Product Overview
Mechanical room circulation loops and primary transfer skids rely on the Grundfos NB 65-200/189 end-suction pump. Driven by an electric 2.2 kW motor assembly, the pump incorporates an axial DN 80 suction port and a radial DN 65 discharge connection.
Hydraulic volume rating achieves 879 L/Min fluid movement and develops 9.99 m maximum head. The pump housing is cast in EN-GJL-250 iron with cataphoretic electrocoating. Fluid displacement is driven by a stainless steel impeller and a BQQE mechanical shaft seal. Net product weight measures 74 kg.
Drawing a nominal 4.5 Amps, the 2.2 kW motor runs on a standard 415 V three-phase power feed. Operational limits permit media temperatures from -25°C to 120°C under working pressures up to 16 bar. Flanged pipe connections measure DN 80 on the inlet and DN 65 on the outlet.
Enclosure engineering conforms to IP55 protection criteria with Class F thermal insulation. Standard IEC electric drive design requires external motor overload protection. The back-pull-out structural layout permits complete motor and rotating assembly extraction without disconnecting piping headers.
Features
- 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.
- Precision balanced rotating components reduce hydraulic noise and mechanical shaft deflection.
- Renewable casing wear rings retain pump efficiency and avoid direct volute casing wear.
