The pump is specified for district heating, commercial air conditioning loops, and industrial water distribution.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eAn 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBack pull-out design allows complete rotating assembly removal including motor, coupling and impeller without disturbing pump housing or connected pipework.\u003c\/li\u003e\n\u003cli\u003eEN733 and ISO2858 dimensional compliance ensures interchangeability with other standard end-suction pumps across commercial and industrial installations.\u003c\/li\u003e\n\u003cli\u003eATEX Zone 1, 2, 21 or 22 certification available for operation in potentially explosive atmospheres (except E-model variants).\u003c\/li\u003e\n\u003cli\u003eIntegrally cast suction and discharge ports with dedicated vent and drain ports provide direct connection points without additional fittings.\u003c\/li\u003e\n\u003cli\u003eNo baseplate or grouting required to maintain correct shaft alignment and vibration levels within Hydraulic Institute standards.\u003c\/li\u003e\n\u003cli\u003eCataphoretic electrocoating on cast iron internal surfaces provides barrier protection against oxidative corrosion in hydronic circulation loops.\u003c\/li\u003e\n\u003cli\u003eClose-coupled configuration eliminates coupling alignment procedures and reduces overall installation footprint compared to long-coupled alternatives.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003eBulk freight charges apply.
