ATB CD 200L2-2 Y3 Motor with Dickow NCL 80/200 Pump

This industrial pump-motor assembly pairs a 37 kW ATB CD 200L2-2 Y3 electric motor with a Dickow NCL 80/200 centrifugal pump, offering reliable fluid transfer in environments requiring explosion protection (Zone 1). The ATB motor, built by ATB Nordenham GmbH, features IE3 efficiency (93.8%), an IP55 enclosure, insulation class F, and is certified to PTB 03 ATEX 1031 X standards for Ex e IIC T3 Gb protection. Operating at 2955 RPM, the motor is thermally protected with PTC sensors (145°C) and suitable for frequency-controlled speed operation between 300–3000 RPM.

Coupled to this motor is the Dickow NCL 80/200 centrifugal pump, delivering a flow rate of 44.3 m³/h at a head of 17.4 m, driven at 2900 RPM with an efficiency of 47%. The pump’s 18.2 kW power requirement matches seamlessly with the motor’s rated output, ensuring reliable and safe operation in process industries involving flammable fluids or vapors.
