TWO-STAGE PUMPS

Two-stage hi-low pumps are available in our 200 and 300 series. These pumps feature an internal unloading valve that diverts high-volume flow at minimum pressure when high-pressure flow is required. The pumps are designed to direct couple to gas engines or AC electric motors that turn up to 3800 RPM for 200 series, and 3500 rpm for 300 series models. The unloading feature assures that a small, efficient motor can be utilized effectively. MTE two-stage pumps are available in a number of different pump combinations, as well as shaft, flange and porting configurations.
