Quick guide to select Internal Gear Pump.

With the variety of pumps available today, it is sometimes difficult to determine which pump is best for a particular application. Which one can handle the viscosity of the fluid? Are you creating the right flow and pressure? To make sure you're getting exactly what you need, it's a good idea to contact a savvy pump engineer, but this post will give you an understanding of the internals and characteristics of internal gear pumps so you can check: It is suitable for your application.

General description of the internal gear pump

The internal gear pump has the ability to pump different types of fluids at different viscosities and temperatures. The internal gear pump uses two gears to move the fluid. There is a rotor gear on the outside and a smaller idler gear on the inside.

HOW IT WORKS

When the rotor gear (outer) rotates, the idler gear (inner) is driven. When the idler gear does not contact the rotor gear, the liquid enters the pump and travels through the casing to the discharge side of the pump. Here, the gear teeth engage and the fluid is forced out. Of the bomb.

What are they good for

The internal gear pump is ideal for high viscosity fluids. It is also excellent in situations where low NPSH is required. Since there are only two moving parts, they require significantly less maintenance.

Not very good

The internal gear pump does not work well with large solids. Due to the small tolerance, large solids can easily damage the pump. It can handle some suspended solids in abrasive fluids, but this can wear out the pump and reduce its performance.

Best application

This is a brief list of applications where an internal gear pump can be used.

·         Food (corn syrup, oil, nut butter, chocolate)

·         dairy product

·         Personal care products (paste, cream, soap)

·         A wide range of oils and lubricants

·         Paint, pigment, ink

The internal gear pump is one of the most versatile pump types available. Consult an experienced engineer to choose the right pump for your job.
