In one embodiment, a fluid delivery system includes a motor assembly and a fluid pump assembly. The fluid pump assembly is spaced apart from the motor assembly, and at least one of the motor assembly or the fluid pump assembly is movable to change a distance between the motor assembly and the fluid pump assembly. The fluid delivery system includes a flexible linkage that couples the motor assembly to the fluid pump assembly, and is configured to transfer motion from the motor assembly to the fluid pump assembly. Further, the fluid delivery system comprises a linkage tightening mechanism configured to generate a tightening force on the linkage by biasing at least one of the motor assembly or the fluid pump assembly in a direction that increases the distance between the motor assembly and the fluid pump assembly.

Belt tightening mechanism for a fluid delivery system

A fluid sprayer is provided and includes a fluid pump assembly having an outlet path and a motor assembly configured to drive the fluid pump assembly to pressurize fluid. The motor assembly is controlled by a throttle mechanism. The fluid sprayer also includes a fluid pressure control assembly including a mechanical pressure transducer configured to be displaced as a function of fluid pressure in the outlet path. The fluid pressure control assembly is configured to control the throttle mechanism as a function of displacement of the mechanical pressure transducer.

Pressure control for a paint delivery system

Pressure control for a fluid sprayer

Paint spraying equipment having an electric motor, gear reducer and fluid section for pressurizing paint and a pressure control module utilizing a combined fluid manifold and pressure control component mounting frame formed of a single die casting and including an access port for servicing a pressure transducer and further including a paint relief aperture in the cover for directing leakage of paint to the exterior of the assembly.

Pressure control module

Piston paint pump housing

An improved fluid section for piston type paint pumps having the piston made from unplated stainless steel and wherein the seal is a multiple lip type formed of ultra-high molecular weight polyethylene and the seal further includes one or more U-shaped internal stainless steel springs.
