A sterile liquid pump, having replaceable single use components, with a first and second chamber, and a gas valve assembly to selectively communicate gas pressure and vacuum with the chambers, and a resilient tubing liquid manifold loop with a sequence of four ports located within a manifold receiver that supports four pinch actuators aligned to engage and selectively pinch-off flow through the manifold between adjacent pairs ports, and, a controller that operates the valve assembly to alternatingly couple pressure and vacuum to the pump chambers, and that also operates to alternatingly actuate pairs of the pinch actuators to sequentially pump fluid from pump chambers under gas pressure, and through an opposing pair of ports in the resilient tubing manifold.

Sterile liquid pump with single use elements

An interlock assembly for a door latch mechanism of a door in a container for bulk material that has an interior lined with a membrane for holding fluid. The interlock assembly includes a plunger in an aperture formed through the door, which moves between an extended position, where the plunger extends into the interior of the container, and a locked position, where the plunger is urged outwardly from of the interior of the container. A spring is positioned to apply a force to urge the plunger to the extended position. A lock member is connected to move with the plunger between the extended position and the locked position. The spring force is selected to enable the membrane, under static pressure of fluid within the container, to urge the plunger to the locked position, thereby engaging the lock member to interlock against operation of the door latch.

A level indicator for a container that is lined with a membrane for holding fluid, and which has a wall with an aperture formed through it. A frame is attached to the container wall adjacent to the aperture. A plunger is engaged with the frame, and moves between an extended position, where the plunger extends through the aperture and into the interior of the container, and a retracted position, where the plunger does not substantially extend into the interior of the container. An elastic member between the frame and the plunger urges the plunger to the extended position. A visual indicator is driven by the plunger between an indicating position and a non-indicating position. The force of the elastic member is selected to enable the membrane, under static pressure of fluid within the container, to urge the plunger to the retracted position.
