Robjack, As stated above the Barske (also written as Barski)impeller is one of the two keys to low flow high head pump design The other important ingredient is a concentric casing (rather than eccentric with a cutwater) This allows liquid to stay in the casing for more than one revolution around the casing, without the associated recirculation difficulties of cutwater volute designs It
