Super Bay Set up

[soapy]

I use 1508 tips at 1200 psi in all my bays. A 25% increase in water volume yields twice as much impingement at any given pressure. So a 1506 tip at 2000 psi will not yield as much impingement as a 1508 at 1000 psi. I charge more than most of my competitors and stay busy. Plus with the higher volume of water I can clean a bay much faster.

Here is a good "Spray Tip Chart" I found on KR's website under "Resource Library"...That shows GPM flow depending on tip sizes and PSI...
You can find a lot of good reference material in the Resource Library....

I've got Cat 5CP2120. Figured I'd Bump up the motor pulley 1 inch. The Pump Pulley si pretty much at max to fit the Pulley cover. Soon as I did it I started tripping the starters. Found the gauges weren't reading right and the pressure regulators may need some attention as well. Got some work to do. If I backed off the pressure to about 1300 PSI the motors pulled about 10% below the rating plate amperage.

Earl,
With 1800 rpm motor:
4” motor pulley
8” pump pulley
the pump is operating at 900 rpm.

With a 5” motor pulley the pump is running at 1,125 rpm.
Cat’s spec for max rpm is 950.

Here's a Cat Pumps "Quick Reference" chart to help with motor pulley selection.

Earl, you must have something weird going on if you can't get above 1300 PSI without tripping the starter. I set up a separate 5CP2120W to wash down the lot using a 3HP motor with a 5" pulley and could run it at 1800 PSI with a 2508 tip. I started out at 2000 but that would trip the thermal overload after a few minutes. 1800 was right at the FLA rating of the motor.

Yep, It was a bad gauge . Pressure was really at about 2000PSI!

Price differential? Since I am at $2.50 was thinking of going to $3.00 which is a 20% premium.

One of my closest competitor is only a 25 cent premium.
