ABSTRACT:
A rotary viscosity pump is provided that has a housing and an impeller. The housing has a conical chamber with an outlet at a narrow end of the chamber. The impeller has a conical section with a logarithmic spiral groove along its exterior. The spacing between the housing and the impeller can have either a constant gap or a gap that decreases along the length of the impeller. The depth of the groove can be constant, increase, or decrease in depth along the length of the impeller.
