Used ULVAC LR1800 #9053289 for sale

ULVAC LR1800 is a cryogenic pump that is used to transfer vaporized materials into high-vacuum systems. It is capable of achieving pressures down to 10-8 torr, with a pumping speed of 14 liters per second (l/s) for nitrogen and 0.58 l/s for hydrogen. This pump works by stripping gas molecules from the chamber via diffusion. First, a backing pressure is created from anaspirator valve in the pump. Then, the molecules enter the pump and collide against a cold trap, freezing them as a liquid. The locked molecules are then swept away by a rotating drum, leaving the vacuum chamber empty. LR1800 features a convenient oil-free pump mechanism in a compact package. The superior design improves system reliability and reduces maintenance requirements. The rotatable inlet flange increases installation flexibility. Additionally, the oil-free design allows operation at lower vibration levels and longer oil-free life. The pump can be connected to the controller remotely to manage the operational parameters. The dust filter, which is a part of the pump, prevents contamination from external sources. ULVAC LR1800 is also equipped with a cooling fin, providing excellent heat dissipation. With all these features, LR1800 ensures efficient operation and improved uptime. ULVAC LR1800 is a reliable and reliable cryogenic pump that is ideal for transferring material into high vacuum systems. It provides superior performance and low maintenance requirements, in a compact and efficient package.
