Used VARIAN SD 200 #293620872 for sale

VARIAN SD 200 is a double-stage diffusion pump designed for a variety of vacuum applications. It has a two-stage design, with a high-density, chemically inert, fluorocarbon vapor shield at the inlet of the pump and a separate drain baffle at its discharge. VARIAN SD-200 pump is capable of operating at a relatively high 10-6 Torr, while simultaneously providing superior low-to-medium-vacuum operation. SD 200 pump is constructed using durable, thermally conductive materials, such as aluminum and stainless steel, for its vapor shield, baffle, and motor housing. The motor housing also contains a special airflow circuit that increases overall cooling efficiency and yields greater performance. The motor is typically a direct-current (DC) motor, although alternating-current (AC) motors are also available. The pump has a nominal speed range of 100 to 2000 revolutions per minute (RPM). The maximum allowable inlet temperature is typically 295 Celsius (C). An optional baffle system can be fitted in the pump inlet, which helps to reduce condensation at higher pumped gas temperatures. The pump is shipped with an internal oil reservoir, which helps to conserve pump oil use and makes for easy maintenance. Additionally, SD-200 does not require the frequent filling of oil, thereby resulting in lower maintenance costs. The pump has a built-in displacement controller which helps maintain optimal oil level. VARIAN SD 200 features a large-diameter compressor, which enables increased gas throughput, as well as a long operating life. The pump house is designed to provide superior base pressure stability. It contains a low-noise muffler system that reduces noise levels to less than 70 dB(A). Overall, VARIAN SD-200 is an ideal choice for a wide variety of industrial and laboratory vacuum applications, including hardware cooling, electronics production, sputtering systems, distillation, and vacuum metallizing. The double-stage pump is designed to provide superior performance at an attractive price point.
