Submersible pumps can be used in a vast and varied number of applications. It’s one of the core reasons they can seem like such complicated pieces of equipment. Saying that, for the average person, a submersible pump will be used for one of the following three applications.
Irrigation
From efficiently watering the garden to draining water from ponds and aquariums, the submersible pump is a key component of a thoroughly irrigated and healthy garden or piece of land. They are often implemented into rainwater harvesting systems as they can take the reliance off mains water and help people save money in the long term.
Pumping from wells and boreholes
The submersible pump is ideal for pumping water out of wells and boreholes. Efficient at pumping water up from great depths, the design of a submersible pump allows it to sit in tight or confined spaces and pump water without using too much power.
Draining Unwanted Bodies Water
A submersible pump is suitable for draining flood water and other unwanted bodies of water. Often situated in basements and other areas that experience frequent flooding, the automatic function on an electric submersible pump allows you to clear water without being present.
The Oil Industry
Probably not the main reason you are browsing this guide however, a submersible pump is a key tool in the process of pumping oil from ground deposits to treatment refineries.
Yes, you can run a submersible pump continuously for as long as you require if you have the suitable source of water. Saying that, it is imperative that you do not run a submersible pump dry. Running the majority of submersible pumps dry can cause significant damage to the inner motor and components. That’s why we recommend purchasing a sump pump with a float switch for automatic use.
As mentioned at the beginning of this guide, there are many different types of submersible pumps. The two most common types are 1. Drainage submersible pumps and 2. Wastewater/sewage submersibles. Ultimately, the only difference between the two is the type of water or waste they can pump.
Drainage Submersible Pumps
The most common use for this type of pump is drainage. Manufacturers such as Grundfos and KSB produce this type of pump and they can be used for many different purposes. Most commonly they are used to clear excess water from cellars or basements that are prone to flooding. If you purchase this type of pump then please be aware that you need to pump the water to a safe and suitable location. You can also purchase a ‘lifting station’ which can safely discharge water away from the property and store the water in a tank.
Wastewater/Sewage Submersibles
When you plan to pump wastewater or sewage, you will need to consider purchasing something a little more heavy duty. The Calpeda GXCm 40b is the perfect dirty water pump. Pumps like these are suitable for applications where there are particles in the water, such as when emptying septic tanks or removing wastewater from industrial processes.

Replacing a submersible pump may seem like a difficult and complicated task, but if you follow the tips below then you should be sorted in no time.
Take a Look at the Old Pump
If you’re replacing a broken submersible pump, then take a look over the old installation. Firstly, the old pump should have a label that details the specification of the pump. This should make it easier to decipher which pump type you need when browsing online. Another component to note down is the size diameter of the discharge pipe. Make sure to check that the pump you’re buying online is the same size and shape.
Choosing the Right Float Switch
A common mistake is buying the wrong type of float switch. There are two types available. They are:
Vertical Switch Pump - this switch activates the pump by moving straight up. Often used in smaller pumps, this float can be used in smaller 10-inch diameter submersible pumps.
Contact us to discuss your requirements of Submersible Slurry Pump. Our experienced sales team can help you identify the options that best suit your needs.
Tethered Switch Pump - this switch activates the pump by moving in a diagonal direction upwards. Only available in pumps with a 14 inch (or above) intake, these floats are often used in heavy duty submersible pumps.
Battery Backup System
Submersible pumps are often used in an attempt to protect homes from flooding. If you do intend to leave a submersible pump running during a flood, just remember that electricity may be cut from your home at any time. If this is the case, make sure you purchase a pump with a backup battery system. A backup system simply offers peace of mind. Can you imagine how it would feel to return home after a flooding event to find that your pump ran out of power?
Consider the Pumping Distance
Submersible pumps will come in all different shapes and sizes. One of the key differentiators is the power capability of each pump. Consider how far you want to pump liquid. The further you want to pump the liquid, the more powerful you will want the pump to ensure flow rate.
Consider the Viscosity of the Liquid
In the same vein, consider the viscosity of the liquid you intend to pump. The thicker the liquid, the more difficult it will be to pump and maintain flow rate. Thin liquids like clean water will be relatively ok with a low power pump. But if you intend to pump dirty water then you will need a pump with a lot more power.
