API Standard Pump BB2 – R2 (KBTS), R2D (KBTD)

API Standard Pump BB2 – R2 (KBTS), R2D (KBTD)

The R2 (KBTS)/R2D (KBTD) is an API BB2 type process pump with Centerline support. This pump with a heavy-duty design ensures high reliability and efficiency during stringent operating conditions. It is manufactured as per API 610. The back pullout feature ensures swift dismantling and assembly. This range of pumps come with a pump head of 520 m, with a discharge pressure of up to Cl. 600#. Nozzle orientation as the and top-top, side-top, side-side. The direction of rotation is clockwise from the coupling end and anti-clockwise is also possible if required. The R2 (KBTS)/R2D (KBTD) pump is suitable for applications in oil refineries and petrochemical industries and chemical and allied industries. The pump is designed to have maximum parts interchangeability.

Max Head:Up to 550 m Max capacity:Up to 1500 m3/hr

  • Design and manufacture as per API 610 standard.
  • Centerline supported heavy-duty design to ensure high reliability under stringent operating conditions
  • After removal of the coupling, spacer, bearings, and mechanical seals on both sides, the rotating element can be removed without disconnecting suction/discharge piping and the driver.
  • The R2 (KBTS)/R2D (KBTD) pump family is designed to have max. parts interchangeability.

  • Fluid handling in oil refineries and petrochemical industry
  • High temperature and high-pressure critical applications in chemical and allied industries
  • A variety of materials for the construction of the pump and seal flushing plans are available to cater to customer requirements and a wide range of applications.
  • The pumps can also function as hydraulic power recovery steam turbines in chemical and process plants.
