QP204H Centrifugal Pump is designed to handle all types of clear water applications It is ideal for residential use such as dewatering basements and swimming pools Both the suction and discharge ports on the QP 402H pump use a 4 inch diameter opening which allows the pump to pump at a rate of approximately 425 gallons minute gpm or 1 615 liters minute pm Centrifugal or self priming pumps are designed to purge air from the suction line and create a partial vacuum in the pump body The reduced atmospheric pressure inside the pump allows water to flow through the suction line and into the pump body The centrifugal force created by the rotating impeller pressurizes the water and expels it from the pump Power Plant This centrifugal pump is powered by either a Honda GX240K1 8 0 H P ora Honda GX240U1 7 1 H P air cooled 4 stroke single cylinder gasoline engine that incorporates a low Oil Alert Feature Oil Alert Feature In the event of low oil or no oil the HONDA GX 240 engine has a built in oil alarm engine shut down feature In the event the oil level is low the engine will automatically shut down Standard Centrifugal Pump Standard centrifugal pumps provide an economical choice for general purpose dewatering These types of pumps should only be used in clear water applications agricultural industrial residential as they have a limited solid handling capability of only 10 by volume Suction Lift This pump is intended
