Please have a look at this blueprint I made of what i’m trying to make and tell me if it makes sense to you.
Here is what I have
A DI vessel that is filled with resin.
A water fed pole.
A 50 liter tank.
A trolley to carry the tank.
A 100 psi pump.
I dont have a controller. What is a controller? Just a device that limits the speed of the pump and few other fancy things?
As far as I understand the controller is just there to control the speed of the pump so its not on full blast right?
I contacted a local electronic store which said they could control the speed of the pump with a device that is fairly cheep. Should I just purchase this? Because I cant find these popular controllers here in South Africa.
If you are going with a on demand system you will not need a flow control but if you want a tank based system you will want this one https://shopwindowcleaningresource.com/wcr-pump-controller.html
A pump control will deliver the water from your tank to the brush and save your pump and battery life. There is no replacement in the US market.
I will attach several picture of DIY trolleys so you can see and get ideas. Actual trolleys with tanks are very rare most mount them in there vehicle.
How is the tds over there? Running just di is an option but if its a bit higher you may want to run ro too.
If possible I would leave your system mounted in your truck as your trolley would be around 140 lbs just with the tank. Then you have to consider the weight of your battery, pump, the trolley itself, the di tank… Thats a lot of weight to be pulling around with you. Leave it in the truck and buy extra hose then all you have to do is carry your hose and pole around.
You’re pump is pretty strong. If you’re only using one pole, then 100 psi might be too much. If you get a flow controller thats not too big of a deal but you could save a couple bucks by purchasing a smaller pump.
