Abstract: A pumping assembly comprises: a motor (24) including a stator and a rotor, the rotor configured to rotate relative the stator on a pump axis (PA); a drive mechanism (24) connected to the rotor, the drive mechanism (24) configured to receive a rotational output from the rotor and convert the rotational output into a linear input along the pump axis to cause pumping of the fluid; and a piston (34) connected to the drive mechanism (26) to receive the linear input and disposed coaxially with the drive mechanism (26) and the rotor, wherein the piston (34) is configured to reciprocate axially along the pump axis to pump fluid.

Abstract: An electrically operated pumping assembly for a plural component spray system includes an electric motor (14) having a stator (88) and a rotor (90). The rotor is disposed coaxially with first and second pumps (26a, 26b) 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 (34) for forming a plural component spray material. A drive mechanism (86) is disposed between and connected to each of the rotor and the fluid displacement members (70a, 70b) 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.
