Spot free pump Question

[pgrzes]

My pump stand has a Cat Pump(I think its a 390) for spot free delivery to bays. Was thinking of switching over to a sta-rite booster pump. Just wondering if any of you are pumping spot free this way. My automatic uses on to push spot free thru 17 tips on the arch, so I dont see why it shouldnt work for the bays??? Need to shrink down my pumpstand!!
Thanks for any help.

It will work, you just won't get as much pressure. Since you have a 390 it must already have good solenoids.

What are the lines to the bays? I've set up washes with 3/8" OD tubing rated to 1200 psi working pressure, and it has a smaller ID than the usual tubing rated at 250 psi. With 450 psi at the pump there's not a lot of line loss to the bay, but a Sta-Rite booster won't go over 250. If I replaced a 390 in said system I think I'd have to replace the tubing.

My JC pump stand came with a sta-rite booster pump for the ss spot free and the new stand I just bought uses the same pump. I am not sure what the pressure is out to the bays, but I can check. I think I saw a sticker on the gauge that said "not to exceed 195 psi" but I need to confirm.

My sfr uses a procon pump for delivery to the bays, you can come up and see it if you want. Be a good opportunity to have a burger&beer & talk about car wash stuff too.

I have a Dultmeier SFR system that uses a 2 hp Booster pump...It is regulated and max is 200 psi. It could be rated at that pressure based on the tubing they used to the bays. It came with 3/8" nylon rated at 250 psi. I'm sure that is at 70° like most. So there has to be a margin of safety built in. It can get to 140° in the attic! Plus they use Kip Solenoid Manifolds. I don't know how much pressure they can handle, probably another limiting factor. I run it at 150 psi and it seems to get plenty of use at that pressure.

That sticker is on the production pump gauge, not the delivery side. They don't want you to exceed 200 PSI on the membrane housing.

I've done many spot-free delivery systems with a Procon pump, 3/32" orifice (250 PSI) solenoids and 3/8" nylon tubing to the bays, and I set it to 225. It's usually very trouble-free as long as no one puts a check valve at the tank, then at some point they'll start blowing lines when a check valve in a bay fails.

I might have to take a ride up there and take you up on that??? Message me your number.
