BENEFTIS

• Energy savings
  Compatible with external speed variation
  Optional: CERAM CT coating to improve pump efficiency
• Easy installation
  Cast-iron frame as standard for a more rigid assembly
• Easy maintenance
  Access to rotating parts without needing to remove the motor, bearings or hydraulic connections
  Spacer facilitates removal of the motor
  Sealed bearings lubricated for life
• Pump protection
  Vibration-damping design of rotating pump components (shaft and impeller)
  Option: corrosion-resistant cataphoretic coating
  Very low NPSH for greater suction capacity

DESIGN

• Motor
  Standardised IE2 motor featuring asynchronous technology (IE3 on demand)
• Hydraulics
  Single-stage or two-stage axially split pump, with single or double volute
  Cast-iron or ductile cast-iron, stainless steel or bronze housing mounted on a rigid frame
  Cast-iron, bronze or stainless steel 2D hydraulics.
  Impeller diameter can be adapted to optimise the duty point
