Used Arneson Pool Sweep vertical booster pump stand (volute) part #37.Although booster pumps are still available, the custom volute is no longer made and intact used ones are very hard to find. This one was taken out of service when the booster pump failed. It developed a very small leak around the lower fitting 2 years ago that was repaired with epoxy (see photo) and has held firm since then. Included with the volute are the 3 legs #39, 4 bolts to secure the pump to the stand, and a used impeller #36 that's still in good condition and would sell new for 38.00-43.00. These booster pumps can also be used to drive Polaris and other pressure side pool cleaners.
