The RS Series Pitot Tube Pump, also known as a Roto-Jet pump, is a single-stage, low-flow, high-head pump with a unique working principle: it combines centrifugal action with pitot-tube stagnation-pressure recovery. Compared with other high-pressure pump types, it offers a notably compact footprint and superior operating stability and service life.
