Product Overview
Mechanical basement utility headers and chilled water loops rely on the Grundfos NB 80-315/334 centrifugal pump. Driven by an electric 22 kW motor assembly, the pump incorporates an axial DN 100 suction port and a radial DN 80 discharge connection.
Operational flow delivery attains approx. 3016 L/Min maximum throughput and develops approx. 40.3 m maximum head elevation. The pump housing is cast in EN-GJL-250 iron with cataphoretic electrocoating. Fluid displacement is driven by a stainless steel impeller and a BQQE mechanical shaft seal. Net product weight measures 310 kg.
Running on three-phase 415 V power, the unit draws 42.2 Amps rated running current for 22 kW power. Operational limits permit media temperatures from -25°C to 120°C under working pressures up to 16 bar. Flanged pipe connections measure DN 100 on the inlet and DN 80 on the outlet.
Drive housing architecture conforms to IP55 ingress criteria and Class F winding insulation. Standard IEC electric drive design requires external motor overload protection. The back-pull-out structural layout permits complete motor and rotating assembly extraction without disconnecting piping headers.
Features
- Balanced impeller geometry and shaft construction reduce operational vibration throughout duty range.
- Volute casing design incorporates integral base feet for direct mounting to concrete plinths.
- Internal wear rings retain hydraulic clearance tolerances throughout long service cycles.
- Solid stub shaft supported by sealed ball bearings carries axial and radial loads.
- Standard PN16 flanged port interfaces align with EN1092-2 heating and cooling headers.
- Totally enclosed fan cooled IEC motor rated for S1 duty cycles in ambient environments up to 40°C.
- Service-friendly back-pull-out layout enables rotating element servicing without removing pipework.
