|The Allenair pumps are designed around our tandem cylinder design joining two cylinders together with a common head and rod. The total pump unit is divided into two sections; the drive section and the pump section. By utilizing a four-way valve to operate the drive cylinder, the common rod and pump piston will move in unison, creating suction on the up stroke and pressure on the down stroke. An example of this action is that of a syringe.|
