes
• Long service life:
  • Sealed and also dry shaft
  • Short bearing distances and also a short shaft
  • Optional impeller wear rings
  • Replaceable shaft protecting sleeve
• High operating reliability:
  • Rigid shaft without threads between the bearings
  • Generously sized bearings (Lh10 = 100,000 hours)
  • Reliable sealing thanks to solid casing split flange
  • Double-entry impeller for axial thrust balancing
  • Also Double volute design
• High flexibility:
  • Drive can be positioned to the left or right of the pump
  • Shaft sealed by gland packing or mechanical seals
  • Various horizontal and also vertical installation options
  • Flanges to DIN or ASME
• Excellent efficiencies and also NPSH values:
  • Computer-optimised impellers
  • Large impeller inlet diameters for optimum suction behaviour
  • Cost-effective replacing of casing and also impeller wear rings
  • Also Vortex-free intake elbow with low energy losses
  • Impeller trimmed to match the specified duty point
  • Also Several hydraulic systems per pump size
