  • Patent number: 11739739
    Abstract: Non-limiting exemplary embodiments of a pumping system and methods for operating the pumping system in a region of high pressure or a region of high flow are disclosed. The pumping system includes a piston disposed within a piston cylinder, a drive shaft, an eccentric coupled to the drive shaft, a connecting arm having opposing first and second ends, and a controller for controlling the rotation of the drive shaft such that the piston oscillates within a region of high pressure or a region of high flow.

  • Publication number: 20230184235
    Abstract: A pump assembly includes a pump module configured to be supported by a fluid tank and a drive module configured to be supported by the pump module. The drive module is mountable to and dismountable from the pump module. The drive module provides a motive force to the pump module to power pumping by the pump module.

  • Publication number: 20230136204
    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.

  • Publication number: 20230125161
    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.

  • Patent number: 9849475
    Abstract: A mobile spray dispenser comprises a fluid circulation system and a heating unit. The fluid circulation system has a motorized pump capable of circulating fluid from a fluid reservoir in a high-pressure spray mode and a low-pressure recirculation mode, and of providing the fluid to a sprayer. The motorized pump draws lower power in the low-pressure recirculation mode than in the high-pressure spray mode. The heating unit is disposed within the fluid circulation system to heat the fluid to a target temperature, and comprises a primary heater and a boost heater. The primary heater is configured to be active during both the high-pressure spray mode and the low-pressure recirculation mode. The boost heater is in fluid series with the primary heater, and is configured to be active only during the low-pressure recirculation mode.
