Centrifugal wind driven pump for raising water - has ascending tube supported by roller and sliding bearings

摘要

The centrifugal pump for deep water sources has an ascending tube (1) fitted with a check valve and having at the upper end a delivery tube (2) with two spring valves. An extension of the ascending tube has a filler chamber (3) with a filler union (4) and the ascending tube is supported vibration free above the water level by roller bearings (5) and below the water level by a sliding bearing (6). USE/ADVANTAGE - Centrifugal pump constructed of commercially available components having no mechanical friction losses and requiring a low energy input, windpower.
