A housing for a double spiral centrifugal pump, comprising:
- a spiral housing defining a flow channel;
- and
- a multi-part rib disposed in said housing to divide said flow channel, said rib including at least two rib parts spaced from each other to define at least one gap therebetween,
- said housing including a housing lip defining an outlet passage,
- one of said at least two rib parts located nearest said housing lip being disposed at a distance from said housing lip to define a gap therebetween, and
- said at least two rib parts consisting of a number n of said rib parts, wherein an angle .tau. between said housing lip and an upstream edge of a first one of said rib parts in a direction of flow is in the range of ##EQU7##
A housing for a double spiral centrifugal pump, comprising:
- a spiral housing defining a flow channel;
- and
- a multi-part rib disposed in said housing to divide said flow channel, said rib including at least two rib parts spaced from each other to define at least one gap therebetween,
- wherein the rib parts are disposed adjustably in the double spiral housing.
A method of manufacturing a housing for a double spiral circulation pump, said method comprising the act of forming a spiral housing defining a flow channel with a multipartite rib disposed in said housing to divide said flow channel, said rib including at least two rib parts spaced from each other to define a gap therebetween.
