Product Description Product Description The impeller is mainly composed of blades, shaft core, and casing. The blade is the core part, with various shapes including forward, backward, and radial, which directly affect the working characteristics of the impeller. The shaft core provides rotational support to ensure stable rotation, while the casing protects and guides fluid flow. According to the form of the blades, impellers can be divided into three types: open, closed, and semi open. The open impeller structure is simple and suitable for handling fluids containing large particle impurities; The closed impeller forms a closed space, improving the accuracy and efficiency of fluid transportation; The semi open impeller combines the characteristics of both and is suitable for situations that require certain sealing and anti clogging capabilities. Detailed Photos The impeller refers to both the disc with moving blades, which is a component of the impulse turbine rotor, and the general term for the disc and the rotating blades installed on it.Product Parameters Unmarked dimensions refer to the 3D model.The cup shaft needs to be injection molded together with the impeller.All draft angles are 0.5 °, unless otherwise specified.The blade circumference is evenly distributed, with a draft angle of 0.15 °.The top pin print should be lower than the surface of the attachment.The sprue should not protrude from nearby surfaces.Flying edge and break deviation less than 0.1mm, residual gate less than0.3mm.
