Revision history [back]
I've used these in a number of places, but don't know what brand they were.
A number of manufacturers make water driven dosing pumps - (US Plastic Corp makes the DEMA MixRite dosing pump - the same pump is also sold as the Meditron - flow rates up to 0.7l/s). Dosmatic makes the Minidos (up to 0.75l/s). Obviously you could use several in parallel to get higher flow rates.
