How To Choose The Best Pond Water Pump?

When you’re planning to build a pond one of the first things that you need to think about is the pond water pump. The decision will depend on the size of the pond, flow rate required and efficiency of the water pump.

Tip 1: The minimum flow rate should be 1/2 of your pond volume. Sometimes even this is not enough.

Tip 2: If you have a waterfall in your pond, you’ll need to increase the size of your pump.

Which type of pond water pump is best?

This depends on the design, size and purpose of your pond.

  1. how long the pump will last
  2. how often it needs to be cleaned
  3. how clean or dirty is the water where the pump will be working

External Pumps

The 4 pros for external pumps

  1. external pumps tend to be more energy efficient
  2. they last a lot longer than submersibles
  3. they cost less to operate over a long period of time
  4. the parts are cheaper to buy than submerged pumps.

For these reasons when choosing a product it’s advised to go with an external pond pump, if possible.

You might find that decision saves you a lot of time and money.

Submersible Pumps

Submersible pumps are made for small to medium sized ponds with roughly 200 – 800 gallons of water. These connect easily to most of the submersible filters built for small to medium sized ponds.

The pros of submersible pumps

  • they’re relatively cheap to buy
  • they are much easier to install than external pumps

The disadvantages

  • submersible pond pumps often cost a little more to operate
  • you’ll have to replace them more often than you do an external pond water pump
  • parts for submerged pumps can be more expensive

Submersible pumps will tend to have a shorter life than external pumps. Most of them will last for a little over a year because they are sitting in the middle of the pond and are absorbing dirt and pond filth all of the time. This eventually causes wear on the pond pump and causes it to have a shorter life than an external pond pump.

Solar Submersible Pumps

There are also solar submersible pumps. These pumps require a lot of sunshine, therefore an option only if you live in an area that gets a lot of sunshine.

Submersible pumps come in 12 or 24 volts. The size of your pond will determine how many volts your pump needs.
