  • ConstructionClose-coupled, single-impeller, centrifugal pumps; electricmotor with extended shaft directly connected to the pump.Pump casing with suction and delivery connections with thesame diameter and on the same axis (in-line).

    Connections: Flanges PN 10, EN 1092-2.

    Counterflanges (on request)Sizes FlangesNR,NR4 50, NR,NR4 65 Screwed flanges PN 16, EN 1092-1NR4 80, NR4 100, Flanges for weldingNR4 125 PN 10, EN 1092-1

    ApplicationsFor clean liquids, without abrasives, which are non-aggressivefor the pump materials (contents of solids up to 0.2%).For heating, conditioning, cooling and circulation plants.For civil and industrial applications.When low noise operation is required (n = 1750 rpm).

    Operating conditionsLiquid temperature from -10 °C to +90 °C.Ambient temperature up to 40 °C.Total suction lift up to 7 m.Maximum permissible working pressure up to 10 bar.Continuous duty.

    Motor4-pole induction motor, 60 Hz (n = 1750 rpm).NR4: three-phase 220/380 V.NRM4: single-phase 220 V.

    2-pole induction motor, 60 Hz (n = 3450 rpm).NR: three-phase 220/380 V.NRM: single-phase 220 V, with thermal protector.

    Insulation class F.Protection IP 54.Constructed in accordance with IEC 60034.
