Used EDWARDS QDP80 #9291876 for sale

EDWARDS QDP80 is a rotary vane vacuum pump designed and manufactured by EDWARDS Vacuum. It is an oil sealed mechanical pump that functions through a two-stage design including a primary and secondary stage which are connected through the internal rotor assembly. The two stages work together to achieve high pumping speeds, which makes EDWARDS QDP-80 a reliable and efficient high performance pump. The primary stage of QDP 80 is responsible for the majority of the pumping speed, and this is achieved through the use of two rotors and two mechanical slots. The rotors are mounted in bearings in the base of the pump head, and the slots provide a path for the air to be drawn into the pump from the atmosphere. The air is then drawn into the rotor chamber, where it is compressed and pushed up the vanes of the rotor. As the vanes move around the rotor chamber, the air is forced into the secondary stage of the pump, where it is compressed further and put under pressure. This pressure is then used to create a vacuum in the secondary stage, allowing the pump to draw the surrounding air into itself. Compared to single-stage pumps, the two-stage design of QDP80 allows for a much greater level of efficiency. It is able to reach a maximum pumping speed of 55 cubic meters per hour, and a maximum differential pressure of 1.3 mbar. The high efficiency of the pump also ensures minimal energy consumption which reduces operating costs. Additionally, QDP-80 is designed to operate reliably even in difficult conditions thanks to a number of safety measures such as an anti-suckback valve, a gas ballast valve, and an over-temperature protection system. EDWARDS QDP 80 is an oil lubricated pump, meaning that it requires regular lubrication to ensure the smooth running of its parts. This pump is also designed to be easily serviced, allowing users to easily replace worn-out parts and maintain its performance. As well as this, EDWARDS QDP80 pump is surprisingly quiet in operation, with a sound pressure level of just 60 dB(A). This makes EDWARDS QDP-80 a reliable and efficient pump for industrial or laboratory applications.
