Used LEYBOLD HERAEUS WAU-250 #9807 for sale

LEYBOLD HERAEUS WAU-250 is a highly efficient, oil sealed, rotary vane vacuum pump manufactured by LEYBOLD HERAEUS. This powerful oil sealed vacuum pump produces an ultimate pressure of 0.02 mbar and is versatile, durable, and exceptionally reliable. WAU-250 is designed to provide high pumping speeds across a wide range of pressures and vacuum levels. This is achieved by its oil-sealed rotary vane design, which utilizes a single stage diffusion pump as the core of the vacuum pump. The pump is also driven by a single motor which offers a great deal of flexibility and reliability when it comes to performance and maintenance. LEYBOLD HERAEUS WAU-250 is capable of a pumping speed of 64 cubic meters per hour, depending on the vacuum level. The pump is also equipped with an external gas ballast to improve pumping speeds on low and medium vacuum levels. With this gas ballast, molecules are able to pass into the pump, helping reduce the backflow of gas molecules and thus allowing for higher pumping speeds. In terms of reliability, WAU-250 is built with a durable construction that ensures longevity and optimal performance. The pump utilizes a robust oil-seal construction, which guards against leakage and ensures no air loss. The oil-seal and chamber construction is also designed to effectively trap vapors, preventing them from entering the gas ballast and thus increasing performance. The pump is also equipped with a built-in thermometer and high vacuum valve. The thermometer is designed to monitor temperatures in the vacuum chamber and alert you when the chamber is at risk of becoming too hot. The high-vacuum valve, on the other hand, works as a valve which breaks down larger molecules preventing them from entering the pump and damaging it. In conclusion, LEYBOLD HERAEUS WAU-250 is a reliable, powerful, and efficient oil sealed rotary vane vacuum pump that is able to offer a high pumping speed and a great degree of versatility and operation over a wide range of vacuums. It is a reliable and durable device that is well suited to both industrial and commercial applications.
