How It Works

 

 

 

When the gear engagement is released at the inlet, the liquid is filled in the groove of the rotation gear.

If the space created by gear casing and plate is filled with the liquid, it moves toward the discharge along the inner casing circumferential surface.

Liquid flows out from the discharge port by the gear engagement.

Thus, gear pump is a fixed displacement pump of the constant flow rate.

Besides a simple structure with a low pulsation, it has a feature that can be manufactured to a very precise.
