Driven by an electric 3 kW motor assembly, the pump incorporates an axial DN 100 suction port and a radial DN 80 discharge connection.\u003c\/p\u003e\u003cp\u003ePumping liquid volume delivers approx. 1745 L\/Min maximum capacity with a maximum head elevation of approx. 10.3 m. The pump housing is cast in EN-GJL-250 iron with cataphoretic electrocoating. Fluid displacement is driven by a stainless steel impeller and a BQQE mechanical shaft seal. Net product weight measures 102 kg.\u003c\/p\u003e\u003cp\u003eDrive motor operation on a 415 V three-phase supply draws 6.23 Amps running current for 3 kW. Operational limits permit media temperatures from -25°C to 120°C under working pressures up to 16 bar. Flanged pipe connections measure DN 100 on the inlet and DN 80 on the outlet.\u003c\/p\u003e\u003cp\u003eProtective casing design meets IP55 ingress specifications alongside Class F motor insulation. Standard IEC electric drive design requires external motor overload protection.
