tell me one please. what is the principle of maintaining pressure behind the outlet valve constant ? is that viscosity of paint against nozzle ? because I have some china diaphragm pump repaired, it looks it is working well, but she cannot maintain output pressure after trigerring the gun to spray. the pressure drops too quickly and then it makes two thick stripes on sides of spray pattern. the pressure builds up ok, it holds that, until trigger is pressed... thank You.

I have a Titan Powrliner 3500 that I just got back from warranty service (Titan replaced the pump) 2 months ago, and it won’t prime. I found a big chunk of dried paint in the pickup tube and cleaned it out and replaced the inlet and outlet valves and it still won’t prime. Thanks for posting this video. I’ll try some of your suggestions.

Figured it out yet? I’m still struggling trying to get one to prime.

Been using diaphragm rigs for over 40 yrs. They have their place amongst piston pumps. You should always have them both for different applications.

We have a couple of Titan line stripers with diaphragm pumps. One has been quite reliable, and the other one just broke down again 2 months after getting it back from warranty service. I’m still on the fence about diaphragm pumps. I’ll take a piston pump or a hydraulic over this any day of the week. When they run, they run very well. When they don’t, they’re difficult to fix.