Before buying and using a pump, take a look over these Dos and Don’ts. Most will be common sense, but a few will ensure your pump stays in full working order. On a further note, please take the time to thoroughly read the installation and operation manual provided with each pump.
DO:
Check the Pump isn’t Damaged Prior to Use
If you’re buying second hand or renting a submersible pump, please take the time to ensure the pump is not damaged prior to use. Take extra time to ensure cables are not frayed.
Connect to an Appropriate Power Supply
If you intend to use the pump during a flood event, please make sure that you connect to an appropriate power supply. Ensure the power supply is well away from floodwater.
Make a note of the Pump Type before Fitting in Sump
If the pump fails while underwater, you will thank your lucky stars that you noted down the pump type and model.
Make sure the Float Switch can Move Unrestricted
The main cause of submersible pump failure is the pump running dry. This is often caused by a faulty float switch.
Make sure the Pump Filter is Cleaned Regularly
Once a month make sure you take the pump filter apart and give it good clean. This will keep your pump in full working order.
DON’T:
Lower the Pump Down with the Power Cable
If the power cable frays when lowering the pump down then you are guaranteed to break the pump. Electricity and water do not mix. Take the time and care to lower the pump down and secure in place.
Allow Water to Freeze around the Pump
When water freezes it expands. If the water freezes inside of the pump it could damage the inner workings of the pump.
Leave the Top of the Sump Open or Uncovered
A submersible pump is only hermetically sealed if the whole of the pump is correctly closed and covered.
Allow the Pump to Run Dry
The most important thing to not do is let the pump run dry. Submersibles are designed to pump water at all times and must have a suitable water supply. Purchase a submersible with a float switch to ensure automatic cut off.
Slurry pumps (and submersible slurry pumps) are designed for pumping thick materials that can consist of such things as slurries, sand, gravel, mud, crushed rock, muck, manure, and many other highly viscous materials. Typically, a slurry is a mixture of a given material such as crushed rock and water. A slurry pump is purpose built with robust pump components and mechanical seals for pumping abrasive slurries and viscous fluids from the material source, into and through the pump, and downstream to its final destination.
Slurry pumps are inherently rugged by the nature of what they do and are capable of pumping high viscous and high specific gravity solid-laden slurries without clogging. This is why a standard centrifugal pump will often not move highly abrasive slurries over long periods of time.
The non-clogging aspect of a slurry pump design is one of the most critical differentiating factors compared to other pump types. These pumps usually feature heavy duty construction and high efficiency impellers and perform in some of the harshest environments, including dredging, oil & gas, power generation, mining, wastewater treatment, frac sand pumping, and many other industries.

The following list of 8 significant considerations is to help you understand your pump application necessities in relation to selecting the best-suited pump for your heavy duty abrasive applications. The greater the viscosity, particle sizes, specific gravity, abrasion, and other important fluid and non-fluid characteristics make selecting a pump more difficult because these factors play into the situation at a greater level of importance, making the following application specifics even more critical.
The key reason these specialized centrifugal pumps offer reliable performance lies in their ability to transport large volumes of slurry with relatively low energy consumption. The centrifugal action, where a rotating impeller creates a flow by converting mechanical energy into kinetic energy, allows for continuous movement of slurries over long distances with reliable operation. Unlike other pump types (including twin screw pumps and other positive displacement pumps), centrifugal slurry pumps can handle large particles, high solids concentrations, and highly viscous fluids without clogging or excessive wear.
Their robust design, including materials like hardened steel or elastomers for critical wear pump components (such as pump shaft, inlet valve, outlet valve, suction hose and pumping chamber), ensures longevity and minimizes downtime, which is crucial in industrial operations where any disruption of fluid flows can lead to significant financial loss. Centrifugal slurry pumps also have the flexibility to be customized for specific applications, such as varying impeller designs or the use of liners to match the slurry’s characteristics (including corrosive liquids or abrasive particles), ensuring superior performance and extended service life.
