Abstract: A fluid spraying system includes a displacement pump configured to mount to a drive housing. A reciprocating drive is connectable to a pump rod of the displacement pump and includes a connecting rod and a drive link that receives a head of the pump rod. A tightening ring that includes threading is configured to rotate about a cylinder of the pump and shift axially along the cylinder and engage with a bottom side of the drive housing to secure the displacement pump to the drive housing.

Abstract: A pump rod has a head extending from a neck, and the head is received within a drive slot of a drive link. The head includes a projection, and has an area smaller than an area of the head. The projection contacts an inner surface of the drive slot. The drive link may include a projection aligned with a centerline of the drive link. The drive link projection contacts a head of the pump rod. The projections provide a reduced contact area between the pump rod and the drive link, thereby reducing any side-loading on the pump rod and increasing a lifespan of the wear parts.

Abstract: A motor assembly includes a shaft, an electric motor operatively connected to the shaft to drive the shaft in a first rotational direction, a clutch assembly connected to the shaft, and a fan connected to the clutch assembly and configured to supply the electric motor with cooling air. The clutch assembly drives the fan when the electric motor drives the shaft and allows the fan to freewheel in the first rotational direction when the electric motor is not driving the shaft. A method of operating a fan cooled electric motor includes energizing the electric motor to drive a shaft in a first rotational direction using the electric motor and de-energizing the electric motor so that it no longer drives the shaft, allowing the fan to freewheel in the first rotational direction.

Abstract: A clamp is secured to a displacement pump, and the clamp includes an axial ring and a tightening ring. The axial ring is mounted above the tightening ring, and the axial ring is configured to align the displacement pump during mounting and to limit the stoke of a pump rod within the displacement pump. The tightening ring may be tightened such that the axial ring and the tightening ring exert a clamping force on a drive housing, which secures the displacement pump to the drive housing. The tightening ring may receive a projection extending from the drive housing to provide structural support to the drive housing.

Abstract: A displacement pump includes a pump rod having a load concentrating feature extending from the head of the pump rod. The head of the pump rod is received within a slot of a drive link, and the drive link is configured to contact the load concentrating feature. Having the drive link contact the smaller diameter load concentrating feature reduces the misalignment between the driving force and the center of the pump rod and thereby reduces side-loading experienced by the pump rod. The displacement pump is configured to be used in a fluid dispensing system.
Abstract translation: 排量泵包括具有从泵杆的头部延伸的负载集中特征的泵杆。 泵杆的头部被接收在驱动连杆的槽内，并且驱动连杆被配置为接触负载集中特征。 使驱动连杆接触较小直径的负载集中特征减小了驱动力和泵杆中心之间的不对准，从而减少了泵杆所经受的侧向负载。 排量泵构造成用于流体分配系统。
