Product Overview
Secondary cooling water skids and primary chiller manifolds deploy the Grundfos NB 80-160/175 end-suction pump. Powered by a 3 kW electric drive, piping connects via an axial DN 100 suction port and a radial DN 80 discharge interface.
Hydraulic flow capacity provides approx. 2095 L/Min volumetric output while reaching a approx. 9.9 m head limit. 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 84 kg.
On a 415 V three-phase line, the 3 kW motor operates with an electrical draw of 6.23 Amps. 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.
Casing structural layout complies with IP55 ingress requirements and 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
- Precision balanced rotating components reduce hydraulic noise and mechanical shaft deflection.
- Renewable casing wear rings retain pump efficiency and avoid direct volute casing wear.
- Solid shaft assembly with sealed ball bearings absorbs operational hydraulic and radial forces.
- EN1092-2 flanged connections conform to standard PN16 pipework dimensions.
- Continuous duty S1 rated electric drive motor operates in ambient temperatures up to 40°C.
- Back-pull-out layout permits motor and impeller servicing without breaking pipe connections.
- Integral casing support feet provide direct anchoring to plant room inertia bases and plinths.

How are the internal hydraulic components built to resist corrosion?
Casing metallurgy for the Grundfos NB 80-160/175 incorporates EN-GJL-250 electrocoated iron and a precision stainless steel impeller.
Which suction intake and discharge port dimensions connect to mechanical plant pipework?
Pipe connections on the NB 80-160/175 consist of an axial 100 mm inlet and a radial 80 mm outlet meeting PN16 flange standards.
How does this pump maintain fluid containment protect this pump against fluid loss?
Dynamic sealing on the NB-80-160-175 incorporates a BQQE mechanical shaft seal and replaceable wear rings that retain internal clearances.
How do thermal operating limits and working pressure boundaries apply here?
Operating boundaries for the NB 80 160 175 safely accommodate fluid temperatures from -25°C to 120°C and maximum system pressures up to 16 bar.
What volumetric throughput and vertical head does this unit develop?
Delivering approx. 2095 L/Min in volumetric flow and approx. 9.9 m in dynamic head, the NB/80/160/175 adapts across its curve.
