Product Overview
Condenser water transfer and cooling tower circuits operate with the Grundfos NB 32-200/197 centrifugal pump. Coupled to a 0.75 kW motor drive, fluid enters through an axial DN 50 suction port and exits through a radial DN 32 discharge flange.
Hydraulic output attains a Maximum flow volume of approx. 269 L/Min while developing a approx. 13 m maximum head threshold. Constructed with an EN-GJL-250 cast iron volute protected by cataphoretic electrocoating, internal hydraulics feature a stainless steel impeller and BQQE mechanical shaft seal. Net weight is 45 kg.
Running on a 415 V three-phase circuit, the motor assembly draws 1.6 Amps to produce 0.75 kW shaft output. Working tolerances accommodate fluid temperatures spanning -25°C to 120°C at pressures reaching 16 bar. Flanged connections feature DN 50 inlet and DN 32 outlet dimensions.
Environmental protection meets IP55 requirements alongside Class F electrical insulation. Because built-in thermal protection is not included, external motor overload protection must be supplied. Maintenance is streamlined via a back-pull-out arrangement allowing rotating element removal while the casing remains connected to piping.
Features
- 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.
- 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 maximum flow of S1 duty cycles in ambient environments up to 40°C.
