Patent GB-2239492-A (GB)
Title: Side channel pump
Inventor: DUSSOURD JULES J
IPC: F04D29/18
Filed: 1990-10-22
Abstract: A side channel pump 14 and an impeller 16 therefor permit the improvement of the net positive suction head of the pump by axially extending the impeller blades 22, 23 in a radially inner portion 25 of the impeller, beyond the ends of the impeller blades 21 in a radially outer portion 24 of the impeller. The extended ends have a blade angle  beta B which is smaller than the blade angle 86 of the impeller blades in the radially outer portion of the impeller for improving suction and the ability of the pump to pump liquids at very low pressures. The blades of the impeller in the radially outer portion of the impeller are formed in a section 18 of the impeller separate from the impeller sections 19, 20 carrying the blades of the radially inner portion of the impeller. This reduces the radial blade depth and makes possible milling blades of the several sections with a cutter. The pump casing may define a block seal (37) (Fig 4), and there may be fewer radially inner blades than radially outer blades with inner blades being aligned with outer blades. <IMAGE>
