Product Overview
Operating with a 11 kW motor rating, the NB 65-200/162 end-suction centrifugal pump features end-suction axial inlet (DN 80) and top radial outlet (DN 65) connections. The pump is specified for district heating, commercial air conditioning loops, and industrial water distribution.
The pump's hydraulic assembly yields 1500 L/Min rated flow volume and a maximum operational head of 30.84 m. Structural strength relies on an EN-GJL-250 cast iron casing with cataphoresis coating. Internal hydraulics feature a stainless steel impeller and BQQE shaft seal. Physical product weight equals 151 kg.
The NB 65-200/162 pump's 415 V three-phase drive motor delivers 11 kW power output while drawing 21.5 Amps operating current. The pump accommodates circulating fluid temperatures from -25°C to 120°C under working pressures up to 16 bar. Standardized DN 80 suction and DN 65 discharge ports facilitate line placement.
An IP55 enclosure rating protects motor components on the NB 65-200/162 unit, backed by Class F insulation and built-in PTC thermistor sensors. Scheduled maintenance routines utilize back-pull-out access, enabling motor drive and impeller removal while leaving volute casing flange joints intact.
Features
- Back pull-out design allows complete rotating assembly removal including motor, coupling and impeller without disturbing pump housing or connected pipework.
- EN733 and ISO2858 dimensional compliance ensures interchangeability with other standard end-suction pumps across commercial and industrial installations.
- ATEX Zone 1, 2, 21 or 22 certification available for operation in potentially explosive atmospheres (except E-model variants).
- Integrally cast suction and discharge ports with dedicated vent and drain ports provide direct connection points without additional fittings.
- No baseplate or grouting required to maintain correct shaft alignment and vibration levels within Hydraulic Institute standards.
- Cataphoretic electrocoating on cast iron internal surfaces provides barrier protection against oxidative corrosion in hydronic circulation loops.
- Close-coupled configuration eliminates coupling alignment procedures and reduces overall installation footprint compared to long-coupled alternatives.

What specific alloys and surface treatments are engineered into this heavy-duty end-suction pump?
The baseplate-mounted pressure chamber of Grundfos NB 65-200/162 integrates heavy cast iron with a durable stainless steel impeller.
Under peak municipal pumping load, what power rating, electrical line, and current are consumed on site?
Operating across primary headers, NB 65-200/162 draws 21.5 Amps across a three-phase 415 V electrical supply to run its 11 kW motor.
Along primary distribution mains, how extreme can fluid temperatures become under rated working pressure?
Safe fluid circulation across -25°C to 120°C is provided by NB-65-200-162 with maximum system working pressure tolerance up to 16 bar.
Operating on concrete plinth foundations, what maximum dynamic lift is delivered across headers?
Converting rotational motor power into high dynamic lift, NB 65 200 162 delivers a maximum dynamic head of approximately 30.84 m.
Discharging water across multi-building mains, what peak flow rate is sustained on site?
Discharging water into central distribution headers, NB/65/200/162 delivers a peak flow rate of approximately 1500 L/Min.
