Be cautious when working with high-voltage and high-power motors, as they pose a significant risk if you are not well-versed in their operation. If you lack experience or knowledge, it is highly recommended that you refrain from attempting to work with these devices. To ensure optimal performance and prevent damage, utilize a double nut behind the impeller. I learned this lesson firsthand during my initial test run, when failure to use the double nut resulted in pump destruction. The pump features a bearing designated as KFL000 10mm, while the drive shaft is constructed from a 10mm threaded rod. Initially, the shaft began vibrating excessively during testing, prompting me to encase it within a steel tube for added stability. The motor powering the pump boasts an impressive 750 watts and rotates at 3000 rpm. I procured the bearing in question from AliExpress, where it was available for a mere €1.13. If you are seeking this specific bearing model, KFL000 10mm, you should be able to find it. The impeller used in my design is of the smallest size suitable for this motor and measures 10mm in height. This configuration offers several advantages: reduced clogging due to its vortex impeller design, coupled with ample space within the impeller's structure for fluid flow, resulting in approximately 80% of the water not making contact with the impeller. If you elect to use a motor with lower rpm specifications, larger impellers are available through my designs. However, it is crucial that you select an impeller size commensurate with your chosen motor, as failure to do so may lead to overheating issues. Prolonged use of this pump remains untested, as I only operated it for 2 hours during its initial testing phase. Therefore, the long-term effects of continuous operation are unknown at this time.
