Designed for continuous building service duty, the unit handles clean fluid movement across commercial plant installations.\u003c\/p\u003e\u003cp\u003eHydraulic rating calculations confirm a flow capacity of 1581 L\/Min at a maximum head threshold of 38.78 m. The volute housing is constructed from cataphoresis treated cast iron. Rotor hydraulics feature a stainless steel impeller supported by bronze wear rings. Total net weight measures 148 kg.\u003c\/p\u003e\u003cp\u003eMotor electrical configuration on the NB 50-160\/177 pump requires a 415 V three-phase connection rated at 15 kW output power. Operating current measures 29.1 Amps at nominal speed. Liquid temperature ranges extend from -25°C to 120°C under 16 bar pressure. Connection is made via DN 65 inlet and DN 50 outlet flanges.\u003c\/p\u003e\u003cp\u003eMotor security on the NB 50-160\/177 end-suction pump features an IP55 rated housing, Class F thermal insulation, and PTC thermistor winding relays. The back-pull-out structural geometry permits technicians to remove the motor drive and rotor without dismantling connected suction or discharge pipe headers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-efficiency motor selection is configured to match the specific power supply characteristics, pumping environment and liquid properties of each installation.\u003c\/li\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\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003eBulk freight charges apply.
