Pump Valve Flanges and Metal Stamping Parts

We provide complete sets of hardware components, including triangular irregular flanges, circular end caps, and mounting brackets, tailored for the assembly needs of canned motor pumps, micro-motors, and fluid control equipment. These structures are primarily used for sealing and fixing pipeline interfaces or for axial positioning of rotor components. Strict coaxiality between the center hole and peripheral features is maintained to ensure dynamic balance during operation and reliable sealing at connection points.

The manufacturing process focuses on dimensional stability of irregular contours and flatness control of mating surfaces. For the brass triangular flange, slow-feed wire EDM is employed to machine precision inner holes and outer edge steps, combined with precision machining to ensure accurate thread hole positioning. For other discs and brackets made of stainless steel or carbon steel, stamping and drawing processes followed by finishing operations ensure flat, burr-free end faces, effectively preventing leakage or vibration caused by uneven assembly gaps.

Supported by IATF 16949 and ISO 9001 quality management systems, our production services cover the entire workflow from material selection and mold development to final product delivery. Equipped with Sodick slow-feed wire EDM machines, precision surface grinders, and multiple high-speed punch presses, we flexibly handle non-standard customization requirements for high-mix, low-volume orders. Quotations and lead times are evaluated based on specific material grades (e.g., brass, Stainless Steel 304/316), surface treatment requirements (e.g., electroplating, passivation, or anodizing), and drawing tolerance levels.
