Where to get a water recirculatory system

bangophinx

Does anyone know of any suppliers for water re-circulatory system?

Im thinking of building one myself if i cant get any suppliers. Does any one know where i can source a tank, filter and pump in Ireland?

Thank in advance

In the absence of any details such as sizes, diameters, flowrates, I can suggest some supplier like Smallmans plumbing supplies.

Or else...... RS Radionics have a large inventory, if somewhat a tad expensive and a little harder to navigate.

Thanx Silverbell for the quick reply and apologies for mine being late.

I am looking for a 50 litres tank, a submersible pump capable of variable flow rate of 0 - 2 l/min at a height of 3m above the tank. I want to filter debris formed by my process as i need clear water recirculating; not too worried about composition or impurities just as-long as it is clear.

I will contact Smallmans but i believe their stuff is an overkill. Radionics offer submersible pumps, not so much tanks and filters. Am finding it hard to find solution providers so i guess this will be a DIY project :eek:.

Yeah, as your pressure and flowrates are quite small, this may be even overkill for what you need.

I used these guys for buying a few filters a few years back. I thought they were great. They had a great range, and good prices, even taking to account the customs duty.

You'll have to check for NPT threads, though Flomax in Dublin will get you NPT to BSP adapters. Theres another gang for water fittings is Flomax!! They do both of flexible and rigid plastic piping and tubing that can be used with push in fittings.

You'll get a 50l tank in most plumbing shops, it about the size for a small overflow or header tank. (think on the black plastic rectangle ones), even a 50l barrel would do you, just put a tank connecter inside it to take water off. Do you really need a sumbersible pump? What about a pump attached to the outside of your tank?

If the pump was not variable, you could fit it with a bypass back to the tank, and your main line to your application could be "throttled" by an ordinary gate valve. The pump then chugs happily at part load (cos you have the bypass partially open) and you just draw off what you require at your application. My thoughts so far are all manual control, I'm assuming this is not to be part of a PID loop in which case you'd need an electronically controlled throttle valve of some sort.

Radionics do a nice line of GEMS sensor flow meters, for about 30 euros, or else use a stopwatch and grad cylinder to verify flow rate.

Fitting a bypass back to the tank is a great idea i hadn't thot of. Thanks SilverBell, i want a manual control so no fancy PID system.

I thought submersible pumps will be the handiest option. Found it difficult to get an alternative inline pump. would you know of any suppliers?

Whats the water going to be used for.
Are you recovering waste water or you recycling waste water.

More or less like a CNC machine .... coolant collects debris during cutting and you get rid of debris and use coolant again. In my case its water instead of coolant. And i would like the water to stay clear.
