Hi
Thanks for the reply. This morning I found the "Base and Tub Assembly" step file from which I took some measurements. The Phoenix pump from Scott Machinery (which should be a good brand) comes in either 105 or 150mm foot length. The Tormach tank height is 214mm so the 150mm pump will have some clearance. I calculate the usable tank volume after allowing for the pump height to be about 19.5 L, so the Phoenix pump will cycle the usable tank volume in about 50 seconds at 25 L/m so I don't think the capacity of the pump will be a limiting factor at this point.
