    Fields Of Applications

    • 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.

    Design

    • NMM series pumps are single stage, end-suction, mono-block type centrifugal volute pumps.They are standard standart production with 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.
