ABSTRACT:
A centrifugal liquid pump including a housing section having an intake cavity and defining a rotational axis of the pump. An impeller section is in communication with and extends coaxially of the intake cavity of the housing section. An impeller is mounted in the impeller section rotatable about the pump axis. A ramp is formed in the intake cavity of the housing section about the pump axis. The ramp includes an axial slope component such that liquid rotating in the intake cavity will be given an axial component of motion toward the impeller section and a radial slope component such that liquid rotating in the intake cavity will be given a radially inward component of motion toward the pump axis.
