DRUM PUMPS


Allenair transfer 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 our Valve-In-Head® cylinder as the air motor, the common rod and pump piston will move in unison, creating suction on the lower half of the piston and pressure on the upper half. On the down stroke the check piston moves freely through the fluid in the dip tube.
