Everything You Need to Know About Choosing a Submersible Well Pump

When you need to pump water from a source to a plumbing system, it is important to have the right equipment available. Pumps come in a range of speeds and power levels for moving the water from a deep well to above-grade soil and into a building for use. On eBay, you can find a variety of pump sizes and capacities and in various condition states at affordable prices.

What are some of the features of an underwater pump?

The available features of these liquid pumping devices are described here:

  • Stainless-steel construction: The stainless steel resists rust and corrosion, which is important in wells that contain a lot of corrosive or hard minerals such as iron.
  • Thermal protection: The insulation protects the pump from freezing if the temperature drops below 32 degrees Fahrenheit.
  • Built-in check valve: This stops the pump from causing backflow or pumping liquid when the primary valve is closed.
  • Range of settings: These pumps are designed for drawing liquid from a reservoir, well, river, or lake in civil and residential settings.
What are the pumping capacities for these submersible pumping systems?

The pumping pressure of these submerged pumps ranges from 10 to 400 pounds per square inch (PSI). The deeper the pump is submerged into a well, the greater the pressure the motor is under. The speed of the pumps ranges from 4 gallons per minute to 42 gallons per minute. The rated speed will vary based on the amount of PSI the pump is under.

What are the available types of submersible water pumping systems?

The available types of well-water pumps on eBay include the following:

  • Deep well: The pumps may work in wells up to 400 feet deep.
  • Sump well: These wells are up to 20 feet deep.
  • Combination: Some of the pumps are designed for shallow sump wells or use in a deep water well.
