Abstract:

Positive-displacement auxiliary pumping systems for use in pump apparatus of different configurations are disclosed. The positive-displacement auxiliary pumping systems are included in positive-displacement rotary pumps having a casing defining a pumping cavity, an inlet port connected to the pumping cavity, a discharge port connected to the pumping cavity, and a positive-displacement auxiliary pumping port connected to the pumping cavity. Pumping elements move within the pumping cavity of the casing and define a collapsing pocket that maintains fluid communication with the positive-displacement auxiliary pumping port after the collapsing pocket is no longer in fluid communication with the discharge port.

International Classification:

F04B 39/00
F04B 9/00

US Classification:

417366, 417374

Abstract:

Modular pump rotor assemblies having a rotatable driving element and a rotor that is removably connected to the driving element by at least one removable fastener are disclosed. The assemblies also have a rotor support bearing that is disposed between the rotatable driving element and the rotor. The assemblies may have a rotatable driving element that is of a type that is dynamically sealed to a pump housing, or a rotatable driving element that is of a type that is statically sealed to a pump housing, such as for use in a magnetically coupled pump or a canned-motor device.

F04D 13/02
F04D 1/04
H02K 49/10

Abstract:

Rotary devices having a casing and an inner drive portion of a magnet coupling disposed inside of a rotor assembly are disclosed. The inner drive portion and rotor assembly are disposed within the casing and rotatable about a rotational axis. The rotor assembly includes a bushing between the magnets of the rotor assembly and a stationary canister is sealed to the casing and separates an internal fluid chamber within the casing from the inner driven portion. The stationary canister can be of multi-piece or unitary construction and is held in position by a front portion of the casing.
