API Standard Pump BB4 – SS(KBSH)/SSD (KBDH)
The SS (KBSH) / SSD (KBDH) s 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 2500 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 #, 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.
- Design and manufactured as per company standard but can meet API 610 requirements as well.
- Multistage pump with ring section diffuser casing design with centerline support to meet high temperature and high-pressure application, especially in BFW application
- Specially designed to meet high performance for superior and extended low-cost operations.
- Easy inspection and repair maintenance of bearings and mechanical seal after removal of coupling spacer only.
- A First stage impeller with double suction is provided in SSD (KBDH) models to improvise NPSH R performance
- High-pressure boiler feedwater applications.
- High-pressure mine drainage applications
- High-pressure applications in water treatment plants.
- Pump as hydraulic power recovery turbine in water treatment plants
