NKM-GE 40-200/219/A/BAQE/1,5 /4 M MCE15/C IE3

Enbloc electric centrifugal pumps with coupling, designed for a wide range of applications such as:
- Circulation of hot water for heating systems.
- Circulation of cold water for air conditioning.
- Circulation of cold water for cooling.

Highly versatile pumps thanks to the use of the MCE/C inverter, to guarantee performance able to automatically adapt to the various system requirements, while maintaining constant differential pressure.

Pump construction characteristics

Spiral single-stage body in cast iron according to DIN-EN 733 (formerly DIN 24255), cast iron support, flanges according to DIN 2533 and DIN 2532 for DN 200.
Cast iron impeller, sealed and dynamically balanced with compensation of the axial thrust via balancing holes, operating (on request) on interchangeable wear rings.
Pump shaft in AISI 304 stainless steel.
Seal: standardised mechanical seal according to DIN 24960 in carbon/silicon carbide with O-rings in EPDM.

Motor construction characteristics

Asynchronous, closed motor cooled by external ventilation, construction design B3/B5, 2 poles for NKP-GE and 4 poles for NKM-GE.
Rotor mounted on generously sized ball bearings to ensure silent and durable operation.
To protect the motor it is advisable to use remote overload cut-outs in compliance with statutory regulations.
In the case of liquids with greater density than water, the motors must be proportionally sized with adeguate power.
Construction according to standards: CEI 2-3
Protection rating: IP 55
Insulation class: F
