    The NB 32-160/163 end-suction centrifugal pump incorporates a 4 kW electric drive motor connected to DN 50 suction and DN 32 discharge flanged piping joints. Designed for continuous building service duty, the unit handles clean fluid movement across commercial plant installations.

    Hydraulic rating calculations confirm a flow capacity of 484 L/Min at a maximum head threshold of 28.3 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 68 kg.

    Motor electrical configuration on the NB 32-160/163 pump requires a 415 V three-phase connection rated at 4 kW output power. Operating current measures 7.82 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.

    Motor security on the NB 32-160/163 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.

    Features

    • Optimised impeller and volute hydraulics deliver unimpeded liquid flow through the pump casing, reducing internal turbulence losses.
    • All stainless steel shaft construction provides improved corrosion resistance compared to carbon steel alternatives in wetted service areas.
    • Mechanical shaft seal can be replaced without removing the impeller, system piping, pump volute casing or drive motor from the installation.
    • Housing, impeller and wear ring use dissimilar material pairings to prevent galling and ensure no sticking elements during extended standby periods.
    • High-efficiency motor selection is configured to match the specific power supply characteristics, pumping environment and liquid properties of each installation.
    • Back pull-out design allows complete rotating assembly removal including motor, coupling and impeller without disturbing pump housing or connected pipework.
    • EN733 and ISO2858 dimensional compliance ensures interchangeability with other standard end-suction pumps across commercial and industrial installations.
