Abstract

716,377. Screw pumps. FIBREGLASS, Ltd. Aug. 1, 1952 [Aug. 13, 1951], No. 18997/51. Class 110(1) In a pump having a screw-threaded impeller e working in the cylindrical bore b of a casing a, the impeller is axially adjustable relatively to an inlet port d in the casing. A member j carrying a bearing h adapted to prevent relative axial movement of the impeller spindle g has a screwthreaded connection with the casing a so that by rotating the member j, the position of a plain portion f of the impeller relative to the inlet port d can be adjusted to regulate the pump output. Preferably, a seal k is provided. Alternatively or in addition, a sealing impeller e<SP>1</SP> may be provided. A spill port n may be provided, through which liquid can be discharged from the seal and returned to the inlet port.
