ABSTRACT:
The pump has an impeller with a retractable component, which, when moved, exposes more or less of the impeller blades, thereby varying the pumping action. The pump has rotor and stator sleeves with complementary tapered surfaces, in which a groove conveys barrier liquid towards the impeller. A piston and cylinder receives the liquid thus conveyed. The pressure of the liquid is controlled by a pressure regulator. A spring biasses the moveable impeller blades one way, and the piston and cylinder oppose that force, whereby the exposure of the impeller blades can be controlled.
