Gear Pump made in China Product Description This type of pump produces less noise than an internal eccentric design typically because of the lower speed it operates at but also due to the design of the teeth. As the helical parts are offset at an angle within the pump head a second set of helical gears are situated behind the main teeth to ensure the unit remains balanced. Gears are mounted above each other within the head with one being driven by the motor. They are timed to mesh with fluid flowing into the open cavities, rotated in between the teeth and casing and transferred to the outlet. What is an Internal (eccentric) Gear Pump? Operation within an internal design is similar to an External type in that the spaces between the teeth in the pump are filled with liquid. The liquid must be clean due to the gaps between the teeth being small. Liquid enters the meshed cogs, with part of idler sealing the inlet and driving the fluid towards the outlet.
