Quick and Easy Guide To Progressive Cavity Pumps

Let's address progressive cavity pumps (PC), which fit into the cheerful rotating displacement pump family. The PC pump is often maligned as the pump of last resort. However, the PC pump is an excellent choice as the fluid viscosity increases beyond the efficient range of centrifugal pumps.

It is also beneficial in applications where the fluid is abrasive and/or shear sensitive. In agricultural applications, the pump is used to move fruits or berries with little to no harmful effects on the product.

What is a Progressive Cavity Pump?

A Progressive Cavity Pump is a sort of positive displacement pump which comprises a rotor and stator. The metal rotor drives the stator through the chain and starts to fill the cavities with equivalent measures of liquid which then gets pushed through the pump outlet. They are an exceptionally hearty siphoning framework that guarantees maximum performance and dependability.

How Does a Progressive Cavity Pump Work?

The rotor inside the pump rotates inside the stator, as it turns, the cavities inside the stator are loaded up with the cycle media and are conveyed towards the pump outlet under tension. The pockets of liquid have a set volume that concludes the volumetric stream pace of the pump, this is directly relative to the rotational speed of the rotor and results in low degrees of shearing and next to zero heartbeats.

Progressive Cavity Pump Advantages:

Good for solids handling and can also handle air entrained, multiphase, and abrasive liquids
Excellent choice for high viscosity applications
Offer low net positive suction head required
Excellent self-primer pump
Do not vapor lock
Offer high accuracy as a metering pump
A given size/model of pump installation will handle a wide range of viscosities very well
Reversible direction/ bi-directionally. The pump can be operated in either direction, and the suction becomes the discharge and vice versa
Quiet operation

BEST APPLICATIONS

These pumps are used in a great range of applications from wastewater treatment to oil, to food and beverage. Here are only a couple of the applications where a progressive cavity could be found:

Slurry and sludge transfer
Oils
Beauty care products, creams, and lotions
Paint, stain
Adhesives
Fruits and Vegetables

The progressive cavity pump is ideal for many applications across a wide spectrum of industries. Think it might be right for yours?

Top 5 Applications of Spent Wash Transfer Pumps You Should Know

Every drop of spent wash—the dense, high-temperature by-product of ethanol and sugar production—tells a story of complex industrial movement. Behind the scenes, powerful pumps shoulder the burden of transporting this heavy, often corrosive liquid without clogging, stalling, or giving in to wear. And at the heart of this operation lies the spent wash transfer pump —an essential component of efficient and sustainable industrial processing. Used extensively across distilleries and agro -based industries, spent wash pumps play a pivotal role in maintaining flow consistency and preventing environmental damage. But their utility extends far beyond just moving liquid. Designed using positive displacement pump princi ples , these machines are built to handle the most demanding fluid transfer tasks. In this blog, we dive into the top 5 applications of spent wash transfer pumps —so you can better understand their significance, and why choosing the right one is critical fo...

Benefits of Using Magma Massecuite Pumps in Sugar Industry

The course of sugar production starts with the arrangement of cane for juice extraction. Stick is cleaned by spreading it into disturbing transports and going through planes of warm water, clearing off leaves, soil, and rock particles. Beetroot is hacked before juice extraction. The course of juice extraction includes cutting, destroying, and pressing cane and beet with the assistance of roller factories. The separated juice is a dull green, dinky acidic fluid requiring bubbling for additional handling. Lingering bagasse is shipped off boilers for use as fuel for power age. This cane juice is treated with intensity and milk of lime to remove acidity. The treated juice is then additionally warmed and shipped off for sedimentary cleaning. The clear juice is dissipated to a syrup stage, branched by sulfur dioxide then, shipped off vacuum prospects focus and sugar grain development. Crystals are created to the ideal size and the solidified mass is then dropped in crystallizers to deplete...

Why Screw Pumps Are the Best Choice for Industrial Applications

When it comes to industrial applications, pumps are the unsung heroes. They're the workhorses keeping everything flowing, and a pump failure can grind entire operation to a halt. That's why choosing the right pump technology is crucial. And if you're looking for reliability, efficiency, and versatility, it's hard to beat the performance of a screw pump. But why are screw pumps so often favored? Let's delve into the reasons explaining why these pumps are a top choice, especially when you're considering options from leading industrial pump manufacturers like Risansi Industries. Gentle Pumping Action for Delicate Materials One of the key advantages of screw pumps is their gentle pumping action. Unlike centrifugal pumps that use high speeds and impellers, screw pumps rely on the rotating motion of one or more screws to move fluid. This creates a smooth, continuous flow with minimal shearing force. This gentleness is particularly valuable when handling sen...
