Used VARIAN SD 40 #293642953 for sale

VARIAN SD 40 is a precision, lubricated, diaphragm-type vacuum pump capable of developing a deep vacuum and low pressures in an easy, reliable manner. This vacuum pump is typically used in laboratories and industrial applications, such as vacuum filtration, vacuum distillation, and freeze drying. The pumps design has a low profile, enabling a low-heat dissipation and minimal space required around the pump. This also helps keep the noise level and installation cost to a minimum. SD 40 features an oil-less motor construction which allows for smoother, vibration-free operation and prevents the need for oil over the long life of the pump. In addition, this vacuum pump contains the finest quality parts for trouble-free operation. The operation of VARIAN SD 40 vacuum pump is achieved by means of a two-stage ball bearing motor, which is made of high strength, corrosion resistant steel for durability. Additionally, the motor is oil-neutralized and utilizes a diaphragm vacuum design with Teflon seals. This design allows for low energy consumption and a low cost of ownership. The body of SD 40 is made of durable aluminum alloy with a chemical resistant finish. It has an oil drain plug, front and backports, and a gas ballast valve which can be adjusted without the need for additional tools. The body is well-ventilated, which allows it to operate at low temperatures and in high-vacuum situations without any risk of overheating. Additionally, VARIAN SD 40 incorporates a manual isolation valve that helps ensure a smooth start-up and minimizes disruptions to the vacuum level. As the pump operates, it creates a vacuum in the body, which is sealed to keep any moisture or air from entering the vacuum chamber. This helps maintain a constant vacuum pressure in the chamber. SD 40 is an efficient and reliable vacuum pump when used correctly. It features an oil-less construction for a longer product lifetime, operates at low temperatures, and creates a deep vacuum to achieve low pressure levels. It has a durable, aluminum alloy body, manual isolation valve, and adjustable gas ballast valve.
