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.
