API Standard Pump BB4 – SS(KBSH)/SSD (KBDH)

API Standard Pump BB4 – SS(KBSH)/SSD (KBDH)

The SS (KBSH) / SSD (KBDH) an API BB4 type pump with ring section diffuser casing design and centerline supported heavy-duty to offer excellent performance in high-pressure operations. It is manufactured as per company standards but it also meets API(American Petroleum Institute) 610. The SS/SSD pumps come with a pump head of Upto 2500 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 #, with nozzle orientation at side-top and top-top. The direction of rotation is clockwise from the coupling end. The SS/SSD pump is suitable for applications in high-pressure boiler water feed applications, water treatment plants, and mine drainage applications. The pump is designed to have maximum parts with interchangeability.

Max Head:Upto 2500 m Max capacity:Upto 750 m3/hr
