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: In one example, a fluid spraying device includes a chassis, a plurality of wheels connected to the chassis, a spray tip assembly connected to the chassis, and a hopper mounted on the chassis. The hopper is in fluid communication with the spray tip assembly and is configured to be oriented in an upright draining position for draining fluid from the hopper. The hopper includes a bottom side, a top side opposite the bottom side and including an aperture configured to receive and drain the fluid, and a side wall extending at an obtuse angle away from the bottom side to the top side adjacent the aperture to facilitate draining of fluid when the hopper is in the upright draining position.

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.
