Sprayer upgrading has never so inexpensive or simple. Ready to install in about 10 minutes, the Pumptec 80835 provides performance up to 3 GPM at 150 PSI. It comes pre-assembled and it's as simple as bolting down the pump, bolting down the control valve, and connecting the tank hoses. Easy to repair too! The only tool needed to work on the Pumptec 80835 is a simple Allen Key.
