Key Features and Benefits of Internal Gear Pumps

Internal gear pumps use two gears, one larger and the other smaller, to displace fluids via a suction and discharge cycle, especially viscous fluids such as oils, chemicals, and food and beverages. These pumps are popular among industries because of their efficiency, reliability, and ability to handle a wide range of fluids.

Read on to learn about internal gear pumps' features, advantages, and significance in industrial applications. First, let's discuss their features.

Positive displacement design – Internal gear pumps are designed to displace a fixed amount of fluid with each revolution. As a result, they are an excellent choice for industries that require steady, consistent fluid transfer, such as pharmaceuticals and chemical processing.

Customised body - Depending on the application and the kind of fluid that needs to be displaced, an internal gear pump can be jacketed or heated (electrically) so that the fluid doesn't solidify during displacement.

 Versatile body material – The body of internal gear pumps can be made of metals such as cast iron, stainless steel, ductile iron and steel. This means customers can choose a pump based on the adaptability of the metal with their application or fluid. Since all these materials are robust, the pumps can withstand harsh operating conditions, including high temperatures and corrosive fluids.

Benefits of internal gear pumps

They are self-primed - One of the best features of internal gear pumps is the fact they do not need to be primed. Even during dry startup conditions, internal gear pumps can continue performing while removing air from the suction line, enabling a quick and reliable operation.

They can handle various kinds of liquids - Internal gear pumps are capable of handling fluids such as oils, syrups, adhesives, and molten wax. Their controlled operation ensures they can work with aggressive liquids without wear and tear.

They are compact – Internal gear pumps are compact in design, making them suitable for industries where equipment often needs to fit into tight spaces. The compact design also ensures these pumps  can be easily transported to remote locations.

They can be operated in two ways – Internal gear pumps can be operated both in forward and reverse directions, making them ideal for applications where bidirectional flow is required, such as fuel transfer systems and hydraulic circuits.

They offer precise flow control – Since internal gear pumps are positive displacement pumps that work in a way where two movements follow each other in a repetitive, controlled manner with accurate metering, the result is precise control over the flow.

 They have low shear – Internal gear pumps have low shear, which offers a slow, consistent, non-pulsating flow that does not harm the fluids or negatively affect their quality.

They are leak-free – Owing to tight clearances between the gears and casing and advanced sealing mechanisms, internal gear pumps offer leak-free operations. Additionally, they also come in various seal options, such as single and double mechanical seal configurations, to adapt to the requirements of applications. This capability is particularly crucial in industries where operators must handle hazardous or environmentally sensitive fluids, such as pharmaceuticals and chemicals.

They can handle high-pressure environments - Internal gear pumps are designed to operate at higher pressures without any performance issues, making them suitable for demanding applications such as hydraulic power units and fuel injection systems.

They are low maintenance – With simple working mechanisms and minimal fixed and moving parts, internal gear pumps require fewer maintenance sessions.

Viking Pumps – delivering excellence since 1911

So, as mentioned above, internal gear pumps have several benefits. However, these benefits can be reaped only when one of the best pump brands is chosen. One such trustworthy and reputed brand is Viking. The brand has been a known name in the positive displacement pump space since 1911. Viking pumps boast of displacing more than 1400 kinds of fluids, including aggressive, ultra-pure and solid-laden ones. The brand has over 245 authorised distributors in 68 countries to provide application support and service.

Viking's Universal Seal pumps are designed to work with a large number of applications and can handle pressure up to 200 psi. If an operator needs to run the pump at even higher pressure, they can reduce the operating speed, and the fluid will be displaced without a problem. Like most internal gear pumps, Universal Gear pumps work operate equally well in either direction, and can operate under suction lift conditions. These pumps are offered in several versions (suitable for light, medium, and heavy-duty applications), and operators can pick the ones that are compatible with their application/s.

The brand Viking Pump is a unit of IDEX corporation, which has delivered industrial equipment for all kinds of industries, including military, food & beverage, oil & gas, chemical and plastic. Their portfolio of pumps is large, and one can find a reliable and robust solution for their specific needs.
