Frequently Asked Questions

It is a Complete Fluid Section (pump lower assembly). Small external hardware may be reused from your unit per the service manual. Always inspect seats, balls, and seals after installation and replace ancillary items if worn.

Check your sprayer’s exact model designation and serial range. This part fits FinishPro 290 and FinishPro II 295. If your plate or manual lists a different lower-pump part number, use that specified part instead.

Yes—replacing a worn lower assembly typically restores prime, pressure stability, and atomization, assuming the motor, air-assist, gun, and tip are in good condition and properly sized for the coating.

Only standard hand tools and PPE are typically required. Follow the service manual for torque specs and safety steps (pressure relief, lock-out, flushing). If unsure, have a qualified technician perform the swap.

Use coatings recommended for your FinishPro 290 / FinishPro II 295 (fine-finish lacquers, enamels, sealers, etc.). Always filter/strain coatings and confirm tip size and pressure per the coating TDS.
