Used EDWARDS QDP40 #9387148 for sale

EDWARDS QDP40 is a rotary vane oil-sealed high-vacuum pump. It offers the combination of high pumping speeds with ultimate vacuum pressure in the range of 5 x 10-2 mbar. The main features of this pump are its high efficiency, excellent performance and reliability. EDWARDS QDP 40 is a direct-drive pump powered with electric motor, and equipped with an air cooling fan. This ensures long service life and excellent performance even in hard environment. It is driven by a 3-phase AC motors which allows it to deliver high performance. The speed range is between 850 to 1400 rotations per minute. The pump operates without lubrication thanks to its oil-sealed design which eliminates oil vapor contamination. The oil-sealing system consists of both dynamic rings and a vapour-tight seal. The combined operation of these two parts durably maintains the high-quality vacuum without any oil vapor. The oil-sealing system does not require any maintenance while operating. QDP40 has a high gas-free pumping rate, capable of evacuate up to 90 m3 per hour with the ultimate pressure in the range of 5 x 10-2 mbar. Its vacuum chamber is equipped with multi-ply bearings which ensures smooth and low-vibration operation. This reduces energy consumption, and provides firm support to the pump for continuous operation. The pump is also equipped with an inlet filter to protect the vacuum chamber from dust and other contaminants. The built-in filter also minimizes the maintenance effort. In order to monitor the pressure and performance parameters, the pump is integrated with a vacuum gauge which displays the readouts such as a trend analysis, comparative analysis and predictive analysis. In summary, QDP 40 is an excellent rotary vane oil-sealed high-vacuum pump that provides reliable and cost-effective performance. It is capable of delivering high pumping speeds and long service life. Its oil-sealing system keeps oil contaminants at bay and its inlet filter provides extra measure to protect the vacuum chamber from dust and other contaminants.
