End Suction Monoblock Centrifugal Pumps

  • NMM Series are volute, single stage, end suction mono-block type centrifugal pumps. It is produced with closed impellers and mechanical seals as standard.
  • Main dimensions and nominal flow rates are in accordance with the values recommended in DIN 24255 and EN 733.
  • Flanges are in PN 16 pressure class in accordance with ISO 7005-2, DIN 2533 standards.
  • Through the axial force wear ring and balancing holes acting on the impeller.
  • The motor and the pump are two separate units, so, there are two separate shafts. The motor shaft is manufactured as a fitting to the pump shaft. However, for motors above a certain power, the pump and motor shaft are connected by a separate coupling. 

Maintenance-repair operations have become quite easy thanks to the back pull-out design. The use of common components has been effectively implemented while designing the NMM series so that a significant improvement in stock control and delivery time is provided. Standard asynchronous motors are used for the drive. Its zero-shaft leakage is provided with a mechanical seal. All radial and axial forces are carried by the motor bearings.
