Abstract
The purpose of this project was to develop an improved dust sampling pump with an electrical to mechanical energy conversion efficiency superior to that of available equipment. Any increase in efficiency would allow the size and weight of the pump to be reduced. The pump was to operate at 9 liters per minute at 20 centimeters of water vacuum. A prototype piston pump driven by a linear actuator was constructed. However, the efficiency of the pump was only 1.6 percent, which is less than that of conventional air sampling pumps.
