Used ULVAC RBH-22BL #293627432 for sale

ULVAC RBH-22BL is a diaphragm-type vacuum pump designed to provide ultra-high vacuum conditions with minimal emission. This pump is one of the most reliable pumps with a wide operating range, designed specifically for research applications. It features a dual loop double-diaphragm structure that incorporates a pair of durable stainless steel inner bellows. This structure allows for precise control of the pumping speed without compromising air tightness or safety. RBH-22BL uses environmentally friendly lubricants, providing low noise levels and long operational life. The powerful yet lightweight pump features an integrated dry oil mist remover, which actively removes any contaminants from the pumped air stream, allowing for a clean and reliable operating environment. An adjustable pressure control valve is also included as standard on ULVAC RBH-22BL, allowing for precise regulation of the desired operating pressure. This feature ensures that the pump operates efficiently and maintains a stable pressure level throughout its operating range. RBH-22BL has a convenient starting voltage of only 1~24 VDC and is capable of vacuum pressures down to 1 x 10-6 Pa with an ultimate pressure of 2 x10-9 Pa. This is suitable for short-term operating conditions and/or operating duration periods up to 1,200 hours. Additionally, robust inlet and outlet valves enable quick and easy installation. The product's control system has been designed with safety in mind, featuring a built-in safety system that prevents overpressure and overheating of the air and oil. In addition, the independent safety valves on the product have been rigorously tested to pass strict criteria and provide reliable protection and optimal performance. The product also has inbuilt sensors that monitor the oil temperature, and these sensors are capable of detecting any failure of the cooling system. ULVAC RBH-22BL has an entering port diameter of DN 16, and an exhaust port diameter of DN 63. It also has an automatic air vent valve, ring seals and a durable cold-rolled steel shell made from an electroplated steel and polypropylene blend. The product features a reinforced drain port and an adjustable valve seat, making it easy to use and maintain. Additionally, the unit is available in two different models with different airflow capacities, and it comes with a range of accessories such as flexible connectors, silicone oil, filter tests and a filter holder. ULVAC RBH series of pumps uphold the highest standards of quality in the industry and are backed by an extensive warranty for optimal performance and longevity. With its reliable performance, superior design and easy maintenance, RBH-22BL is a must-have for any research laboratory looking to provide ultralow vacuum conditions.
