Abstract: A displacement pump is 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 flange projects from a pump body of the pump and a ring projects from the pump body of the pump. A portion of the drive housing is received in a gap between the flange and the ring.

Abstract: A handheld sprayer (10′) includes a fluid module (12′) mounted to a drive module (14′) at a static connection (16′) and a dynamic connection (18′). The static connection (16′) supportably attached the fluid module (12′) to the drive module (14′). The dynamic connection (18′) connects a drive (84) of the drive module (14′) to a pump (24′) of the fluid module (12′) such that the drive (84) can power the pump (24′) by the dynamic connection (18′). The fluid contacting components of the handheld sprayer (10′) are in the fluid module (12′). The fluid module (12′) can be mounted to and dismounted from the drive module (14′) by a sliding motion.

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 piston includes a piston cap, a piston rod body, and a piston head, with the piston cap being removable from the piston rod body. The piston cap includes a cap body and a connecting portion extending from the cap body and away from the piston rod body. The connecting portion includes a neck and a cap head with the cap head connected to an end of the neck disposed opposite the piston rod body. The cap head is wider than the neck. A mounting portion of the piston rod body extends into a receiving portion of the cap body to connect the piston rod body to the piston cap.
