Used EDWARDS QDP40 #9291208 for sale

EDWARDS QDP40 pump is a robust, reliable and cost-effective device designed for use in HVAC systems. It's a non-positive displacement Rotary screw vacuum pump that offers excellent performance with a pumping speed up to 4 kW, making it suitable for a broad range of applications. The unique design of EDWARDS QDP 40 means it is able to pump air and other gases with ease, while being extremely resistant to wear and tear due to its robustness. The rigid construction also makes the pump highly reliable and serviceable. QDP40 is also energy efficient, as it uses small amounts of electric power even on high-usage applications. This efficiency allows it to have a low energy expenditure. The simple construction allows the pump to run with a range of shaft speeds, meaning it is suitable for a range of applications requiring a wide range of pressures. This makes it well suited to use in areas such as laboratories and medical settings, as well as for industrial applications. QDP 40 is constructed with a single rotating cylinder and two non-contacting helical screws and seals. The shape and size of the cylinder ensures optimal compression and expansion of air and gases, while the seals stop compressor oil entering the chamber. This prevents contamination of the atmosphere. It operates by building up pressure when the screws turn, and then pumps this at a pre-determined volume into the discharge pipe or hose. This pressure can be controlled according to customer needs, allowing it to be used in different applications. Furthermore, EDWARDS QDP40 has a high final pressure, with a maximum operating pressure of 4.5 bar, meaning it can handle air at a higher pressure than most other pumps can. This helps to make the pump suitable for a wide range of applications, such as powering pneumatic tools and machines. In summary, EDWARDS QDP 40 is a reliable, energy-efficient and cost-effective vacuum pump, constructed with a robust single-cylinder design. This makes it suitable for a range of applications and operating conditions, while the highly compressible nature of the pump ensures excellent performance, whatever the pressure.
