Used EDWARDS iQDP40 / QMB250 #9291888 for sale

EDWARDS iQDP40 and QMB250 pumps are two powerful, reliable products providing reliable and efficient pumping of process gases and liquids. These pumps are constructed to provide superior performance, efficient operation, and low maintenance. The design of EDWARDS iQDP40 and QMB250 pumps feature a single-ended configuration with symmetricized and concentric intake and exhaust porting, allowing for optimal flow and cooling. The construction of the pumps utilizes custom made front and back cover plates finished in a solid aluminum block and precision machined on 5 axes, for superior accuracy in alignment. EDWARDS iQDP40 and QMB250 pumps are designed with a 4kW, brushless synchronous motor for superior performance and reliability. The pump has an operating speed range from 6,000 to 12,000 rpm with a maximum rotational speed of 18,000 rpm. The unique design of the motor results in a low vibration running optimised for certain applications with soft or harsh fluids. EDWARDS iQDP40 and QMB250 pumps utilize a four-stage pumping principle with a fully enclosed design that is ideal for transferring cryogenic as well as non-cryogenic fluids. The four-stage operation consists of an oil-free fan stage for low pumping speeds, combined with a high vacuum for evacuating packed lines, followed by a two-stage high pressure ranging from 0.1 to 8.3 bar (1-83kPa). The pumps also employ an exhaust pulse dampening system which allows a powerful, efficient pumping speed whilst keeping noise levels to a minimum. EDWARDS iQDP40 and QMB250 pumps are designed to deliver superior performance and precision. The pumps have a high tolerance for normal operational fluctuations and are built to last, offering a reduced need for maintenance and repair. The pump shaft is supported by a low wear bronze bearing allowing maximum pressure and flow with a minimum of drag force. The pumps are also equipped with a high performance oil-injection lubrication system ensuring continued, efficient performance over the life of the pumps. EDWARDS iQDP40 and QMB250 pumps also features a selectable, temperature dependent auto-reset function which ensures the pump is automatically shut off if the temperature limit exceeds a pre-set value. This helps to protect the pump from any possible damage that may be caused by the use of corrosive fluids or high temperatures. In conclusion, EDWARDS iQDP40 and QMB250 pumps are two powerful, reliable pumps constructed to provide superior performance and backed up by a low maintenance design. The robust design and reliable operation make them an ideal choice for many industrial applications.
