What’s in your slurry? When it comes to choosing the right slurry pump for your application, you have a few options to choose from. Learn more about slurry pump types, what materials suit each pump best, and how to find the right type.

Slurry types

In theory, any solid can be hydrotransported. However, particle size and shape can be limiting factors depending whether they can fit through pump passages without causing blockages. Within the broader “slurry” category are four slurry classifications that determine how to best choose appropriate slurry pumps.

Class 1: Mildly Abrasive
Class 2: Slightly Abrasive
Class 3: Significantly More Abrasive
Class 4: Highly Abrasive

It may be no surprise Oil Sands pumps are ideal for moving highly abrasive class-four slurries. Because slurry pumps are made specifically to hydrotransport large-particle solids, they also ensure better wear performance in harsh conditions. But there’s more to choosing a pump than knowing the type of slurry it will move.

Four centrifugal slurry pump types

While centrifugal slurry pumps are well-known for their use in the Oil Sands, many have additional applications.

  1. Hydrotransport — Hydrotransport pumps cover a wide range of applications because moving slurry is hydrotransport. These slurry pumps are best used with water-based solutions and are often used in dredging.
  2. Tailings Transfer — Tailings Transfer pumps are best suited for transporting tailings, or the finer abrasive particles that result from hard rock mining, like mud and ore particles, as well as associated chemicals used in the mining process. Pending specific applications, LSA, LCC, and MDX pumps from GIW are all useful for tailings transfer.
  3. Cyclone Feed — Like tailings pumps, cyclone feed pumps are also used in hard rock mining and are similar to hydrotransport pumps as they’re applicable to dredging operations. In the cyclone feed market, these pumps are used in all stages of scalping or separating solids by particle size. GIW’s LSA and MDX slurry pumps are widely used for cyclone feed applications, depending on the required size range.
  4. Flotation Froth — Transporting froth using a slurry pump is a unique application in that the air contained in froth can negatively impact pump performance. This also means it’s difficult to predict pump performance life for these applications. Due to these factors, oversized High-Volume Froth (HVF) pumps, which remove air from froth, are necessary for froth applications.

Choosing the right pumps for specific slurries can help pump owners avoid unnecessary maintenance, repairs, and related downtime. In addition, proper pump applications make for safer work environments, offering those working on or around pumps peace of mind. Perhaps best of all, purpose-chosen slurry pumps also have longer wear lives, boosting owners’ bottom lines.

Still don’t know which pump type is right for your application? Those with unique slurry pumping requirements need not fear. Based on data from over 3,000 centrifugal slurry pumps, GIW’s proprietary pump selection program called SLYSEL can help prospective pump owners get what they need down to their exact specifications. Plus, SLYSEL can help pump operators ensure they’re operating pumps correctly — from properly calculating performance curves and pipe friction loss to evaluating other operational factors and pumps themselves — reducing room for error and maintaining pump longevity.

A Guide to Choosing the Right Slurry Pump and Filtration ...

The slurry business is a complex industry filled with myriad physical, economic, and legal considerations. As a project manager, choosing a proven, American-made slurry system can go a long way towards preventing clogs and breakdowns, ensuring your system remains a profitable and resilient wastewater solution.   

However, not every system is built to handle the same loads or manage slurry in the same way. Understanding the different slurry pump and filtration system options on the market will help you find the right system for your project.  

Choosing a Slurry Pump

 

Slurry pumps come in various lengths, elevations, and materials. Be sure the pump you choose will perform at your specifications and can integrate well into your existing system.  

Types of Slurry Pumps

 

Not all slurry pumps are used for the same purposes or at the same processing stages. The first thing to consider when browsing the pump market is what kind of pump you need—horizontal, vertical, or submersible.   

Horizontal Pump

 

Horizontal slurry pumps move slurry parallel to the ground and handle highly abrasive or corrosive slurries with ease. Because they’re so durable, horizontal pumps are popular in heavy industry, including mining, metallurgy, and power generation.  

Vertical Pump

 

Vertical pumps are used to transport materials to different elevations. Often (but not always), a vertical pump will be partially submerged in a slurry pool to transport its contents to different parts of the project site. 

Submersible Pump

Submersible pumps are fully immersed in slurry. They are specially designed and built to handle the rigors of operating within a liquid, but they can degrade quickly, especially if your slurry is highly acidic.  

Slurry Pump Materials 

Consider what material you will be pumping. Some pumps are perfect for moving sand and mud, while others are more suited to processing sludge and other waste. Before making a purchase, ensure the pump’s material can handle the density, pH, viscosity, and temperature of the material you process.  

Flow Rate

 

Different pumps process materials at different speeds, and the flow rate that’s best for your system will depend on what materials you process and during what stage of processing the pump will be used. For example, slurries that contain a lot of solids need to be pumped at a higher flow rate to prevent material from settling inside the pump and its connected hoses.  

Discharge Head

 

Any slurry pump you choose needs to be able to exceed the discharge head of your entire discharge system; otherwise, the system will not operate at peak efficiency and may suffer abrasion.  

Knowing the answer to these questions before you make a purchase will help you choose the best pump for your operation and avoid the costs associated with an inefficient or damaged slurry system.  

Integrating Your Pump into a Wastewater Filtration System

 

After you’ve selected a pump, you can pair it with a new or existing filtration system to optimize your entire water treatment process. Full Circle Water offers many different water filtration systems, including industrial slurry silos, portable filtration plants, and rapid resettlement systems.   

All-in-One Plants

 

All-in-One slurry silo filtration systems are turnkey solutions designed to provide efficient wastewater decanting regardless of the type of operation you run. Full Circle Water’s All-in-One system was designed based on feedback from over 600 stone fabricators and is among our smartest and most effective slurry silo plants.  

Trailer Plants

 

Trailer filtration systems are designed to offer clean water on-the-go. Their compact, portable design makes them ideal for projects that need to set up or tear down quickly.  

Rapid Settlement Systems

 

Wastewater decanting is one of the most important phases in any slurry management system. Rapid resettlement systems are designed to recycle up to 90 percent of wastewater and feed it back into production, ensuring your operation never has to wait for water again.
