Construction

Hydraulics

Coupling and Flange usable for motors with pumps, installation dimensions in compiance with NEMA Standards. Built-in non-return valve in the pump head. Oversized intermediate bearing in each stage, specially designed to optimise the shaft bearings. Sturdy cable protection. Optimised hydraulics components fpor achieveing high efficiency. High resistance against corrosion and abrasion, thanks to the qualities of the stainless steel. Easy servicing, thanks to simple dismantling and installation characteristics of the aggregate unit.

Motor

Corrosion-free single-phase AC or three-phase motor with enammeled windings in hermatically cast stator for direct starting. Sealed cast stator, resin-saturated, self-lubricating bearings. Motor cooling is effected by the temperature and flow velocity of the pumped liquid outside of the motor.
