Available in both 1-1/2" In/Out and 2" In/Out to fit all Dolphin pumps, priming pots should be used whenever an installation application may result in the pump intake not being flooded. Priming pots will ensure that the impellor volute area will remain flooded and the pump will always be primed. In addition, priming pots incorporate a basket strainer that will trap debris that might damage the impellor of your Dolphin pump. These priming pots are equipped with union fittings for easy servicing. Protect your investment!
