Abstract: A magnetically driven, linear double diaphragm pump is provided. The pump has a linear magnetic motor that includes a magnetic armature configured inside a cylindrical stator. The stator provides linear translation of the magnetic armature in a back and forth motion. A first pumping section is coupled to a first end of the magnetic armature, and a second pumping section is coupled to a second end of the magnetic armature. As the magnetic armature translates in a first direction, a first diaphragm in the first pumping section is flexed to pump fluid therethrough, and as the magnetic armature translates in a second direction a second diaphragm in a second pumping section is flexed to pump fluid therethrough. A control unit functions to control operational aspects of the motor and pump.

Abstract: A diaphragm pump includes motor that drives an armature in a reciprocating linear motion. A first diaphragm is coupled to a first end of the armature, the first diaphragm positioned in a first pumping chamber and configured to pump fluid into and out of the first pumping chamber in response to the reciprocating linear motion of the armature. A cooling intake valve and a cooling exhaust valve are in operative communication with the first diaphragm, wherein as the armature advances to flex the first diaphragm to decrease a volume of the first pumping chamber, the first diaphragm draws ambient air behind the first diaphragm through the cooling intake valve, and wherein as the armature reverses course to cause the first diaphragm to increase the volume of the first pumping chamber, the first diaphragm forces ambient air out of the first pumping chamber through the cooling exhaust valve.
