Abstract: A compact fluid transfer pump assembly and method of assembly is disclosed. The compact fluid transfer pump assembly includes a pump enclosure having a pump cavity sized to house a plurality of pump components and an inlet for receiving fluid, a motor enclosure coupled to the pump enclosure having a circular first end spaced by a cylindrical wall having an inner and an outer surface to a circular second end, a motor enclosure cavity formed therebetween within the cylindrical wall, the circular first end having an opening for receiving a motor, the circular second end formed by a bell wall, the motor enclosure removably couplable with a tank and an anti-rotation foot removably coupled with the motor enclosure and extending from the outer surface of the cylindrical wall of the motor enclosure, the anti-rotation foot to assist in coupling the pump assembly with an external fluid reservoir.

Abstract: A fluid transfer pump assembly that includes a motor enclosure assembly that forms a motor cavity sized to receive a motor. The motor enclosure includes a flame path that extends from an interior joint to an exterior joint. The interior joint faces the motor cavity and the exterior joint faces exterior of the motor enclosure assembly. A heat sink is located in the motor cavity of the motor enclosure assembly. A portion of the heat sink abuts the interior joint.

Abstract: An explosion proof motor, pump system, and method is provided comprising a motor housing having a circular first end spaced by a cylindrical wall to a circular second end and a cavity formed therebetween within the cylindrical wall. The circular second end formed by a bell wall. The cylindrical first end and circular second end sharing a longitudinal axis that extends concentrically from the first and second ends. A pump housing having a cavity for nesting for rotational movement a rotor comprising a plurality of blades and vanes. The rotor couples to a motor shaft of the motor during use. The cavity is further formed by the cylindrical wall wherein the cylindrical wall has an inner surface and an outer surface such that the outer surface runs parallel longitudinally about the longitudinal axis and the inner surface runs transversely about the longitudinal axis.

Abstract: A gripper assembly which in one form includes a body, at least one jaw, a longitudinally extending wedge, and a spring. The body has a slot disposed therein and opposed longitudinally extending walls. The jaw is laterally slideable within the slot. The longitudinally extending wedge is fitted along the longitudinally extending wall. The jaw comprises a surface that is engageable with the wedge. The surface of the jaw is slideable along the wedge. And a spring biases the wedge toward the jaw to reduce the running clearance between the two structures.
