Used EDWARDS QDP40 #9171301 for sale

EDWARDS QDP40 is a turbomolecular pump designed for a wide range of applications. This pump has a pumping speed of 6 L/s for hydrogen, and a pumping speed of 10 L/s for air. It also features an operable pressure range from 10-8 to 10-2 mBar. EDWARDS QDP 40 utilizes a two- stage, double-sided rotating turbine wheel to produce a non-contact pumping action. The pump has a patented oil-free vacuum system that removes outgassing components and leaves the process chamber free of particles. This pump contains high-energy magnets that produce a strong radial magnetic field and force the turbine to rotate at speeds of up to 138300 rpm. This fast rotation creates centrifugal forces that drive the gas molecules away from the rotor and into the spinning chamber, keeping the molecules totally separated from the rotor and away from the mechanical seals. This effect increases the pumping speed of QDP40, making it more efficient than other vacuum pump designs. QDP 40 has excellent speed and pressure performance, as well as high temperature range capability. This pump is designed for use up to temperatures of 250°C. The advanced motor features low power consumption, low noise level, and smooth operation. It is a self-contained unit that is easy to install and maintain. Its low capital and running costs make it cost-effective for a wide range of applications. EDWARDS QDP40 is engineered to deliver reliable performance under difficult operating conditions. Its robust design ensures superior protection against the occasional loss of electrical power. The pump is equipped with an overload protector circuit that prevents it from over spinning and drawing excessive power. Additionally, it features an overload reset function that allows the pump to restart automatically if it is shut off due to an electrical overload. Overall, EDWARDS QDP 40 is a reliable and efficient turbomolecular pump designed for the demanding requirements of various industrial and research applications. It is a cost-effective solution for high-vacuum pumping needs.
