The 1/3 hp V-Series sump/effluent pump with automatic operation from Webtrol Pumps has a recessed vortex impeller, reducing the load on the bearing and helping prevent clogging, extending the life of the pump. The motor is air filled and offers a continuous-duty rating. To protect the motor from water, it comes standard with a potted epoxy cord seal as well as a carbon-ceramic mechanical seal. Constructed from stainless steel, cast iron and glass-filled polymers, it can be used for residential or light commercial applications. 800/769-7867;
