Abstract
The present invention provides a miniature liquid transfer pump. The pump has a housing that includes first and second blocks joinable to form a leak-resistant impeller chamber with a drive shaft aperture, an inlet and an outlet. An impeller is located in the impeller chamber and a micro-motor with a drive shaft extending therefrom is mounted to the housing. The drive shaft on the micro-motor passes through the drive shaft aperture and engages the impeller. The micro-motor drives the impeller to draw liquid through the inlet and eject the liquid through the outlet.
