Product Overview
Building utility headers and central hydronic circuits integrate the Grundfos NB 65-160/165 centrifugal pump. Powered by a 1.5 kW electric drive, piping connects via an axial DN 80 suction port and a radial DN 65 discharge interface.
Fluid transfer capacity reaches 967 L/Min rated displacement and overcomes 7.5 m maximum head. A cataphoretically coated EN-GJL-250 cast iron casing houses the precision stainless steel impeller and BQQE mechanical shaft seal. Total net product weight measures 56 kg.
Fed by a 415 V three-phase line, the drive draws 3.15 Amps nominal current to produce 1.5 kW mechanical power. Permissible media temperatures range between -25°C to 120°C under system pressures up to 16 bar. Flanged line ports measure DN 80 for suction and DN 65 for discharge.
Drive housing protection satisfies IP55 requirements with Class F temperature insulation. The motor requires external overload protection in the electrical control panel. A back-pull-out mechanical design enables service personnel to extract the impeller and drive assembly without dismantling pipe flanges.
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.
