: The fluid becomes trapped in the spaces between the gear teeth and the pump casing. It is then carried around the perimeter of the gears as they rotate.
: As the gears disengage at the inlet, they create an expanding volume. This generates a partial vacuum, drawing fluid into the pump. shema shesterennogo nasosu
: When the gears mesh back together at the outlet side, the volume decreases, forcing the trapped fluid out through the discharge port under pressure. Main Types Construction and Working of Gear Pump.pptx - Slideshare : The fluid becomes trapped in the spaces
