A-Series Direct Drive pumps are built for the highest head, high volume applications, to tackle the longest runs and tallest falls. A-Series pumps feature heavy-duty cast iron and stainless steel housing for years of dependable service. The continuous duty Direct Drive motors reduce maintenance to simply keeping the intake screen clean. A-Series pumps feature double silicone carbide mechanical seals and dual drive bearings that reduce friction and wear, prolonging motor life. The thermal overload protection shuts down the pump in low water conditions, to prevent serious damage due to overheating.
