: 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

A (shesternnyi nasos) is a type of positive displacement (PD) pump that moves fluid by repeatedly enclosing a fixed volume within interlocking gears. These pumps are widely valued for their simplicity, reliability, and ability to handle high-pressure and high-viscosity applications. Core Working Principle

: As the gears disengage at the inlet, they create an expanding volume. This generates a partial vacuum, drawing fluid into the pump.

: 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.

The basic mechanism relies on two gears rotating inside a closely fitted casing.
