Product Overview
Primary heating loops and cooling plant headers integrate the Grundfos NB 32-160.1/172 centrifugal pump. Powered by a 0.37 kW electric drive, piping connects via an axial DN 50 suction port and a radial DN 32 discharge interface.
Hydraulic delivery provides a rated flow capacity of 160 L/Min alongside a maximum head limit of 7.178 m. 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 32 kg.
Electrical input from a 415 V three-phase connection runs the 0.37 kW motor with an operating draw of 0.99 Amps. Permissible media temperatures range between -25°C to 120°C under system pressures up to 16 bar. Flanged line ports measure DN 50 for suction and DN 32 for discharge.
Protective specifications incorporate an IP55 enclosure rating and Class F electrical 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
- 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.
- 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.
