Used ULVAC HR90 #9409383 for sale

ULVAC HR90 is a rotary vane vacuum pump manufactured by ULVAC (Ultra Low Vacuum Advancement Corporation). This type of pump uses a rotating set of vanes to produce a partial vacuum, while controlling the inlet flow of air and exhaust it. HR90 employs an oil-free, air-cooled and maintenance free design to ensure reliable operation and extended lifespans. Combining superior displacement with a design that optimizes performance and lowers cost, ULVAC HR90 is a reliable solution for applications that require controlled vacuum pressure. HR90's electric motor powers a set of seven stainless steel vanes, which are held in slots within the rotor. As the speed of the motor increases, the pressure of the evacuated air column drops, creating a partial vacuum. The vanes create a sealed chamber as they pass through the rotor, allowing the air to be evacuated and then released into the exhaust port. The aggressive design of ULVAC HR90 also introduces pressurized air to further strengthen the vacuum created by the vanes. A key design feature of the pump is the two-stage setting, which increases displacement and performance. Pressure sensors are incorporated to monitor the vacuum pressure and ensure it is maintained and reliable. Additionally, an integrated oil mist eliminator filters particles before the air is exhausted, while the intake side features a built-in air filter. This configuration allows operators to easily monitor the operation of the pump. HR90 is highly efficient and reliable with its operation. Its low noise level of 68 dB ensures the pump can easily blend into the background of a lab environment while reducing disruption. A wide range of accessories and features, from ball-bearing slide bases to adjustable pressure switch limits, make ULVAC HR90 an ideal solution for a variety of industries. Its robust construction, excellent performance, and dependability allows it to meet the demands of numerous critical and challenging applications.
