What is a gear pump?

Gear pumps move fluid smoothly with cogs or gears, drawing in liquid from the suction side and displacing it out the discharge side.

Gear pumps are a type of positive displacement pump that move a fluid with cogs or gears using a cyclic pumping action. 

They deliver a smooth flow in proportion to the rotational speed of the gears. Gear pumps are widely used to pump high viscosity fluids, such as molasses. Their fixed displacement design means they pump a constant amount of fluid for each revolution.

Gear pumps have a suction (or intake) side and a discharge side. As the gears rotate they draw in the liquid on the suction side of the pump. The rotating gears then transfer the liquid to the discharge side of the pump, where it is displaced by the engagement (meshing) of the gears with one another.  

A gear pump does not have any valves to cause friction loss, hence it is ideal for handling thick fluids such as molasses.

We carry two ranges of gear pumps for molasses handling: the BGC Series and the Rotoflo series. Both the BGC and Rotoflo gear pumps come in a range of sizes and suit a variety of applications. They can be fixed or mobile, and depending on the selected gear pump they can be adapted to be driven by electric motor, petrol engine, hydraulic motor or PTO.
