Abstract
A device for pumping fluid such as paints, sealants, caulks, and polymers made of a rotor assembly and a pump body. The rotor assembly contains at least one laminar flow element arranged in such a manner as to conduct the fluid from inlet to outlet as the rotor spins. The rotor may vary its distance from the pump body. This arrangement provides a rotor with exceptional capacity to pump without damage to the fluid media and to measure the fluid rate at low or high rotational speed with viscosity that can vary. The device also may provide a spray nozzle or nozzles that produce a multiplicity of spray patterns.
