Equipped with a 1.5 kW motor drive, the unit features standardized DN 50 axial inlet and DN 32 radial outlet flanged pipe connections.\u003c\/p\u003e\u003cp\u003eLiquid circulation capacity reaches a rated flow volume of 375 L\/Min while generating 12.76 m maximum head limit. The casing body is cast in EN-GJL-250 iron with electrocoated protective finish. Fluid movement is driven by a stainless steel impeller with BQQE mechanical shaft seal. Net product weight measures 45 kg.\u003c\/p\u003e\u003cp\u003eA 1.5 kW drive motor powers the NB 32-125\/115 unit from a 415 V three-phase electrical source, drawing 5.49 Amps nominal current. Working fluid limits handle liquid temperatures from -25°C to 120°C under line pressure ratings up to 16 bar. Standard DN 50 inlet and DN 32 outlet flanged connections support mounting.\u003c\/p\u003e\u003cp\u003eProtective features on the NB 32-125\/115 pump include an IP55 motor enclosure, Class F winding insulation, and internal PTC thermistor monitoring.
