This pump comes stock without any housing, allowing you to integrate any of your favorite pump tops and accessories. Consequently, the pump cannot be used as a standalone unit. Do not run the pump dry.The D6 and DDC range of pumps are designed to be self-lubricating, meaning the fluid that the pump is designed to move is also used to lubricate its internal parts. Therefore, you should not run the pumps without fluid for any reason. Running these pumps dry creates internal friction between the ceramic bearing and bearing housing, and that heat can quickly crack or melt the bearing housing.Running D6 pumps dry (without fluid) immediately voids the warranty. Replacements will not be provided under these conditions.It is easy for us to determine if your pump has been "run dry" or without fluid:Visual scratches along the inside of the housing. These are created when the bearing housing melts and the impeller spins off-center.The bearing housing has stress cracks or is melted, resulting from heat created when the pump is r
