Description/Design
  • Hydraulics:
    • NEMA coupling and interconnector accepts any North American motor
    • Non-return valve installed in pump head
    • Over sized intermediate bearings in each stage, specially constructed to improve the shaft deflection
    • Easily replaceable wear rings and bearings
    • Robust cable protection
    • Hydraulic components improved to achieve high levels of efficiency
    • High resistance to corrosion and abrasion achieved through the properties of the stainless steel
    • Easy to service through simple installation and removal of the unit
  • Motor (Franklin):
    • Corrosion-free single-phase alternating current or three-phase motor with lacquer insulated windings in hermetically encapsulated stator for direct starting
    • Sealed encapsulated stator, resin impregnated, self-lubricating bearing
    • The motor is cooled by the temperature and flow speed of the fluid outside the motor
