Abstract

328,591. Seiffert & Co. Akt.-Ges., F., and Mattern, V. Dec. 31, 1928. Casings; heating.-In a centrifugal pump for boiler feeding, nozzles d are arranged in the diffuser wall between stages to admit steam for preheating the water. The steam enters by the passage a and passes through the nozzles d channels being provided so that it can be admitted on each side of the diffuser. Regulating rings h are provided to vary the size of the nozzles.
