Used STOKES 412-11 #9298547 for sale

STOKES 412-11 is a mechanical sealless centrifugal vacuum pump and compressor designed to provide high efficiency and reliable performance. Constructed of cast iron and aluminum, the pump's chrome-plated metallic impeller, check valve, and cylinder liners are corrosion and erosion-resistant. 412-11 operates at a capacity of 11 cubic feet per minute (CFM) at a maximum pressure of 150 psig with an air-flow-over-impeller design that minimizes energy consumption. A double-suction impeller design ensures reduced axial stress on the pump and reduces radial forces that can result from pressure imbalances. The pump features a robust, single-stage, dry-coupled design. The pump body is supported on the frame by four rigidly mounted springs, which reduce vibration, extend pump life, and reduce friction between the moving parts. An external drive can be connected to the pump body for operation on a motor directly, while additional air can be supplied to the pump's air inlet ports to increase performance. STOKES 412-11 meets the most stringent safety requirements, including NEMA requirements, for use in research applications. All components, including the mechanical seal and bearings, are designed for high temperature and pressure capabilities to ensure exceptional product quality and performance reliability. The optimized mechanical design increases durability and performance while reducing operating costs. Additionally, the advanced impeller design provides the highest efficiency of suction pressure. The design of 412-11 is such that it can be easily installed and serviced in maintenance-free applications. The pump is also available with different flange options, including NPT connections, as well as different operating voltages. STOKES 412-11 is an ideal pump for vacuum processing and other general pumping applications. It is reliable, efficient, and provides an excellent return on investment. This pump is perfect for a wide variety of industrial, commercial, and research environments.
