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: 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.

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.

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.
Abstract translation: 移动喷雾分配器包括流体循环系统和加热单元。 流体循环系统具有能够以高压喷射模式和低压再循环模式从流体容器循环流体并将流体提供给喷雾器的电动泵。 电动泵在低压再循环模式下比在高压喷射模式下更低功率。 加热单元设置在流体循环系统内以将流体加热到目标温度，并且包括初级加热器和升压加热器。 主加热器被配置为在高压喷射模式和低压再循环模式期间都是有效的。 升压加热器与主加热器流体串联，并且仅在低压再循环模式下被配置为有效。
