Product Overview
Chiller plant room distribution lines and water exchange circuits integrate the Grundfos NB 50-200/210 centrifugal pump. Powered by a 2.2 kW electric drive, piping connects via an axial DN 65 suction port and a radial DN 50 discharge interface.
Liquid output capacity reaches approx. 892 L/Min fluid volume while overcoming a approx. 15.2 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 82 kg.
Driven by 415 V three-phase power, the unit requires 4.5 Amps rated current to deliver 2.2 kW motor power. Permissible media temperatures range between -25°C to 120°C under system pressures up to 16 bar. Flanged line ports measure DN 65 for suction and DN 50 for discharge.
Drive frame sealing satisfies IP55 protection criteria and Class F winding 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
- Standardized EN1092-2 PN16 flange dimensions match standard commercial and district pipe manifolds.
- High-efficiency IEC electric drive motor maximum flow of S1 continuous operation in ambient conditions up to 40°C.
- Back-pull-out construction allows drive and impeller removal without disconnecting suction or discharge lines.
- Precision balanced rotor and runner assemblies minimize operating vibration across all pump speeds.
- Cast iron volute casing with integral mounting feet absorbs hydraulic forces and pipework stresses.
- Replaceable wear rings retain correct internal hydraulic clearances over long operating periods.
- Solid stub shaft configuration supported by deep groove ball bearings absorbs axial thrust loads.
