API Standard Pump BB5 – DCS (KBDS) / DCD (KBDD)

API Standard Pump BB5 – DCS (KBDS) / DCD (KBDD)

The DCS(KBDS)/DCD (KBDD) is a BB5 type multistage pump with Centerline support and a heavy-duty double casing diffuser design. This pump is suitable for high pressure and high-temperature operations. It is manufactured as per API 610. The range covers a pump head of 2500 m, expandable to higher heads as per requirement. The pump offers a discharge pressure of up to Cl. 2500#. Nozzle orientation as the top-top, side-top and side-side, the direction of rotation is clockwise when viewed from the coupling end. The DCS (KBDS)/DCD (KBDD) pump is suitable for applications in oil refineries and petrochemical industries, boiler feed applications, hydrocarbon and liquid gas transfer applications, petroleum product pipeline booster applications, mine dewatering, oil well, and chemical and process plants. The parts of this pump family are designed to offer maximum interchangeability to serve customer requirements.

Max Head:Up to 2500 Max capacity:Up to 750 m3/hr
