I am looking to replace a worn out bronze pelton wheel that is 9" dia
with a 1 1/4" shaft, head @ nozzle of 200 feet (86.6PSIG) nozzle dia
5/8", flow rate of 90 ImpGPM, with a speed under load of 1680RPM that
was purchased from Little Spokane Hydroelectric. If you sell or know of
a company that sells pelton wheels of that size which could replace the
one that is wearing out please let me know. Thank you for your help!
Looking forward to your reply.
