Product Overview
Base-mounted hydronic skids and building transfer manifolds deploy the Grundfos NB 80-315/280 end-suction pump. Powered by a 11 kW electric drive, piping connects via an axial DN 100 suction port and a radial DN 80 discharge interface.
Pumping flow rating achieves approx. 2206 L/Min maximum circulation alongside a approx. 27.5 m maximum developed 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 222 kg.
Driven by three-phase 415 V line power, the unit requires 22.3 Amps current to produce 11 kW shaft power. Permissible media temperatures range between -25°C to 120°C under system pressures up to 16 bar. Flanged line ports measure DN 100 for suction and DN 80 for discharge.
Motor shell design features an IP55 enclosure rating alongside Class F 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 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.
- 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.

Does servicing the rotating element require dismantling the plant piping headers?
Pump servicing on the Grundfos NB 80-315/280 leaves facility pipework connected, using a back-pull-out layout for fast mechanical maintenance.
How does this pump maintain fluid containment protect this pump housing against fluid leakage?
Fluid containment in the NB 80-315/280 is maintained by a BQQE mechanical shaft seal, supported by replaceable wear rings that preserve hydraulic clearances.
What piping flange sizes and connection standards are used on this pumping assembly?
The NB-80-315-280 features an axial 100 mm suction port and a radial 80 mm discharge port with standard PN16 flanged connections.
How much motor power and running current drive this pumping assembly?
Operating on a 415 V three-phase supply, the NB 80 315 280 utilizes a 11 kW motor drawing 22.3 Amps with IP55 weatherproof protection.
What fluid movement rate and pumping height does this unit achieve?
Operating capacity on the NB/80/315/280 reaches approx. 2206 L/Min in liquid flow and approx. 27.5 m in dynamic head across duty cycles.
