Abstract
A method is used to manufacture a plurality of pumps with different performance properties. Each pump can have a pump housing or a pump housing portion for holding gear wheels in engagement. A plurality of identical universal pump blanks can be primary shaped to create a plurality of identical primary shaped pump blanks. A first operative pump can then be created with a first unique performance property, and a second operative pump can be created with a second unique performance property different from the first unique performance property.
Claims12
A method of manufacturing a plurality of pumps, each of the plurality of pumps having a unique performance property, wherein each of the plurality of pumps has a pump housing or a pump housing portion for supportingly holding gear wheels in meshing engagement, the method comprising the steps of:
- A. providing a plurality of identical universal pump blanks;
- B. primary shaping each of the plurality of identical universal pump blanks to create a plurality of identical primary shaped pump blanks, each having a body with:
- i. a base plate with a connecting flange,
- ii. a receiving pocket surrounded by the connecting flange and extending into a first side of the body,
- iii. one or more predefined connection nozzles on a second side of the body opposite the first side of the body and opposite the receiving pocket,
- iv. one or more mounting spigots on the second side of the body and adjacent to the one or more predefined connection nozzles, and
- v. an oversize defined in or around the receiving pocket;
- C. creating a first operative pump by:
- i. machining the respective oversize of a first one of the primary shaped universal pump blanks to achieve a first unique performance property for the first operative pump, and
- ii. assembling the first one of the primary shaped pump blanks into the first operative pump without machining the one or more connection nozzles and the one or more mounting spigots;
- and
- D. creating a second operative pump by:
- i. machining the respective oversize of a second one of the primary shaped universal pump blanks to achieve a second unique performance property for the second operative pump the second unique performance property being different from the first unique performance property of the first operative pump,
- ii. drilling through the one or more predefined connection nozzles to form one or more passages from the second side of the body into the receiving pocket,
- iii. machining the one or more mounting spigots to form one or more mounting spigot connection points,
- iv. securing a check valve to the one or more mounting spigot connection points and the one or more passages, and
- v. assembling the second one of the primary shaped pump blanks and the secured check valve into the second operative pump having different performance properties and functionality than the first operative pump.
