    1.1 INTRODUCTION Ruhrpumpen vertical turbine pumps are normally designed to operate in wells or sumps. The bowl assembly consists primarily of a suction case or bell; one or more pump bowls, and a discharge head.

  • Page 8: Pump Bowls, Impeller, And Wear Rings

    1.2.2 Impeller and Wear Rings Impellers used in Ruhrpumpen turbine pumps are of the enclosed centrifugal or mixed flow type. Sealing of interstage leakage is accomplished by the insertion of wear rings to provide close radial fitting between the bowl and impeller sealing surface. Impellers are mechanically connected to the pump shaft by impeller collets and lock nuts which press the impeller tightly against the collets.

  • Page 9: Discharge Head

    Vertical Turbine Pump Position of the impeller on the shaft is determined by an impeller lock pin. The lock pins are inserted at the plant and provide accurate positioning of impellers on the pump shafts. 1.3 DISCHARGE HEAD The discharge head is a resistant cast part or a steel fabricated structure that holds the pump and the bowl assembly to the base.
