WKB KSB

WKB Vertically suspended, single-casing, lineshaft, diffuser-type pump with integral thrust bearings and discharge through column pipe in accordance with API 610 / ISO 13709 (VS1). Available in single-stage and multistage configurations and with either single or double suction first-stage impeller.

Main Applications

• Processes with critical NPSH conditions in chemical and petrochemical industries
• Condensate transport
• Pipelines and tank farms
• Liquefied gas

WKB Benefits

• Pump head is designed and welded according to ASME code to meet API nozzle load requirements. Suction areas designed for discharge pressure.
• Circular or rectangular soleplate allows easy adaptation to different installation conditions.
• Product-lubricated carbon guide bearings with bearing span below requirements of API 610 ensure low vibrations and reliable operation.
• Oil-lubricated bearings integrated in the pump exceed the life requirements specified by API 610, reducing maintenance costs and work. Bearings located at the motor are not subjected to thrust forces from the pump.
• Seal chamber with optional heating/cooling jacket, designed to API 610 allows installation of any API 682 mechanical seal to meet specific process requirements.
• First-stage impeller designed for enhanced suction performance ensures low NPSH values and a short pump design. Bellmouth with flow guide vanes guarantees low-turbulence operation.
