What are the thoughts of some of you guys on the following:
1-- Clutch pully that stops when Gun is not squeezed so this eliminates the need for an Unloader to go into bypass because the pump has stopped so it doesn't over heat or suffer any wear and tear. My question here would be is this safe for the pump to go from nothing to full tilt when the Gun is activated over and over and is it worth the extra expense for the Clutch Pully since there not cheap. Also do they sell those type pully's for larger then 20 HP engines??
2- Since I maybe building my own Powerwasher for the first time and space may be of a concern what do you guys think about using a gear reducer before the pump so the pump spins no faster then it would from a belt and would this type of set-up be just as safe on a pump for long term use as a belt driven set-up.
3-Lastly how do you figure what size engine as in HP if you were to run lets say like two TSF 2021 GP pumps rated at 8.5 gpm @ 3600psi??
Can you use the formala's for a gas engine GPM x PSI/1100= required hp when installing two pumps to it?? I'm thinking you would do the math for one pump and it would be the same for two. Example for the above pump it would be according to that formula you would need aprox a 28hp engine for the one pump or two pumps to it. Is that Correct?
