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 381 L\/Min at a maximum head threshold of 44.4 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 114 kg.\u003c\/p\u003e\u003cp\u003eMotor electrical configuration on the NB 32-200.1\/207 pump requires a 415 V three-phase connection rated at 7.5 kW output power. Operating current measures 14.3 Amps at nominal speed. Liquid temperature ranges extend from -25°C to 120°C under 16 bar pressure. Connection is made via DN 50 inlet and DN 32 outlet flanges.\u003c\/p\u003e\u003cp\u003eMotor security on the NB 32-200.1\/207 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\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\u003cli\u003eBall bearing support arrangement accommodates both radial and axial thrust loads generated during continuous duty operation at rated speed.\u003c\/li\u003e\n\u003cli\u003ePN16 flanged connection ratings on sizes up to and including DN 150 provide elevated working pressure capability beyond standard EN733 10 bar ratings.\u003c\/li\u003e\n\u003cli\u003eO-ring seal between pump housing and cover eliminates leakage risk at the volute-to-cover joint under sustained operating pressures.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003eBulk freight charges apply.
