• Liquid enters the pump via the suction line (Blue) of the specially designed, interchangeable
distribution manifold, passes the mechanical seal (the mechanical seal is only under suction
pressure), and enters the rotor cover where it is accelerated to a speed identical to the rotor speed
creating a liquid ring.

• The liquid ring travels at the same peripheral speed as the rotor and this moving fluid has a velocity
head.

• The stationary, wing-shaped Pitot tube is placed inside the rotor and has a circular opening located close to the inside of the rotor.

• This Pitot tube has a double function.
1) The liquid enters the Pitot tube openings at the periphery of the
rotating rotor. This is where the velocity is the greatest.
2) As the liquid enters the Pitot tube (Red) much of its kinetic
energy is converted into pressure energy by the internal shape
of the Pitot tube. Using this operating principle, relatively high
pressures can be obtained in a single stage process.

• The pump generates a pulsation free flow and has a stable NPSHr curve.
