About Us

Thompson sound-attenuated pumps with the Silent Knight® noise-reducing canopy are designed for operation at low noise levels. Silent Knight® units are perfect for projects near hospitals, schools and residential areas, or for emergency nighttime pumping. With sound levels of 70 decibels and below, Thompson pumps are quieter than competitive pumps on the market and cost less to operate. Silent Knight® pumps are tested under the most demanding methods to ensure low-noise job site performance.
