Choosing the Right Submersible Utility and Dewatering Pump for Your Needs

Submersible utility and dewatering pumps, known for their versatility and durability, are a crucial component of many residential, commercial, and industrial applications. This comprehensive guide will help you make an informed decision when choosing the right pump for your specific needs.

Why Choose Submersible Utility and Dewatering Pumps?

These types of pumps are submerged directly into the liquid to be pumped, making them highly efficient as they don’t require much energy to move water into the pump. This position allows them to push rather than pull water, which makes them more effective than non-submersible pumps. They are also safe to operate as their submersion prevents pump cavitation, a problem that can potentially damage the pump.

Understanding Your Needs

Before choosing a pump, you need to determine your requirements. Here are some key points to consider:

  • Purpose: What’s the pump’s main function? Whether it’s for domestic dewatering, sump pit drainage, or industrial wastewater management, defining the purpose will guide your choice.
  • Volume: How much water needs to be moved? This will determine the pump’s required capacity.
  • Material: What is the liquid to be pumped? Is it clean water, dirty water, or sewage? The type of liquid determines the materials and technology the pump should have.

The Importance of Pump Size and Horsepower

A pump that is too small or lacks the necessary horsepower may underperform or fail prematurely. Consider these factors when choosing:

  1. Pump Size: The pump size should match the volume of water to be moved. Large volumes require larger pumps.
  2. Horsepower: More horsepower allows the pump to move water more quickly and over longer distances.

The Material of the Pump

Pump materials impact durability and longevity. Stainless steel and cast iron pumps are generally durable and resistant to corrosion, while thermoplastic pumps are lightweight and affordable.

Automatic vs. Manual Pumps

Automatic pumps feature a float switch that turns the pump on and off based on water levels. Manual pumps require manual operation, which might be a consideration based on your specific needs.

Pump Energy Efficiency

Look for pumps with high energy efficiency to save on operating costs. While these models might be more expensive initially, they can provide significant savings over the pump’s lifespan.

FAQs about Submersible Utility and Dewatering Pumps

1. How do I install a submersible utility and dewatering pump?

Though specific instructions depend on the pump model, most submersible pumps are installed in a sump pit or directly in the water source. It’s best to have a professional handle the installation to ensure it’s done correctly and safely.

2. What maintenance does a submersible pump need?

Regular inspection and cleaning can prolong the pump’s lifespan. Check for debris in the sump pit, inspect the power cord for damage, and test the pump regularly.

3. Can a submersible pump run dry?

No, running dry can cause severe damage to a submersible pump. Always ensure there’s enough water for the pump to operate.

4. How long can a submersible pump run continuously?

While many submersible pumps can operate continuously, it’s important to check the manufacturer’s guidelines to prevent overheating.


Choosing the right submersible utility and dewatering pump depends on a range of factors. By understanding these factors and consulting with water pump professionals, you can find the perfect pump for your needs.
