Solar Water Pump Motor Housing

Designed to meet sealing and connection requirements for fluid control valve bodies, pump covers, or mechanical transmission housings, this component features a circular disc structure. It is configured with four evenly distributed large-diameter through-holes at the center and a flat annular mounting flange extending from the outer edge. This layout is commonly used in hydraulic systems, gas appliances, or industrial pipelines as an end cap for medium diversion chambers or a support interface for bearing seats. The flange face aligns with the base body to achieve axial positioning, while the internal large holes accommodate shaft systems, valve cores, or form fluid channels.

The core of machining such disc-shaped parts lies in strictly controlling the center-to-center distance tolerance of the four large holes and their coaxiality relative to the outer circle, ensuring no interference with internal moving parts during assembly. Additionally, the flatness of the flange face must be guaranteed to prevent seal failure or uneven stress distribution caused by warping. For the recessed stepped cavity structure shown in the image, special attention is paid to controlling step depth and sidewall perpendicularity. Cut edges undergo deburring and chamfering to eliminate sharp edges, preventing damage to sealing rings or injury to operators.

Leveraging our manufacturing experience in hardware and electronic components, we utilize bench drilling machines combined with CNC milling processes to achieve precise hole patterns and cavity forming, optimizing surface finish through vibratory tumbling. Key dimensions are rigorously inspected using dial calipers and height gauges to ensure batch consistency. When purchasing, please provide detailed drawings specifying material grades (e.g., 304/316 stainless steel, aluminum alloy, or carbon steel), surface treatment standards, and key mating tolerances to facilitate the evaluation of specific machining solutions and lead times.
