Submersible Pump Accessories You Need to Know About

Submersible pumps are versatile and reliable tools used for a variety of applications, from draining flooded areas to pumping water from wells. However, to get the most out of your submersible pump, it's essential to understand the various accessories that can enhance its performance and longevity. Just like a wet and dry vacuum cleaner offers different attachments to tackle diverse cleaning tasks, submersible pumps can be paired with accessories such as float switches, check valves, and discharge hoses to optimise their functionality and extend their lifespan.

In this article, we will explore the key accessories you need to know about to optimise your submersible pump's functionality. 

1. Float switches 

One of the most crucial accessories for a submersible pump is a float switch. Float switches are used to automatically turn the pump on and off based on the water level. This not only prevents the pump from running dry and potentially getting damaged but also ensures that it operates only when needed, saving energy. There are two main types of float switches: tethered and vertical. Tethered float switches are suitable for larger areas as they have a wider range of motion, while vertical float switches are ideal for confined spaces due to their compact design. 

2. Check valves

Check valves are essential for preventing backflow in your pump system. They allow water to flow in one direction only, ensuring that once the water is pumped out, it does not return to the sump pit or well. This is particularly important in systems where the discharge pipe runs vertically. Installing a check valve helps maintain the efficiency of the pump and prevents unnecessary wear and tear. 

3. Pump controllers

Pump controllers are electronic devices that regulate the operation of your submersible pump. They can be programmed to start and stop the pump based on specific parameters, such as water levels or pressure thresholds. Advanced pump controllers also offer features like dry run protection, which prevents the pump from operating when there is no water, and overload protection, which shuts off the pump in case of electrical faults. These features help extend the life of your pump and ensure safe operation. 

4. Discharge hose and pipes

The discharge hose or pipe is a vital component of the submersible pump system. It transports the pumped water to its final destination, whether it's a drainage system, a garden, or a storage tank. Choosing the right discharge hose or pipe is crucial for optimal pump performance. It should be durable, flexible, and of the correct diameter to match the pump's output. Reinforced hoses are recommended for high-pressure applications, while corrugated hoses are ideal for more flexible setups. 

5. Strainers and filters

To protect your submersible pump from debris and sediment, strainers and filters are essential accessories. Strainers are placed at the pump's intake to prevent large particles from entering the pump, while filters are used to remove finer particles from the water. Regular maintenance and cleaning of these components are necessary to ensure the pump operates efficiently and to prevent clogging issues or damage.

6. Pressure tanks

Pressure tanks are used in conjunction with submersible pumps in water supply systems to maintain consistent water pressure. They store a reserve of pressurised water, which reduces the need for the pump to cycle on and off frequently. This not only extends the pump's lifespan but also provides a steady supply of water. Pressure tanks are particularly useful in residential and agricultural settings where a reliable water supply is critical.

7. Control boxes

For three-wire submersible pump systems, a control box is an essential accessory. The control box houses the starting components, including the capacitor and relay, which are necessary to start the pump motor. It also provides overload protection, which shuts off the pump in case of electrical issues. Ensuring that the control box is correctly installed and maintained is crucial for the safe and efficient operation of the pump.

8. Cable guards

Submersible pumps require electrical cables to operate, and these cables can be prone to damage, especially in deep well applications. Cable guards are protective devices that shield the cables from abrasion and other mechanical damage. They are typically made of durable materials like stainless steel or plastic and are installed along the length of the cable. Using cable guards helps prevent electrical faults and prolongs the lifespan of the pump. 

9. Pump lifting devices 

When installing or maintaining a submersible pump, having the right lifting equipment is essential. Pump lifting devices, such as slings or lifting eyes, are designed to safely and efficiently raise and lower the pump into position. These accessories ensure that the pump is handled correctly, reducing the risk of damage and making the installation process smoother and safer. 

10. Alarm systems

Alarm systems are crucial for monitoring the operation of submersible pumps, especially in critical applications like basement waterproofing or sewage systems. These systems alert you to potential issues, such as high water levels or pump failure, allowing you to take immediate action to prevent flooding or other damage. Alarms can be visual, audible, or connected to a remote monitoring system for added convenience.

Conclusion

Submersible pumps are invaluable tools, but their effectiveness and longevity can be significantly enhanced with the right accessories. From float switches and check valves to pump controllers, hose pumps, and pressure tanks, each accessory plays a crucial role in ensuring optimal performance and protecting your investment. By understanding and utilising these accessories, you can maximise the efficiency, safety, and durability of your submersible pump system.
