Gear pump

Gear pumps are used to pump fluids even under specific conditions of viscosity, pressure, or temperature. High precision is guaranteed even in their internal tolerances, which makes these machines particularly ideal for viscous, clean, and lubricant liquids.

What is a gear pump and how it works

Gear pumps resort to technologies that, thanks to the action of gear wheels, guarantee excellent suction qualities. While operating, these pumps ensure a constant flow rate even in case of pressure oscillations.

These devices are composed of two identical gear wheels perfectly in contact: the first one is activated by the pump engine and drags along the second one, which rotates consequently. This way, the liquid fills the space between the gear wheels and is driven and pressurized toward the outlet.

The gears are placed on a shaft equipped with two inner bushings that are entirely immersed in the fluid. All these components – mixed with the operating effectiveness of the gear pump – guarantee smooth and nearly silent performance.

The structure and materials used in the components of gear pumps are strictly connected to the type of liquid to pump. Finally, the functioning of the gear pump is normally due to an electric engine.

According to their use, Fluid-o-Tech designs gear pumps both in their standard version or for viscous liquids. They can be used in specific fields in which high precision at very low-pressure oscillations is required: for instance, in the food service – for which we manufacture devices with materials suitable for food contact – and in the medical field.
