NMM Series

Mono-block Centrifugal Pumps

Description :


  • NMM series pumps are single stage, end-suction, mono-block type centrifugal volute pumps.They are standard standart production wiyh enclosed impeller and mechanical seal.
  • Basic dimensions and flow rate EN 733 (DIN 24255) are compatible with proposed values.
  • The thrust (axial force) acting on the motor is compensated by means of the abrasion gasket and balancing holes.
  • Motor and pump are two separate components and there are two shafts. The motor shaft is joined to the pump shaft by a special clamp. In the case of motors with power over a certain value the pump and the motor shafts are joined by seperate rigid coupling.
  • Maintenance - repair processes are very easy due to the back pull-out design.
  • Effective use of common parts in the design of the NMM series facilitates spare parts acquisition and delivery times.
  • Standart asynchronous motors are used for propulsion.
  • In NMM pumps shaft leaking in prevented with a mechanical seal. All radial and axial thrust forces are supported by the motor bearing. 


• Water supply and pumping centers.

• İrrigation, sprinkling, drainage processes.

• Tank systems

• Hot - cold water circulation and cooling system

• Pumping of condensed water

• Swimming pool water circulation.

• Industrial and domestic fluid pumping processes

• Marine applications.
