Slurry Pump vs. Water Pump | Why & Where Slurry Matters

Slurry pumps and water pumps are not one and the same, which rings true for other pumps as well. Each serves a different purpose, which helps to inform why they’re not interchangeable systems. But why, exactly, is a slurry pump necessary over a standard water pump in certain, specific applications? Read on for the full answer.

Know the Difference Between Slurry and Water Pumps

As mentioned, a slurry pump differs from a water pump in many key ways. First, slurry pumps and water pumps (as their names suggest) pump different materials. Slurry pumps pump mixtures of fluids not present when pumping hot water, hot oil, or thermanol, which can include or involve gravel, copper, sand, alcohols, acids, petroleum, abrasive mixtures, and more. Slurry pumps are specially made to handle these abrasive and/or caustic materials, having replaceable, durable, and robust pump parts. 

On the other hand, hot water pumps are able to bear high temperature pressure, but don’t have the hydraulic capacity to pump solid or slurry particles effectively. Hot water pumps also lack the ability to stand up to the highly abrasive and corrosive nature of slurries. 

Why a Slurry Pump Works for Intended Use

What makes a slurry pump so effective at handling slurry? It has many wear-resistant properties, including a bigger impeller diameter, bearings, shafts, and internal system. It also typically boasts heavy-duty construction—much more so than standard water pumps possess. 

Due to this, slurry pumps can transport solid and slurry materials more effectively and efficiently. The other core component to slurry pump success is the utilization of centrifugal force. Centrifugal force propels material(s) outward from the center of the pump. Centripetal force does the opposite: It propels material(s) toward the pump center. However, slurry pumps have to perform on a centrifugal basis. This is due to the way in which forces produce velocity to the slurry, which fast tracks material transportation. Operationally, a centripetal pump would render ineffective for slurry, causing the slurry and solids to conglomerate together rather than flow freely. 

Means for Slurry Pump Implementation

There are three main ways to pump slurry based on what the specific situation calls for. These are semi-dry, dry, and wet. Semi-dry installations are almost exclusively used for dredging applications that utilize horizontal pumping orientation. Dry installations are when pump drive and bearings stay out of slurry, and the “wet” end is free from liquid and stands on its own. Here, the wet end comprises the impeller, shell, suction liner or hub, and shaft sleeve. For wet installations, which Vulcan Pumps specializes in, the slurry pump and drive are wholly submersible. This is essential for a range of slurry pump applications, including those done underwater.

Slurry pumps are used in a variety of industries, from mining to handling corrosive or abrasive materials. It is important to understand the different types of slurry pumps available and how they operate so that you can choose the right pump for your application. Let’s take a look at the different types of slurry pumps and their uses.

Types of Slurry Pumps

There are four main types of slurry pumps: centrifugal, submersible, vertical, and positive displacement. Each type has its own advantages and disadvantages, depending on the application. Let’s explore each type in greater detail.

Centrifugal Slurry Pumps:

These are the most common type of slurry pump because they are relatively easy to install and maintain. They use centrifugal force to move solids through a pipeline and can be used for both high-pressure applications like sewage treatment or low-pressure applications like dredging. They are also commonly used for tailings transfer systems in mining operations.

Submersible Slurry Pumps:

Submersible pumps are installed underwater and can handle both solid particles as well as liquid slurries with ease. These pumps are ideal for dewatering applications where high pressure is needed, such as treatment plants or pumping out flooded areas. They also work well in applications where large amounts of solids must be moved quickly without clogging up the system.

Vertical Slurry Pumps:

Vertical slurry pumps have an upright design and provide more flow power than horizontal models due to their increased head pressure capabilities. They also require less space than horizontal models, making them ideal for confined installations like wastewater treatment plants or construction sites where space is limited. These pumps typically have higher flow rates than other types as well, making them great for larger-scale operations involving high volumes of material transfer.

Positive Displacement Slurry Pumps:

Positive displacement pumps move liquids using positive suction rather than relying on impellers like other pump designs do. This makes them ideal for handling thick liquids or slurries containing chunks or lumps which could clog up other pump designs easily. These types of pumps offer excellent performance when dealing with heavy loads, so they are often found in industrial settings such as oil refining plants or sugar mills where sticky substances need to be moved quickly and efficiently without damage to the pump itself.

No matter what type of application you need a slurry pump for, having an understanding of the different types available will help you make an informed decision about which one is best suited for your needs. Consider factors like pressure requirements, size limitations, material handling capabilities, and cost when making your selection so you can ensure you get a reliable solution that meets all your needs while still staying within budget. With this guide in hand, you should have all the information necessary to determine which type of slurry pump will work best for your specific needs.
