Abstract: A disposable positive displacement pump is disclosed. The pump includes a pump housing having head portion and a body, the head portion having one or more fluid passage openings. The pump also includes a rolling diaphragm internal to the pump housing and defining a fluid chamber within the pump housing. The pump further includes a piston drive unit configured to reciprocally drive the rolling diaphragm to move fluid in or out of the fluid chamber. A method of dispensing a fluid is also disclosed.

Abstract: A positive displacement dosing system and method of dispensing a fluid including a plurality of disposable positive displacement pumps. The disposable positive displacement pumps each include a pump body having head portion and a base portion, with the head portion having one or more fluid passage openings. Each disposable positive displacement pump also includes a rolling diaphragm internal to the pump body and defining a fluid chamber within the pump body. The disposable positive displacement pump also includes a piston drive unit configured to reciprocally drive the rolling diaphragm to move fluid in or out of the fluid chamber. The positive displacement dosing system includes tubing connecting the fluid reservoir to the disposable positive displacement pump.

Abstract: Apparatus for filling sterile containers is disclosed which defines an elongated but narrow sterile zone in which a number of operating stations are disposed. An elongated vertical wall is armed by an elongated frame and a cabinet type enclosure cooperates with the vertical wall to define the sterile zone. The plurality of operating stations are disposed in sequential relation over the length of the sterile zone, and an elongated container conveyor is disposed within the sterile zone to convey the containers through the plurality of operating stations. The conveyer is vertically oriented, consisting an endless belt mounted on end wheels that rotate on horizontal axes. Each of the operating stations includes an operating portion disposed within the sterile zone. Actuating means are included for each of the operating stations as well as the elongated conveys, each of which is disposed outside the sterile zone.