In dredging, for example, these pumps help transport large volumes of sediment, sand, and rocks, perfectly suited to heavy duty applications, land reclamation and navigation maintenance. In mining, they are used for transporting ore slurry in mineral extraction processes. Their reliability, versatility, and ability to move challenging materials make centrifugal slurry pumps indispensable in any slurry applications.
A slurry is essentially a mixture of fluid and fine solid particles, and its composition can vary widely depending on the specific application. Generally, slurries are classified into two categories: non-settling and settling. Non-settling slurries consist of very fine particles and have low erosive wear properties, making them easier to pump. On the other hand, settling slurries are formed by coarse particles and have higher wear properties, which can pose more challenges during pumping. The composition of a slurry can include a diverse range of materials such as manure, cement, starch, or coal suspended in water or other liquids. Understanding the specific composition of your slurry is crucial for selecting the right pump and ensuring greater efficiency slurry pumping.
Slurries possess several distinct properties that significantly affect their behavior and handling, making standard pumps inappropriate. These properties include:
Understanding these properties is essential for selecting the right pump and designing an effective slurry pumping system. Each property influences the choice of pump type, material of construction, and overall system design.
Centrifugal slurry pumps are specifically designed to handle the heavy and abrasive nature of slurries. Key features of these pumps include:
The design and construction of a centrifugal slurry pump are critical to its performance and longevity. By incorporating these robust features, centrifugal slurry pumps can effectively handle the challenges of pumping abrasive and heavy slurries, ensuring reliable and efficient operation in various slurry pumping applications.
EDDY Pump Product Categories
If you are pumping slurry, brines, high solids, extremely viscous material, paste, high abrasives (sand & gravel), and material filled with solids, then you found the best-suited pump for the job. Go to: https://eddypump.com/ or Call Us!
Pump Orientation Options
When choosing a slurry pump for an application, there are two categories of slurry pumpsbased on product orientation; vertical pump and horizontal pumps. Vertical or horizontal refers to the shaft orientation. Both pump orientations have their advantages and disadvantages. Vertical pumps help to reduce the space required for pump location and can be maneuvered into smaller spaces, whereas horizontal pumps are the most common pump orientation.
The EDDY Pump is considered one of the premier self-priming high viscosity and high specific gravity pumps in the world and has been designed specifically for demanding applications that require the transfer of thick, abrasive, heavy solid laden materials. The non-clogging design of the pump includes an enlarged wetted path and recessed rotor. This allows the pump to move large volumes of viscous material through the pump without clogging and causing downtime to your application.
Premier Pump Design
The unique design of the recessed rotor creates an Eddy Current as it spins inside the volute. This method of displacing fluid via the uniquely designed recessed rotor creates a vortex (a circular current of fluid) at the pump inlet that assists with drawing the material to be pumped into the volute, exiting the pump discharge, and pumping the material downstream of the pump to the desired location. The Eddy Current also keeps particles and solids maintained in suspension which is critical when pumping high viscous, solid-laden material. The EDDY Pump’s ability to pump concentrated solid matter is perfect for moving viscous materials with as much as 40-70% solids by volume; an impossible task for a lot of traditional pump types. The EDDY Pump can also pass extremely large solids that are almost the size of the liquid inlet and liquid discharge of the pump; these results are beyond the scope of what most other traditional pumps can achieve.
Low Cost of Ownership
An important factor when choosing the best pump for your application goes beyond whether or not the pump can meet the application requirements; there is also the subject of Cost of Ownership and how much it costs you to operate your pump over the course of the pump’s lifetime. Due to the EDDY Pump’s ability to pump high viscous and high specific gravity materials with the volume of very high solid and extremely low water content, the cost to pump the material is drastically reduced. The accruing cost of water that goes along with using pumps that require a high water content to move viscous materials dig very deep into your profits.
Materials of Construction
The EDDY Pump is made of the highest quality materials and is extremely rugged, abrasion resistant, chemically compatible with most fluids, and capable of withstanding a great deal of punishment that is typically inherent in abrasive, high viscosity, and high specific gravity, slurry applications.
