Beschreibung
Zusammenfassung:	The invention is directed to a packaging machine with a fluid pump assembly of the radial cylinder type, the assembly comprising a plurality of at least three pumps. Each pump has a piston guided in a cylinder, as well as a high pressure port and a low pressure port. A manifold is provided connecting the high pressure ports of a first group of first stage pumps so that the pumps of this first group are operatively connected in parallel, while at least one second stage pump is operatively connected to the first group of pumps in series. The invention is further directed to a method for generating a vacuum in a packaging machine with a fluid pump assembly.
