Used PFEIFFER / BALZERS WKP 500A #9386888 for sale

PFEIFFER / BALZERS WKP 500A is a roll-style mechanical vacuum pump that is typically used as a roughing pump in semiconductor and thin film technology processes. It is specifically designed to deliver high-speed, energy efficient performance, while maintaining low operating costs. BALZERS WKP 500A offers high pumping speed from its' two rollers, which increase or decrease rotational speed to achieve a precise pumping speed to match the required pressure. The rollers are made from hardened steel, which provides a longer lasting shaft and helps to reduce wear and tear from operation. Additionally, they have been designed to operate at full capacity for over 30,000 hours of continuous use. PFEIFFER WKP 500A incorporates a diaphragm valve that offers superior operational performance typical of oil-sealed roughing pumps. This valve equipment opens at specific pressures and closes if the pressure exceeds a predefined value. The system is then slowed down for a coreless operation that is not disturbed by motor start-up or shut down. Moreover, the diaphragm valve offers oil-free operation. This ensures the efficiency of the vacuum unit and prevents air pollutants form entering the environment. WKP 500A is also equipped with a cooling-water cylindrical insert that provides efficient cooling for the entire vacuum machine. This helps extend the life of the pump and its' components, while preserving a reliable operational performance. The pump's main frame is composed of aluminum alloy as well as baked heat-treated zinc-plated steel which is very corrosion resistant and long lasting. Additionally, the motor makes use of a B5 flange, which offers stability and low noise levels. PFEIFFER / BALZERS WKP 500A also has a high level of flexibility due to its easy installation process. In conclusion, BALZERS WKP 500A is an energy-efficient, long lasting, and reliable roll-style vacuum pump that is designed to deliver high-speed performance at low operating costs. It is ideal for use in semiconductor and thin film technology processes, and its features ensure a long lasting and reliable operation.
