Designed for use in gray water/filtered effluent service applications, the C1 Series cistern pump provides high performance and long life in less than ideal water conditions. The C1 Series pump is able to pass solids up to 1/8 in. without having a negative effect on the internal hydraulic components. The pump's unique bottom suction design allows for maximum fluid drawdown without compromising durability or overall life and it does not require the use of a flow induction sleeve. Intended specifically for use in a cistern or tank, C1 Series pumps are suitable for use in agricultural, residential and commercial installations.
