Gear pumps are unique devices that aid in the transfer of liquids from one point to another. They involve gears that rotate around. As these gears turn, they create pressure which moves the fluid through the pump. Liquid enters the pump through an inlet, and is pushed out through an outlet. Gear pumps are of several types, and each type has a unique working principle. Gear pumps have quite an impact within a multitude of businesses: chemicals, food and beverage.
The most common type of gear pump is the external gear pump. These pumps are simple in design, so they are easy to manufacture as well as repair when required. The external gear pump consists of two gears the small gear and the larger gear. The smaller gear is used to facilitate movement of the larger gear. As the gears rotate, they also trap the liquid between the teeth and push it from the pump’s entrance to its exit. A wide range of applications of external gear pumps in industries such as chemicals, food & beverages, automotive and more. They are suitable for low to medium pressure on liquids of non viscous substances.
Internal gear pumps differ slightly from external gear pumps. In an internal gear pump, the gear that drives is the outer gear (see Figure 1). The pair of gears mesh tightly, and as they rotate, they drive the liquid from the inlet to the outlet of the pump. Such pumps are useful in chemical processing industries, food industries, and hydraulic machinery. Internal gear pumps are capable of pumping viscous liquids and capable to operate with medium to high pressure, thus are used in many applications.
The gears in gerotor pumps have a specialized configuration. First of all, in gerotor pump, inner gear has less teeth than outer gear, leading to formation of spaces or gap between them. As the gears rotate, the liquid is forced through these clearances from the inlet to the outlet. Gerotor pumps are useful in applications where high pressure and high temperature is needed, such as critical applications like high-pressure hydraulic systems and oil & gas drilling, and unique applications in the airplane. They do well in situations where we need to be efficient.

Different types of gear pumps use different design, accordingly are useable for different type of work. External gear pumps perform best for tasks requiring low to medium pressure. Their straightforward design enables them to be easy to operate and maintain. Internal gear pumps can withstand higher flow rates and are more701503105391121N1 capable of withstanding higher pressure than external gear pumps. This make them tougher job-use durable. As a result, gerotor pumps are often used in demanding applications, as their high efficiency allows them to work with high pressure and temperature.

Gerotor pumps are distinctive due to their gear configuration. That allows the inner gear to rotate inside of the outer gear, creating spaces that liquid can pass through. The fluid travels through the gaps as the gears turn, enabling smooth functioning. Gerotor pumps are used when the flow is needed at the high rate of flow, high pressure application. This makes them also suitable for industries like oil and gas and aerospace where performance along with reliability matters.

Here are some key factors to consider when choosing the right gear pump for the job. Some of these are the viscosity of the liquid (how thick is the liquid), the flow rate (how much liquid do you need to move), the pressure required, and the temperature of the liquid. The external gear pumps are suitable for liquids of low viscosity implying thin fluids. They are also great for low to medium pressure applications and tend to be less expensive. Similar to gear pumps, an internal gear pump is suitable for the transfer of thicker liquids and can withstand moderate to high pressure which works well for the heavy jobs. Gerotor pumps thrive in high pressure, high temperature, clean or dirty fluid, and high viscosity services.
