Dear Lloyd and fellow list members, Further to the dicussion on pumps for circulating fluids in compost teas and flow forms there is another type of pump which has recently been developed in Australia. At the last AGM of the BDFGAA Mr Rob White released the prototye of a peristaltic pump which pumps the water in a pulse form. I saw a demonstration of it and I am not quite sure of the volume pumped, somewhere in the vicinity of 600 litres / minute off a 1/4 hp motor. The pump was developed by Rob White who is the BDFGAA advisor on matters of stirring and pumps.
I will keep you all informed when I hear some more about where Rob is up to with the pump. It is a very ingenious solution to the problem of what sort of pump to use with BD preps.
