Abstract
An electrically operated pumping assembly for a plural component spray system includes an electric motor () having a stator () and a rotor (). The rotor is disposed coaxially with first and second pumps () and is configured to cause pumping by each of the first and second pumps. The first and second pumps are configured to pump different component materials to an applicator () for forming a plural component spray material. A drive mechanism () is disposed between and connected to each of the rotor and the fluid displacement members () of the first and second pumps. The drive mechanism receives a rotational output from the rotor and provides a linear input to the first and second pumps to cause pumping.
