Used LEYBOLD HERAEUS D90AC #9217751 for sale

LEYBOLD HERAEUS D90AC is a diaphragm dry roughing pump designed for applications requiring very low ultimate total pressure. This innovative pump is capable of providing a reliable, efficient performance within a wide range of operating conditions. With its optimal oil-free design, it offers similar ultimate pressures to that of larger and more expensive oil sealed pumps. D90AC is a double-ended dry diaphragm pump with a lightweight aluminum-alloy design, incorporating one or two stages. Its exterior is constructed from anodized aluminum with stainless steel components, making it highly durable and providing protection from corrosion. This construction allows for a smaller and more compact design, making it ideal for use in challenging environments. LEYBOLD HERAEUS D90AC is driven by an external direct-current (DC) motor, providing a reliable flow rate of up to 20 m3/h and a maximum pumping speed of 1,000 mbar. Its advanced brush-less DC motor is particularly energy-efficient and delivers a low noise level without compromising any of its performance. The motor is controlled using a dedicated controller, which allows easy setting and monitoring of the operating parameters. D90AC is impermeable to moisture, ensuring an extremely low ultimate vacuum level. It also provideds an excellent air-condensation capacity, preventing any contamination from the exhaust air. An integrated microprocessor monitors and controls the exact level of operation, thoroughly checking all the parameters such as temperature, oil humidity, and current. The powerful dry diaphragm pump has a noise level of no more than 67 dB (A) and is supplied with its own condensate separator. This separator has a structured diaphragm that is resistant to the formation of moisture channels and which prevents recontamination. LEYBOLD HERAEUS D90AC can be used for a variety of industrial applications, in particular those requiring a precise control of vacuum levels. It is suitable for a wide range of vacuum processes, from the filtration of liquids, to the treatment of gas samples. Other applications include food processing, chemical industry, industrial painting, film production, wastewater treatment, and defoaming. Overall, D90AC is an efficient, lightweight, robust, and cost-effective roughing pump that offers reliable performance for applications which require extreme levels of ultimate total pressure. Its advanced technology and energy-saving features ensure a high level of control and consistent performance, at a competitive price.
