Used LEYBOLD HERAEUS D65B #9246772 for sale

LEYBOLD HERAEUS D65B is a robust, single-stage, dry-running rotary pump specifically designed for pumping liquids with low to moderate vapor pressures. The pump utilizes an oil-lubricated, vaned rotary vane, which rotates in an enclosure, or clamp ring, so that a near-perfect vacuum seal is created between the pump's inner and outer walls. The rotors are mounted on a plate-like shaft, held by two semi-circular housings, which are connected with an external wall. The vanes are set into the shaft by means of springs which cause a predetermined voltage when the rotors turn. The rotors on LEYBOLD HERAEUS D65 B are driven by either a belt or direct means, allowing for greatly increased pumping speeds. The motor driving the rotors is rated in watts, allowing for consistent pumping speed. Motors with three-phase AC supply are usually recommended to achieve full efficiency. The motor and the pump housing are air-cooled by a fan, and the fan speed is regulated by temperature sensors. The vacuum created by D65B is adjustable between 0 mbar and 1 mbar, thus it can create a wide range of vacuum pressures depending on the application. D65 B is suited for a variety of applications such as low-pressure cooling, degassing of liquids, filtration and distillation of liquids, low-pressure gas transfer, and more. Additionally, it is recommended for applications requiring aspiration and evacuation of gases and vapors. Due to its robust design, LEYBOLD HERAEUS D65B can operate in a wide range of temperatures from -10 degrees celsius to up to +50 degrees celsius with minimal losses in performance. In terms of maintenance, LEYBOLD HERAEUS D65 B pump is relatively straightforward with minimal parts that require frequent cleaning and lubrication. The most important maintenance step is oil renewal. The pump should be serviced every 600 hours. When servicing D65B, some components can be removed easily without special tools. Moreover, the vanes, rotor, and the clamp ring are designed to perform under high vacuum levels. Operating D65 B is a straightforward process, as the pump requires minimal setup and simple controls. With the use of a switch, the user can engage the pump at different speeds, which allows for a controlled and steady vacuum operation. Additionally, LEYBOLD HERAEUS D65B is equipped with an hour meter, which allows the user to monitor and determine the running time of the pump. In conclusion, LEYBOLD HERAEUS D65 B is a reliable, robust, and versatile single-stage dry-running rotary pump specifically designed to provide a wide range of vacuum levels. Its robust design allows for maximum reliability and service life while being convenient and cost-effective to maintain.
