A rotary filling machine includes a hub member and a hub insert. The hub member includes an internal bore defining an inner surface portion with a plurality of material transfer openings. The hub insert includes a portion disposed within the bore, wherein the portion includes an outer surface portion that includes a plurality of material transfer openings. One of the hub member or the hub insert is rotatable and the other of the hub member or the hub insert is stationary.

Described herein is a flow divider that has two chambers defined by two diaphragms and a spool disposed through the diaphragms. The spool has two tapered nozzles that extend into outlets from each chamber. Within the spool are orifices for providing fluid communication from an inlet to each chamber and dividing the flow. The flow divider generally maintains consistent flow to each outlet even when there is downstream backpressure by being able to move away from the outlet with the increased pressure to further drive the opposite nozzle into the other outlet to reduce the flow at the other outlet to balance the pressure at each outlet.
