NKM-GE WITH MCE/P-MCE/C
Enbloc centrifugal pumps with inverter
Standardised centrifugal electronic pumps on base with elastic coupling, designed for a wide range of applications, such as:
MCE/C: Circulation of the hot water of the heating system, of the cold water of the air conditioning and refrigeration systems.
MCE/P: Pressure increase, supply of drinking water and sprinkler and watering systems.
Rotation speed: 1450 - 2900 1/min.
from 1 to 470 m3/h with head up to 72 metres.
Liquid temperature range:
from -10 °C to +140 °C (MCE/C)
from -10 °C to +80 °C (MCE/P)
Pumped liquid: clean, free of solids and abrasives, non-viscous, nonaggressive, non-crystallised and chemically neutral, with properties similar to water.
Installation: normally in horizontal or vertical position, provided that the motor is always above the pump.
Maximum ambient temperature: +40 °C.
Maximum operating pressure:
16 bar - 1600 kPa (for DN 200 max 10 bar).
Insulation class: F.
Flanging: PN 16 DIN 2533.
CONSTRUCTION FEATURES OF THE PUMP
