API Standard Pump BB3 – KB3S/KB3D

API Standard Pump BB3 – KB3S/KB3D

The KB3S / KB3D is an API BB3 type process pump with near centerline supported heavy-duty axial split casing. This pump’s design offers high performance and efficiency during stringent operating conditions. It is manufactured as per API 610. The KB3S/KB3D pumps come with a pump head Upto 1840 m with an option of upgrading to a higher capacity and head for operations at higher speeds. The pumps operate at a discharge pressure of up to Cl. 2500, nozzle orientation as side-side. The direction of rotation is clockwise from the coupling end. The KB3S / KB3D pump is suitable for applications in oil refineries and petrochemical industries, descaling operations in steel industries, oil wells, petroleum product applications, and chemical and process plants, pipeline applications.

Max Head:Upto 1840 m Max capacity:Upto 1750 m3/hr
