V-Series wastewater pumps from Webtrol Pumps have a recessed, cast iron impeller that prevents clogging, providing more life from the pump. The motors are air-filled and offer continuous-duty ratings. To protect the motor from water, the pumps come with potted epoxy cord seals as well as double silicon-carbide mechanical seals, providing defense against water intrusion. All single-phase motors come with overload protection. Constructed from stainless steel and cast iron, these pumps are available from 1/2 up to 2 hp, 115- and 230-volt, single- and three-phase. 800/769-7867; www.webtrol.com.
