Abstract
One embodiment of a modular pump includes a cover and a housing that may be engaged with one another during operation. A gearset may be positioned within an internal portion of the housing. If the modular pump is configured as a rotary pump, the gear set may be comprised of an inner gear positioned within a portion of a ring gear. The modular pump may include a spacer positioned between the cover and the housing to allow the modular pump to be configured with gear sets of varying axial dimensions.
Claims5
A modular pump comprising:
- a. a housing having an internal portion wherein said housing is formed with an axial face on a distal surface of said housing;
- b. a first gear set configured to be operably positioned in said internal portion of said housing such that an exterior surface of said first gear set is adjacent to an interior surface of said internal portion, wherein a first gear of said first gear set extends beyond said axial face of said housing in a dimension parallel to an axial dimension of said gear set when operably positioned;
- c. a spacer configured to abut said axial face of said housing, wherein said spacer is formed with a central bore therein, wherein said central bore of said spacer has a size and shape approximately equal to a size and shape of said internal portion of said housing at said axial face, and wherein a thickness of said spacer in said axial dimension of said first gear set is equal to a distance said first gear set extends beyond said axial face of said housing in said axial dimension of said first gear set;
- d. a second gear set configured to be operably positioned in said internal portion of said housing such that an exterior surface of said second gear set is adjacent to said interior surface of said internal portion, wherein an axial dimension of said first gear set is substantially equal to an axial dimension of said internal portion of said pump housing such that a first axial face of said first gear set is substantially flush with said axial face on said distal surface of said pump housing, wherein said modular pump may provide a first set of output fluid flow characteristics utilizing said first gear set and said spacer and a second set of output fluid flow characteristics utilizing said second gear set;
- e. a cover engaged with said housing, wherein said spacer is configured to be positioned between said housing and said cover when said second gear set is operably positioned within said internal portion of said housing, and wherein an engagement between said housing and said cover secures the relative positions of said housing, and said cover.
