Where are gear pumps generally used?

Gear pumps are used in various sectors due to their toughness, efficiency and ability to move different viscosities. They function by trapping a liquid between the teeth of one or more gears or rotors and the pump casing, pushing it toward the outlet.

Given this problem background, let’s now turn to some practical applications of gear pumps:

1. Chemical Installations: Gear pumps are employed in chemical industries for handling fluids such as high viscosity or corrosive chemicals. For instance, they can be made from stainless steel, Hastelloy or even non-metallic materials that resist chemical attack thus making them ideal for use in transferring acids, alkalis, solvents and other process chemicals. Additionally through expansion dosing and metering equipment is supplied with precise amounts of chemicals which should be mixed into these substances.
2. Oil Industry: In the oil and gas industry gear pumps are commonly used during upstream (exploration) as well as downstream processes (refineries). Therefore onshore exploration production platforms employ them for pumping crude oils, fuel oils, lubricants plus any other petroleum products whereas refineries majorly utilize them for moving crude oils and other fluids having high viscosities around facilities. Viscous fluid flow is characterized by efficient operation of these devices during circulation of lubricating oil as well as while handling highly viscous crudes.
3. Hydraulic Power Applications: Gear pumps form crucial parts of hydraulic systems which transmit power to various machines and equipment. It ranges from automotive steering systems through industrial machinery where reliability within constant flow is critical. Thus gear pumps have pressure generation capacities so that they can operate hydraulic rams motors actuators.
4. Machinery Requiring Precise Fluid Metering or Transfer: Gear pumps offer precision hence they find application in machines requiring exact fluid metering like injection moulding machines; chemical mixing plants; food processing equipments etc. Their significance lies in their ability to deliver consistent quality by accurately repeating fluid flows over time which ensures accuracy and avoids wastages.

More Uses: Apart from the common applications stated above, gear pumps find use in:

• Food and Beverage Industry: For transferring or dosing thick foodstuffs like molasses, chocolates and concentrates.
• Pharmaceuticals and Cosmetics: For accurate dosing of components, handling fragile fluids, as well as in making creams, jellies and drugs.
• Pulp and Paper Industry: For metering additives into the paper process as well as handling heavy materials such as black liquor.
• Agriculture: Spraying and distributing fertilizers, pesticides and herbicides.
• Automotive Sector: As oil and transmission fluid pumps in vehicles.
• Manufacturing and Processing: Cooling /lubrication systems; paint circulation; resins/polymer processing.

The diversity of gear pumps combined with their various designs allows them to meet specific requirements across industries, from simple discharge operations to complex fluidic management systems. This has led to their widespread acceptance for tasks associated with efficient handling of fluids with accuracy.
