Abstract
A fluid pumping device for use in the petroleum and/or chemical industries includes a cast fluid housing having an inlet to or an outlet from the fluid pumping device, a drain/vent tubular connection extending through the cast fluid housing to communicate with the inlet to or the outlet of the fluid pumping device and a flange adapter sealingly secured to the cast fluid housing. A method of providing a drain/vent tube to structurally communicate with an inlet to or the outlet from a fluid pumping device is disclosed.
Claims9
A fluid pumping device for use in the petroleum and/or chemical industries, comprising:
- (a) a cast fluid housing member having an inlet to or an outlet from the fluid pumping device and having a sidewall thereon;
- (b) a drain/vent tubular connection positioned in said cast fluid housing to engage and communicate with said inlet to or said outlet from the fluid pumping device, with said drain/vent tubular connection exiting as said sidewall;
- and
- (c) a flange adapter member secured to said cast fluid housing and structurally arranged to communicate with said drain/vent tubular connection.
A method of providing a drain/vent tube to structurally communicate with the inlet or outlet of a cast fluid pumping device, comprising the steps of:
- (a) drilling a drain/vent tubular connection in the cast fluid pumping device to engage and communicate with the inlet or outlet therein;
- and
- (b) mounting a flange adapter member to the cast fluid pumping device to communicate with said drain/vent tubular connection to permit release of fluid from the pumping device.
