5 mm Shaft Backward-Vane Pump Impeller
This is an open centrifugal impeller, 50 mm across and 16 mm tall. It has six backward-curved vanes 9 mm high on a 3 mm back shroud. The hub has a 5.2 mm bore for a 5 mm motor shaft and is locked with an M3 set screw that threads into a captive nut, dropped into a 5.7 mm slot from the top. Use it to rebuild a pond or fountain pump whose impeller has cracked, or to make your own small DIY water pump. Print it in PETG if it will sit in water.
