Used PFEIFFER / BALZERS WKP 2000A #189858 for sale

PFEIFFER / BALZERS WKP 2000A is a turbomolecular pump designed for use in bakeable vacuum systems, particularly in the semiconductor industry. It is designed to provide reliable, high pumping speed for a variety of gases. The pump features a modular structure that is easy to assemble/disassemble and maintain. It is powered by a direct current (DC) motor and includes a cooling fan, an adjustable speed belt drive to regulate speed, and a pressure compensating mechanism to maintain constant pressure in the pump. The fan motor is protected with a thermal fuse and the high-speed motor is automatically protected against overloads. The pump has two rotors—an stationary and a moving rotor—that are driven by a 30,000rpm DC motor. The rotors rotate in pairs, one in a clockwise and the other in a counter clockwise motion, creating a vacuum inside the pump. This vacuum draws in the ambient gas from the environment and transports it towards the front of the pump, and continues this process until a preset pressure is reached. The moving rotor also expels a small fraction of the gas that is being pumped, in order to maintain the desired level of vacuum. The pump has an ISO-K flange attachment for vacuum hoses of different sizes, making it compatible with a variety of other equipment. Its compact design, measuring only 202x unless attached hoses, makes it suitable for use in tight, space-constrained environments. Additionally, BALZERS WKP 2000A includes a number of built-in sensors to monitor the pump's performance. These sensors are capable of measuring the pumped volume, pressure, and temperature. They also provide data on rotor speed, motor current, and power consumption, helping to ensure the optimal operation of the pump. Overall, PFEIFFER WKP 2000A is a high-performing, reliable turbomolecular pump that is ideal for use in space-constrained, bakeable vacuum systems. Its design allows for easy assembly, maintenance, and data monitoring. Its modular, ISO-K flange attachment, and 30,000rpm DC motor make it suitable for a variety of applications.
