Product Overview
Cooling manifold pumping stations and chiller water skids integrate the Grundfos NB 100-315/279 centrifugal pump. The unit couples a 15 kW drive motor to an axial DN 125 inlet nozzle and a radial DN 100 discharge connection.
Pumping displacement output delivers approx. 3264 L/Min volumetric flow while reaching an upper head of approx. 27 m. Volute casing construction features EN-GJL-250 cast iron with cataphoretic electrocoating, paired with a stainless steel impeller and BQQE shaft seal. Product net weight equals 227 kg.
Connected to 415 V three-phase power, the motor requires 28.7 Amps to produce 15 kW shaft output. Operating limits support liquid temperatures from -25°C to 120°C and maximum system pressures of 16 bar. Flanged pipework attaches via DN 125 inlet and DN 100 outlet ports.
The drive casing features IP55 environmental protection combined with Class F insulation. Standard motor installation requires external electrical overload protection. The back-pull-out design allows complete drive and rotating assembly extraction while leaving the casing secured to distribution pipework.
Features
- 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.
- Balanced impeller geometry and shaft construction reduce operational vibration throughout duty range.
