Rotary disc pump
DCFirst Claim
1. A rotary disc pump for pumping fluid materials, comprising:
- a housing having a front wall, a back wall and peripheral wall joining said front and back walls forming a chamber with a generally coaxial inlet in said front wall and a generally tangential outlet formed in said peripheral wall;
an impeller mounted co-axially within said chamber and comprising a shaft mounted in said back wall of said housing and having an outer end extending from said housing and an inner end within said chamber, at least a first circular disc mounted on the inner end of said shaft, at least a second disc mounted in axially spaced relation to said first disc and having an opening in the center thereof; and
a converging member extending co-axially of said shaft from said first disc converging toward a point at least one half the distance to said second disc; and
a helical fin formed on an outer surface of said converging member.
