A pressurized motive fluid leaves a nozzle at high velocity and creates a vacuum in the mixing chamber; that vacuum draws in the product, and the two fluids, now mixed, recover pressure in the diffuser and leave through the discharge. It is used where a mechanical pump is difficult to install and, because it has no moving parts, it reduces noise and vibration.<\/p><p class=\"wp-block-paragraph\">The range has two models.
