Super Bay Set up

[Earl Weiss]

I see some operators have a "Super Bay " or 3 at a premium price.


They advertise "Regular Bay 1000 PSI - Superbay 1500 PSI.

Who has feedback on this?

Price differential?

Different Pump? If so what?

Different HP Motor? Specifics.

Different Pulley? Specifics?

Different Regulator setting?

I personally think a Super bay would have to be 2500 to 3000 PSI. With a 4006 nozzle to flood the vehicle. We are thinking of doing it in our bay 4 would need a 7.5HP motor. With a Cat 550 pump.

Earl, I set up a Super Bay at one of my washes. I run 1300 PSI through an 06 tip on my regular bays, and 1500 PSI through an 08 on the SB. I wouldn't recommend going much higher than that set-up. As it is, after prolonged use my forearm is pretty fatigued.

Pressure up in the 2500-3000 is an insane amount, and I would think it would be dangerous as hell!

I use Arimitsu 516 pumps on all bays.

The SB pump has to be run faster, so the pulley sizes are different.

I had to change the spring on the MV-580 unloader. Before I swapped out my pump stands, I had Giant unloaders and had to swap from yellow spring/washers to red.

5HP motor works fine.

I charge the same start-up price on all bays, but give less time on the SB.

My signage:

SUPER BAY
MORE WATER - MORE SOAP - MORE PRESSURE

A Cat 530 on a 5 HP motor can run all day at 1800 PSI with an -06 tip with no problem, and I wouldn't go higher than that on a regular SS bay, only a truck bay. I'd recommend a 30" minimum wand to keep someone from accidentally getting their hand in the spray.

We just got a new Karcher washer. It runs at 3000 PSI 5 gal minute. You can wash all day and hand never gets tired. We run the bays at 2000 PSI. with a 1504 nozzle. The only ones I see that won't squeeze the trigger is old people,really old.
We did put two new Vacuums in last summer, we only have two vacuums. One has the regular cuff and the other has a crevice tool. It's 50 - 50 on use. They do about 900.00 a month, Thought it would drop off in the cold and winter but it did not. Has bill accepts on both.
They only average about 50.00 a month, thought they would do better.

Why not make all bays Super, and charge a fair price.. That's what we did.. But 1200 PSI.. Anything more is overkill and most likely dangerous..

A. Competition

B. It's a demand pricing strategy. Slower days people can choose the less expensive option. Busier days they can choose to wait or use a more expensive option.

And the sizes are?

I dunno. Everything I posted was done from memory while sitting in my basement drinking coffee. I will try to check them in the next few days and post it.

Your “Super” bays are delivering 2.8 gpm at 2,000 psi.

Try running #7 tips at 1,200-1,300 psi. The additional 1 gpm will wear you out in relatively short order but, your customers will get a better, and safer wash.

Customers perceive higher volume as high pressure. I frequently hear “You’ve got the greatest pressure.” In reality, it’s the volume they’re feeling…but it takes too long to explain. I just say, “Oh, thanks for coming in.”

How many firemen are needed to hold the hose when the nozzle guy fully opens that fire hose? Ever seen rioters knocked off their feet with the stream from a fire hose? Fire trucks typically boost hydrant pressure to a “mere” 150-175 psi.

A slowly rising river will make everything inside the house wet. A flash flood will knock the house off it’s foundation.

CB80 I'm jealous of your knowledge. I'm picking up what I can along the way from you. Just thought I'd let you know.

 

[2Biz]

CB80 is "Theee Car Wash God"!

 

[cantbreak80]

That’s not true. However, I have been known to pretend…but, just for ceremonial purposes.
Anyway, thanks for the kind words.

We run all of our bays at 1500psi with a Cat 310 pump powered by a 3hp 3 phase motor with a 1505 nozzle.

Pulley size?

CB80, so you put out more water & more pressure? Gonna sound ignorant, but how do I change my psi?
What is the #7 tips, you speak of? What part # would I look up, @ K-R?

 

[MEP001]

#7 would be 2507 or 4007, the 7 is GPM at 4000 PSI. The flow is half that at 1000 PSI.

Breaking it down, 2507....25 is the spray angle, 25°, 07 is the size jet. The bigger the number, the bigger the jet size. I run 2506 at 1200psi...That combination puts out close to 3gpm. You adjust PSI by adjusting the regulator that's attached to the output on the pump. Some are bypassing regulators, some are unloaders...Some have springs, some have special washers that allow you to adjust PSI...Basically the regulator regulates the amount of water that is bypassed which directly affects pressure. Hope that makes sense.
