Dear Xavi, Pumps as turbines are fine on clean water and if the flow rate is known and constant. I would however suggest extreme caution when using them on projects where the site data is not good (most rural electrification and microhydro projects!) as they are very inflexible and usually very difficult to clean. The argument that you can screen the water is not valid in my experience because 'things' and 'creatures' always manage to get in somehow and if you cannot clean it out 'in the dark' in less than five minutes, I think you will have a problem.

I have read a little in using "inverted motors as a generator" and "pumps as a turbine". Could anyone tell me which are the advantages and the inconvenients for these two groups? I think that is not the price the only reason to replace them, isn't it? Thanks a lot. Best regards, Xavi __________________________________________________ Correo Yahoo!
