Product Overview
Chilled fluid pumping stations and condenser return lines use the Grundfos NB 65-160/177 end-suction pump. The unit couples a 2.2 kW drive motor to an axial DN 80 inlet nozzle and a radial DN 65 discharge connection.
Volumetric pumping output attains 1056 L/Min fluid delivery alongside a 8.717 m maximum head rating. 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 68 kg.
The motor mechanism connects to a 415 V three-phase supply, pulling 4.5 Amps rated load current for 2.2 kW. Operating limits support liquid temperatures from -25°C to 120°C and maximum system pressures of 16 bar. Flanged pipework attaches via DN 80 inlet and DN 65 outlet ports.
Physical casing design complies with IP55 standards, featuring Class F motor 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
- 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.
- 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.

How do the housing materials protect this pump during demanding circulation?
Housing metallurgy on the Grundfos NB 65-160/177 utilizes cataphoretically coated EN-GJL-250 cast iron and a stainless steel impeller.
How much electrical power and running current drive this pump drive?
The NB 65-160/177 is driven by a 2.2 kW motor running on a 415 V three-phase supply, drawing approximately 4.5 Amps with IP55 protection.
What mechanical seal type and internal clearances protect this pump housing against fluid leakage?
The NB-65-160-177 utilizes a robust BQQE mechanical shaft seal and replaceable wear rings to prevent fluid loss and preserve internal clearances.
How does the volute layout allow drive maintenance without pipework disassembly?
Extracting the rotating assembly on the NB 65 160 177 requires no pipe disconnection, thanks to its back-pull-out maintenance architecture.
What maximum throughput rate and dynamic head does this pump generate?
Operating capacity on the NB/65/160/177 reaches up to 1056 L/Min in liquid flow and 8.717 m in dynamic head across duty cycles.
