Product Overview
District cooling networks and hydronic distribution stations employ the Grundfos NB 32-200/216 centrifugal pump. Powered by a 1.1 kW electric drive, piping connects via an axial DN 50 suction port and a radial DN 32 discharge interface.
Water movement capacity reaches 320 L/Min rated flow and develops a 12.59 m maximum head parameter. 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 50 kg.
Supply power from a 415 V three-phase source feeds the 1.1 kW electric motor at a rated current of 2.34 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.
Drive housing design features IP55 enclosure protection and Class F insulation standards. 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
- Precision balancing of rotating parts delivers quiet, low-vibration fluid transfer.
- Heavy-section cast iron volute with integral mounting pads provides solid base support.
- Replaceable wear rings protect casing hydraulics and retain designed pumping clearances.
- Solid stub shaft and ball bearing arrangement counteracts operating mechanical stresses.
- Standardized PN16 dimensions per EN1092-2 align with facility pipe headers.
- IEC standardized electric drive rated for continuous S1 operation in ambients up to 40°C.
- Back-pull-out arrangement allows fast access to motor and impeller without disturbing pipework.
