Very interesting. Im looking at getting a pump soon and this may be it.
ghart999...why would you say that the flow would drop by half at 3'? It has a maximum head of 14'. To me that means at 3', it would pump roughly 4.75gpm (Im sure its not linear, but its still more than 3gpm).
Head: Type:Stainless Steel
Suction/Discharger: ½” NPT
Note: impeller is made of Polysulfone plastic; O-ring is Silicon; thrust washer is Teflon
