Magnetic coupled rotary vane vacuum pumps from Ulvac, Metheun, Mass, are designed to eliminate oil leaks and minimize shaft seal wear. From the company’s GHD series of products, the pumps perform at a power consumption of 100 W at maximum pressure, with a noise level of just 50 dB. Boasting a small footprint, the pumps measure 120 mm x 289 mm x 163 mm. They are also environmentally friendly and stay cool while being operated, with a stable temperature from 20°C to 30°C. Features include an integrated check valve located below an inlet port, which eliminates oil backflow; and magnet coupling, which prevents oil leakages from the shaft seal and consequently prolongs pump life. The pumps operate on a 100–120 V motor. For more information, visit Ulvac.
