Oil-Free Screw Vacuum Pump Body Stainless Steel Casting

With the continuous demand for cleaner production environments in modern industries, oil-free vacuum technology has become essential in sectors such as semiconductors, pharmaceuticals, food processing, and new energy. Among these, the oil-free screw vacuum pump plays a critical role, and the quality of its core component—the pump body casting—directly determines the overall system performance. The Oil-Free Screw Vacuum Pump Body is a critical structural component manufactured using high-grade stainless steel and precision casting processes. It features excellent sealing performance, corrosion resistance, and mechanical stability.

1. High-Precision Chamber Design：The internal chamber is machined with high precision to ensure micron-level clearance control between screw rotors, enabling efficient vacuum performance.
2. Oil-Free Operation Structure：The pump body supports completely oil-free operation, eliminating contamination caused by traditional lubrication systems.
3. Excellent Thermal Stability：Optimized flow channel design and material properties allow stable operation under high-temperature conditions.
4. Superior Corrosion Resistance：Manufactured from stainless steel (e.g., 304 / 316), the pump body resists various chemical media corrosion.

1. Precision Investment Casting：Investment casting enables one-piece formation of complex structures with high dimensional accuracy and surface finish.
2. Stainless Steel Sand Casting：For larger pump bodies, sand casting improves production efficiency and reduces cost.
3. CNC Machining：Multi-axis CNC machining ensures critical dimensional and assembly accuracy.
4. Surface Treatment：Surface treatments such as polishing and sandblasting enhance durability and aesthetics.
