What three-phase supply voltage and electrical power rating operate this jet pump?
Operating the three-phase motor on the BG-5 requires a 0.55 kW feed across 380–415 V, 50 Hz, three-phase drawing 1.58 A, built with IP55 weatherproof motor enclosure, Class F insulation.
What horizontal mounting guidelines apply to this self-priming unit with its integrated ejector?
Surface placement on a level horizontal base is recommended for the BG 5, where its integrated venturi ejector manages entrained air pockets.
How much vertical elevation head does this jet unit deliver during operation?
Elevating clean water across domestic runs, the BG_5 provides a peak dynamic head rating of approximately 40.2 m.
What flow delivery volume can this self-priming jet pump generate through its discharge outlet?
Supplying clean water distribution, the BG5 generates a maximum delivery flow of approximately 70 L/Min with Rp 1-1/4" (32 mm) suction and Rp 1" (25 mm) discharge threads.
