Product Overview
The NB 32-200/190 single-stage end-suction pump operates on a 415 V three-phase supply rated at 5.5 kW drive power. Built with an axial inlet port (DN 50) and top radial outlet port (DN 32), the unit connects into commercial hydronic heating networks, cooling tower water loops, and facility fluid transfer lines.
Under full duty load, the pump generates 494 L/Min rated flow capacity and reaches a maximum head threshold of 37.84 m. The heavy volute housing uses electrocoated cast iron to resist internal corrosion. A stainless steel impeller rotor assembly with bronze wear rings drives fluid transfer. Net product weight equals 105 kg.
Drive power on the NB 32-200/190 pump comes from a 5.5 kW electric motor operating on a 415 V three-phase electrical connection. Full-load running current measures 10.5 Amps. The pump processes liquid media over temperatures from -25°C to 120°C under line pressures up to 16 bar. Pipe connections use DN 50 suction and DN 32 discharge flanges.
Built with an IP55 rated motor enclosure and Class F insulation, the NB 32-200/190 electric motor incorporates internal PTC thermistor sensors against overheating. Servicing is simplified by the back-pull-out structural layout, enabling complete rotor and drive removal without disconnecting suction or discharge pipe joints.
Features
- Cataphoretic electrocoating on cast iron internal surfaces provides barrier protection against oxidative corrosion in hydronic circulation loops.
- Close-coupled configuration eliminates coupling alignment procedures and reduces overall installation footprint compared to long-coupled alternatives.
- Ball bearing support arrangement accommodates both radial and axial thrust loads generated during continuous duty operation at rated speed.
- PN16 flanged connection ratings on sizes up to and including DN 150 provide elevated working pressure capability beyond standard EN733 10 bar ratings.
- O-ring seal between pump housing and cover eliminates leakage risk at the volute-to-cover joint under sustained operating pressures.
- Optimised impeller and volute hydraulics deliver unimpeded liquid flow through the pump casing, reducing internal turbulence losses.
- All stainless steel shaft construction provides improved corrosion resistance compared to carbon steel alternatives in wetted service areas.
