What are Gear Pumps?
Gear pumps are a type of rotary positive displacement (PD) pump used to move fluids by repeatedly enclosing a fixed volume using interlocking cogs or gears. They are a reliable and efficient choice for a wide range of applications, including hydraulic fluid power, extrusion, hot melt adhesives, chemicals, resins, oils, and ink. Gear pumps are available in a variety of sizes and designs, including internal eccentric, external (helical gear), medium duty, heavy duty, and extreme duty.
They are also capable of pumping fluids with high viscosity and harsh liquids. Gear pumps are known for their ability to stabilize pressure, raise output, and cut scrap. To ensure performance, it is important to select the right gear pump for the job. Gorman-Rupp, PSI-Polymer Systems, Parker, and Blackmer all offer dependable gear pumps for a variety of applications.
Construction and Components of Gear Pumps
Gear pumps are an essential component of many machines and are used in a variety of industrial settings. They are reliable and efficient pumps that are used to move fluids such as oils, lubricants, and fuels. As such, it is important to understand the construction and components of gear pumps in order to ensure they are functioning properly and safely.
Gear pumps are composed of two meshing gears that are enclosed in a housing. The gears are machined to ensure tight tolerances, and they are mounted on shafts that rotate within the housing. The gears are designed to create a chamber between them, and as they rotate, the chamber fills with fluid and is pushed out of the pump.
The main components of gear pumps include the inlet, outlet, drive shafts, gears, and housing. The inlet and outlet are located at opposite ends of the pump and are used to provide suction and pressure. The drive shafts are connected to the gears and are responsible for providing the rotational motion of the gears. The gears are the primary component of the pump, as they are responsible for creating the pumping action. Lastly, the housing encloses all of the components and is sealed to prevent any leaks.
Understanding the construction and components of gear pumps is essential for keeping them functioning properly. These components must all be properly maintained to ensure optimal performance and longevity. Be sure to inspect your gear pumps regularly for any signs of wear or damage, and always follow manufacturer instructions for proper maintenance.
