Used ULVAC U-20P #9105066 for sale

ULVAC U-20P is an ultra-high vacuum pump that is equipped with a rotational-seal mechanical booster for high pumping speed and volume. It is a stand alone, diaphragm-diffusion pump typically used for applications that require ultra-high vacuum in space-constrained systems. The compact size and low power demand make U-20P a popular choice for ultra-high vacuum subsystems where portability, power and size are of primary considerations. ULVAC U-20P has no oil seals and uses a rotational seal design for vacuum separation, providing superior leakage control and isolation. This leads to increased Process performance due to stable operating conditions, and prevents contamination of the samples in the chamber. The diffusion pump uses dual stage construction, consisting of a two-stage diaphragm section, followed by a two stage conical section. It is capable of providing pumping speeds up to 20 l/m, with an ultimate pressure down to 8x10-10 Torr. U-20P comes with a powerful and quiet operation with an inbuilt bearing to support the high-speed rotating parts. It also has a wear-resistant sleeve for extended durability, eliminating the need for annual maintenance. Furthermore, insulation is applied to reduce electrical noise and vibration. ULVAC U-20P features a modified turbo-molecular pump with a titanium rotor carousel and built-in bearing positioner. The bearing positioner eliminates carbon wear. Further, it has a quick evacuation speed, providing a fast pumping base pressure. It is a CF flange based pump and its compact design allows customers to design their equipment within a limited space. U-20P also has a heavy-duty cooling system with an inbuilt knife-edge O-ring to prevent particles from adhering to any part of the cooling fan. This ensures an efficient and reliable cooling system. Additionally, the fan comes with a safety switch which shuts down the pump when the temperature rises above a predetermined levels, thus providing protection from overheating. ULVAC U-20P from ULVAC is a reliable and efficient Ultra-High Vacuum (UHV) pump, providing excellent process performance in a compact size. Its high pumping speeds, low power consumption and vibration resistant construction make it ideal for applications needing UHV in space-constrained systems such as research and development, production, maintenance and testing.
