Used PFEIFFER / BALZERS DUO 65 #9184721 for sale

PFEIFFER / BALZERS DUO 65 is a high performance, two-stage vacuum pump used mainly for industrial applications such as chemical vapor, vapors from process and reaction chambers, and other high-vacuum applications. BALZERS DUO 65 is a very versatile pump, capable of achieving ultimate pressures from 0.5 to 1.0 x 10-3 mbar and ultimate through-puts up to 315 l/s. Duplexing technnology is used to double the pumping speed, as two pumping stages are used in one package. The pump is designed to be energy efficient, using a 2.2 kW motor that requires only 156 W for dry running. This is a considerable saving in energy costs in itself, let alone the savings from the maintenance-free operation that is enabled by this pump. PFEIFFER DUO 65 is further designed with ease of maintenance in mind. The main components of the vacuum pump are modules which are embedded in the main unit, requiring less time for repair or replacement. The pump head also allows optimal servicing situations, and the modular construction allows it to be dismantled for maintenance in short periods of time. The pump is fitted with temperature and high speed detectors to ensure safe operation, as well as a removable purged gas connection to ensure that the atmosphere inside the pump is at all times inert. Furthermore, a replaceable filter is part and parcel of the pump's set-up, helping operators maintain a clean and efficient operation. DUO 65 offers excellent exhaust quality, with a very low level of oil aerosols. This is beneficial for processes that do not require large throughput but require a high level of purity and stability in the vacuum. Highly polished surfaces used on the pump head and on the inlet and outlet flanges allow the vacuum process to stay largely dirt-free. Safety comes built into PFEIFFER / BALZERS DUO 65, with devices to protect the pump from overload, and automatic restart mechanisms. A range of valves and other accessories are also available to make the best of the pump performance. In short, BALZERS DUO 65 is a reliable and efficient two-stage vacuum pump designed to meet the exacting requirements of industrial vacuum-processing applications. An ideal combination of low power consumption, maintenance-free operation, and excellent exhaust quality adds to its appeal.
