Single Stage, End Suction, Centrifugal Volute Pumps NM

  • Main dimensions, compatible w ith EN 733 (DIN 24255) norm.A total of 48 designed pumps available in the series.
  • Single suction with closed impeller, and thrust balanced by means of counter-balancing holes and back wear rings, thus acquiring a dynamic balance.
  • The pump and the motor have a standard connection to the common base plate with a flexible coupling. Maintenance and repair procedures are easily carried out since the pump fixtures can be removed with the volute body remaining intact.
  • Use of extended coupling also enables the removal of the pump fixtures without moving the motor or the volute body.
  • The series has been designed so that parts are easily replaced and standardized. The entire series is made up of only 6 bearings and 10 shaft types, thus simplifying spare parts procurement
