Used LEYBOLD HERAEUS E75 #9172728 for sale

LEYBOLD HERAEUS E75 is a rotary vane vacuum pump capable of reaching a low pressure limit of 25 mbar. It is a three-stage, oil-lubricated pump that is designed for industrial and laboratory applications. This pump operates by the use of two vanes located in a rotor chamber where the oil film separates them from the chamber walls. Upon rotation, the vanes cut the gas molecules into the spaces between them and the chamber walls, forming a partial vacuum. This partial vacuum is used in various applications such as: medical, home-seal packaging, vacuum metallurgy and refrigeration. The pump is configured in a dry-running design which means that the pumped gas streams are flashed into the atmosphere, ensuring optimum pumping performance and significantly reducing exhaust noise levels. This feature also ensures a trouble-free use, as the pump does not require any oil for its operation. E75 is equipped with an integrated safety valve which opens at the set point to protect the pump from impairment due to high pressure or extreme temperatures. LEYBOLD HERAEUS E75 is characterized by its efficient and reliable performance, which is due to its robust design and maintenance-friendly operation. For effective cooling, an oil-cooled external radiator is incorporated into the pump. The oil which flows through the radiator is cooled before entering into the pump and is then circulated around the rotor chamber, which further helps to reduce the temperature difference between the inlet and outlet streams. Moreover, E75 also enjoys an automatic electrical protection system that prevents the risk of a break in the power supply during operation. Moreover, the innovative, direct driven integrated motor ensures a smooth, power-efficient operation. It also features an integrated flow control valve that is able to automatically adjust the supply of oil to the rotor chamber, to compensate for changes in operating conditions. Overall, LEYBOLD HERAEUS E75 rotary vane vacuum pump is the perfect choice for reliable and thorough vacuuming of both small and large volumes of gas. Its advanced and highly efficient design provided a highly dependable performance with minimal maintenance cost.
