Product Overview
Constructed for fixed foundation mounting in mechanical rooms, the NB 32-160/139 single-stage end-suction pump connects via DN 50 suction and DN 32 discharge ports. A 2.2 kW electric motor provides mechanical power for continuous water circulation across building service headers.
Fluid output parameters show a rated throughput of 381 L/Min and a maximum head limit of 19.46 m. Electrocoating treatment on the cast iron casing limits rust in hydronic loops. The internal rotor holds a stainless steel impeller with bronze wear rings. Unit physical weight is 49 kg.
Operating on a 415 V three-phase power supply, the NB 32-160/139 electric motor yields 2.2 kW output power with a current draw of 7.56 Amps. Media temperature capabilities span from -25°C to 120°C under continuous line pressures up to 16 bar. Flanged ports feature DN 50 suction and DN 32 discharge sizing.
Winding insulation on the NB 32-160/139 motor complies with Class F standards within an IP55 dust and spray resistant motor housing equipped with PTC thermistors. Service procedures benefit from back-pull-out construction, permitting internal rotor disassembly without disconnecting main system pipework headers.
Features
- 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.
- Mechanical shaft seal can be replaced without removing the impeller, system piping, pump volute casing or drive motor from the installation.
- Housing, impeller and wear ring use dissimilar material pairings to prevent galling and ensure no sticking elements during extended standby periods.
- High-efficiency motor selection is configured to match the specific power supply characteristics, pumping environment and liquid properties of each installation.
