Features & Benefits
  • Fully enclosed impellers for high efficiency, low NPSHr applications
  • Modular configuration of either bare shaft end or close-coupled design
  • Shaft sealing options are single or double acting mechanical seals or magnetic drives
  • Hastelloy, ceramic and high efficiency containment shells for demanding magnetic coupled applications
  • Back pull-out design allows removal of rotating element without removing casing, piping or motor
  • Ceramic Canister 1:1 exchange with standard and high efficiency Hastelloy shells
  • Samarium Cobald magnet life extended by temperature limits up to 350°C (662°F) and reversible torque within the allowed temperature range
  • Continues operation at 10% BEP due to low flow
  • Process fluid is mechanically sealed from leakage via an optional additional containment shell
  • Lower total cost of ownership due to high efficiency and low NPSH hydraulics
  • No maintenance necessary when using the SSiC bearing
  • Easy alignment and true back pull-out design with closed coupled assembly
