The rotary gear pump is a type of positive displacement pump that ensures constant fluid pumping for each revolution.
Available in different types, materials, and sizes, rotary gear pumps are ideal for a wide variety of applications.
If you are planning to install a rotary gear pump, it is important to first learn everything about it. From the basics of rotary gear pumps to working and applications, there is a lot to know about the pump.
In this blog, we will explore:
Let's begin with the definition of a Rotary Gear Pump.
Belonging to the group of positive displacement pumps, the rotary gear pump consists of a rotor and ideal gear assembly used to move fluids continuously in various sectors.
Rotary gear pumps are widely used for continuous liquid flow, high viscous fluid transfer, and liquid pumping under very high pressure.
Let’s explore how a rotary gear pump works.
Rotary gear pumps consist of rotor and meshing gears that together rotate to pressurize and move liquids forward. These rotating components develop a liquid seal with a pump casing to create a suction at the pump inlet.
The liquids being pumped enter inside the pumps and are enclosed within the gear cavities rotating inside the pump.
Later, gears rotate and push the liquid forward to let it discharge from an outlet port.
This process is repeated consistently to create a constant and smooth flow.
Now, let’s look into the features of rotary gear pumps.
Rotary gear pumps have various features that make them reliable options for many industrial sectors.
The compact design and sturdy construction of the pump make it highly efficient in maintaining high-pressure fluids.
SS rotary gear pumps are constructed using stainless steel materials that help the pump handle corrosive and harsh liquids with ease.
Higher durability and efficiency of the pump reduce component damage and chances of leakage, resulting in long service life with minimum maintenance.
To add more, these pumps generate very low noise for trouble-free operation.
Next, let's talk about different types of rotary gear pumps.
Here are the most common types of rotary pumps:
1 External Gear Pump
2 Internal Gear Pump
Let’s get into the details.
The external gear pump consists of 2 interlocking gears supported by separate shafts.
The first gear is driven by a motor, which drives the second gear. The pump shaft in the external gear pump is supported by bearings on each side of the casing.
When gears teeth become interlocked, the fluid volume gets reduced, and liquids are forced out of the discharge point.
Both internal and external gear pumps work the same way; however, the internal gear pump consists of 2 different size interlocking gears, with one rotating inside the other.
The one rotating inside is the largest gear, i.e., an internal gear, whereas the smaller gear is mounted off-center.
This pump type is designed to interlock with the rotor in a way that gear teeth engage at one point.
At Jay Khodiyar Engineering Works, we provide different types of Rotary Gear Pumps in different variations.
One of them is the SS Rotary Gear Pump.
The stainless steel rotary gear pump is manufactured using high-grade raw material and meets the highest quality and hygiene standards.
It is the best choice for transferring corrosive, hygienic, and viscous liquids in various industries. SS rotary gear pump has unique features such as easy cleaning, low maintenance, sturdy construction, trouble-free operation, and corrosion resistance, which the clients highly appreciate.
Now that we've covered various types of rotary gear pumps, let's determine the key difference between them.
Tabulated below are the key differences between external gear and internal gear pumps.
|External Gear Pump||Internal Gear Pump|
|Rotor shafts are supported by four bearings.||Rotor shafts are supported by one or two bearings.|
|Compact pump design||Bulky pump design|
|Larger outlet size||Smaller outlet size|
|Gear design includes spur, helical, or herringbone||Gear designs includes only spur|
|High pressure pumping||Moderate pressure pumping|
|Medium to low temperature handling||High temperature handling|
|Ideal for both high and low viscous fluids.||Ideal for high viscosity fluids|
|Used for pumping water, light oils, chemical additives, resins or solvents.||Used for pumping water, solvents and fuel oil, asphalt, chocolate, and adhesives./td>|
At this point, it's time to discover the applications and advantages of rotary gear pumps.
Rotary Gear Pumps can easily handle various types of viscous liquids & chemicals in diverse industries, including food, chemical, and oil storage installations, power plants, steel mills, refineries, and more.
