Used VARIAN HS-20 #9259159 for sale

VARIAN HS-20 is a high-speed, high-vacuum, diaphragm pump used in many vacuum systems. It is a low-cost, high-quality pump that is used in a wide range of applications, including semiconductor processing, laboratory research, and other industrial operations. VARIAN HS 20 features a single-stage, air-driven, diaphragm design that allows for fast pumping speeds and high ultimate vacuum levels. Its single-stage diaphragm design means that lubricant, particle-bearing air, and other contaminates are excluded from the pump chamber, reducing wear over time. The pump also eliminates the need for a separate oil mist trap to prevent the entrance of foreign particles or liquids. HS-20 has a sealed construction that ensures quiet and vibration-free operation. HS 20 has a brass forged body, reversible PTFE/stainless steel diaphragms, and a bolted body for increased strength and durability. This design ensures that the pump will have a long life with minimal maintenance. The pump also has a removable-end flange that allows for easy maintenance and access. VARIAN HS-20 can easily handle a variety of operating conditions such as fluctuating temperatures, high or low inlet pressures, and high or low RPMs. Its compact size and low power draw make it ideal for many applications, including laboratory, medical, and industrial. VARIAN HS 20's oil-free operation and adjustable exhaust valve make it an ideal choice for vacuum applications. The adjustable exhaust valve allows for controlled operation, reducing contamination from the exhaust and improving system efficiency. It also allows for different operating pressures and flow rates to be adjusted easily. HS-20 is supplied with an electronic control unit for convenient operation and an adjustable oil mist trap for redirection of oil mist and particles away from the chamber. It also features the optional introduction of ultra-high vacuum (UHV) components that make achieving ultra-high vacuum conditions easier and more efficient. Overall, HS 20 is an economical, reliable, and efficient pump that is perfect for a range of industrial and laboratory applications. The pump is made with quality components that make it lightweight, durable, and low-maintenance. It is designed to provide many years of reliable operation with minimal maintenance.
