Pump Lower Replacement For the Airless Paint Sprayers

This pump lower eliminates downtime on the job. When you pump stops working simply unscrew the pump lower and swap out for this part. Inside is a pump repair kit, piston and cylinder. Then you can repair your other part one your own time. This has the 5 piece V-Max packings and a stainless steel rod. The Express Pump will last around 800 gallons while the standard version of the pump lower will last 1200 gallons. This works with the older units. Look at part number 17J552 if you have the newer (2015) version of the Graco unit.
