ABSTRACT:
A pumping device is provided having a housing comprised of an inlet housing (70) and a discharge housing (98). The inlet housing (70) contains an impeller device (80) that is comprised of a conical structure (82) rotatable about a rotational axis (86). The conical structure (82) has disposed thereon six vanes (84) that extend outward from the direction of the rotational axis (86). Helical vanes (74), (76) and (78) are disposed on the interior surface of the inlet housing (70). The impeller (80) is operable to rotate and force fluid outward against the interior surface of the housing (70), the vanes (74), (78) directing the fluid along the surface. The discharge section then redirects this to the outlet to prevent cavitation.
