The noise from external gear pumps has been significantly reduced by a new design which consists of two sets of gears, half the width of a standard gear, and offset about 1/2 pitch. The new pump makes use of a housing which is externally basically the same as a standard pump. This paper presents test stand and field measurements of the pump.
