Used VARIAN SD 300 #109970 for sale

VARIAN SD 300 is a pump that is designed to be used in a variety of applications, specifically those that require a great deal of precision and accuracy. It is capable of providing a vacuum level up to 10-4 torr and has a flow capacity of up to three liters per minute. The pump is constructed from a rugged alloy, making it highly durable and capable of withstanding extreme temperatures and pressures. The motor is sealed with magnetic bearing seals, which provide a leak-proof seal that allows the motor to run efficiently and effectively and keep the vacuum level at a consistent level. The pump operates using a lubricated dry piston and a dry helical screw compressor. The helical screw compressor is located in a chamber which separates the discharge and intake lines, allowing for improved performance and prevents water vapor from entering the chamber, contributing to a lower vacuum level. The dry piston is driven by the motor and provides improved pumping performance, along with controlled inlet and exhaust flow that can maintain the vacuum level at a designated setpoint. SD 300 can be customized with an array of options including an adjustable gas ballast and escapement valves, allowing for precise nitromethane control and improved reliability. The escapement valves, in particular, enable the pump to accurately control the volumetric flow, resulting in a stable vacuum level throughout the operating environment. VARIAN SD 300 is a powerful and reliable vacuum pump, ideal for a variety of applications such as vacuum drying, vacuum degassing and electroplating processes. The pump is designed for long-term performance, making it an ideal option for those who are looking for a reliable and efficient solution.
