What You Need to Know When Buying a Submersible Pump

A submersible pump is an effective piece of equipment to reduce your dependence on mains water. This robust piece of equipment is easy to use and maintain. But just like other types of plumbing equipment, you need to do a bit of research to find the one that suits your needs.

Pumps2You carries everything, from Lowara to Davey pumps here in Australia. Choosing the right pump will require figuring out the specifications of your site and how the pump will be applied. Taking your time to browse through and choosing the right pump will prevent costly replacements and repairs in the long-term.

How to Choose a Submersible Pump

Submersible pumps are straight to the point in their design. But what it lacks in aesthetics, it makes up for in functionality. Identifying the specifications for these will guide you in your selection process.


Submersible tanks are largely designed to suit the viscosity of the liquid it is submerged in. Determine the primary purpose of your pump to narrow down your search.

  • Look towards a clean water submersible pump for rainwater harvesting. This model has narrow filters which will prevent unwanted particles from entering your water supply.
  • For floodwater management, consider a wastewater model. Its filtering device ensures suspended solids are kept from contaminating the pumped water.
  • There are heavy-duty pumps available for heavy wastewater. These models are often equipped with a shredder to break down large pieces of debris.


Determine the water flow you need. Since submersible pumps are largely reliant on kinetic energy, the flow plays an important role in how it operates.


Water pressure is dependent on the type of pump you want. A lifting pump has no need for it, while a feed pump needs it to function. Use a tyre gauge to measure your supply's water pressure.

Discharge Height

The discharge height determines how well your submersible pump operates. This is where it will get the pressure it needs to move water. Your water flow will significantly decrease with a higher discharge height. If you want stronger water pressure, look for a submersible pump with a low discharge height.

Other Considerations to Keep in Mind

Once you've determined the type of pump you need, there are other factors to consider. Although these are supplementary, they still play an important role in ensuring the effectiveness of your pump.

Identify the Right Float Switch

Your float switch is largely dependent on the size of your pump. Used to control the pump, you need to make sure the one you choose can handle the expected water pressure and flow.

  • A vertical switch pump moves in an up-and-down motion. This type of float switch is commonly used for deep wells and boreholes
  • A tethered switch pump moves water in a diagonal direction towards the surface. Its wide-angle allows you to get the most out of your watering system.

Choose an Effective Backup System

If you are using your submersible pump to mitigate flooding, you must have a backup power source. Your pump will need a jumpstart in the event of a blackout.
