CNC Aluminum Alloy 40/60 80/100mm Propeller for Pulp Pump Jet Propulsion

CNC aluminum alloy water jet propulsion pump impeller:
1. For the high-efficiency impeller specially designed for marine water jet propeller and ducted propeller, the 4-blade large angle of attack design is adopted, and the pump injection and ducting are used to achieve high open water efficiency and anti-cavitation performance. The theoretical thrust of the impeller is increased by 72% compared with the 2-blade impeller.
2. This impeller is designed with CNC large chord length, providing a wide range of high efficiency in the pump spray.
3. This impeller is made of high-strength aluminum alloy and is processed by a multi-axis CNC machining center at one time without polishing. In order to ensure the dynamic balance of the blade, there are traces of cutting in the appearance, which is a normal phenomenon and does not affect the use. If you pursue a smooth surface, perfectionists should not buy it.
