Best Pond Pump Information 2021

Pumps keep the water in your pond healthy. They help evenly spread nutrients in the water to fish, plants and other aquatic life. Running water prevents stagnation and cuts down on algae and mosquitoes. Keeping the water moving ensures that oxygen levels are distributed throughout the pond. Pumps also provide power for a pond’s water features, like waterfalls and fountains.

This guide will help you learn about the best pond pumps for your garden.

The best water pumps for your pond and its fountain or waterfall come in variety of types and styles. They include submersible, external, magnetic drive and direct drive. Each of these water garden pumps offers its own advantages.

Submersible Pumps: These pumps are designed to work while wholly submerged in water. Typically, they are installed in the deepest part of the pond. Submersible pumps can be placed either directly into your pond or in a skimmer box or pond vault.

  • Easy to install.
  • Work well in environments that capitalize on a natural setting.
  • No need to camouflage the pump.
  • Run very quietly so there’s no distracting noise in your garden.
  • Submersible pumps can be used to drain your pond, if needed.
  • Range in pumping size from 50 to 5,000 gallons per hour.
  • Can generate higher energy costs than other pump types.
  • For smaller ponds, submersible pumps are generally more economical.

Tip: Some submersible pumps use oil to operate. If the pump seal breaks and leaks harmful oil coolant into the water, fish can be hurt or killed. If you have fish or other aquatic life in your pond, you’ll want to look for a submersible model that does not use oil.

External Pumps: External pumps can move a high volume of water, yet usually have lower energy costs than submersible pumps. They are not as quiet as submersible pumps. They should be placed in a dry location near your pond. External pumps are a lot more complicated to install. However, they are generally more reliable.

  • Available as self-priming pumps able to draw their own water.
  • Can be loud, disturbing the quiet of your garden.
  • Work well for larger ponds that are 1,000 gallons or more.
  • Offer long-lasting performance and easy repair.
  • Require less routine maintenance than submersible pumps.

Tip: Pumps that are not self-priming can burn out a motor if the power shuts off momentarily and then comes back on. Protect against this by installing a check valve.

Magnetic Drive: In a magnetic-drive pump, an electrical charge creates a magnetic field that causes the magnet on the impeller to rotate and pump water. Since they have no seals to wear out, they require little maintenance. Occasionally, you will need to clean the impeller and its chamber for the most efficient operation.

  • Completely sealed. Magnetic-drive pumps do not require lubrication.
  • Because they don’t contain oil, magnetic-drive pumps are safer for ponds with fish, since oil leaks don’t occur.
  • Don’t generate high head heights. Magnetic-drive pumps are unable to lift pond water vertically, which you might need to supply water to a fountain. They are not the best water pumps for fountains.
  • Work best in cleaner environments with little or no debris.
  • Highly efficient and cost-effective.

Direct Drive: Direct-drive pumps have an enclosed motor that is powered by electricity, which turns the impeller shaft.

  • Achieve significant head height, so they are able to move water vertically. They are among the best water pumps for fountains and waterfalls.
  • Typically more expensive to operate.
  • Push water rather than pulling it.
  • Not easily repaired.

Tip: Some models seal the motor in an oil-filled shell with seals around the cord and impeller shaft. These are risky to use if you have a pond stocked with fish. There is an ever-present danger of water contamination if a leak occurs. Many newer pumps, however, feature alternative lubrication that is safe for fish. Look for oil-free models if you have fish or other aquatic life in your pond.

Pond Pump Calculations

Figuring out the correct pump size depends upon the how big your pond is. Other factors include whether or not the pump is being used for filtration, re-circulation or water features. Another factor is the number of fish and plants your pond contains. Larger fish populations have greater air requirements.

A good rule of thumb is that pumps should be able to pump out about half the pond volume every hour. For example, a pump that moves 500 gallons per hour would be appropriate for a 1,000 gallon pond.

You don’t have to refer to a fountain pump size chart to figure out the best water pumps for your garden. With a few measurements and calculations, you can determine the size pump you’ll need.

Flow rate for filtration

  • Filtration flow rate in gallons per hour (gph) = 0.5 x pond volume (gallons)

Flow rate for fountains

  • For every inch of stream width at the top of the fountain, you need 100 gph at the height you’re pumping

Flow rate for waterfalls

  • Light flow = 50 gph x waterfall width (in.)
  • Average flow = 100 gph x waterfall width (in.)
  • Strong flow = 200 gph x waterfalls width (in.)

Pond volume

  • Pond volume (gallons) = 7.5 x average width (ft.) x average length (ft.) x average depth (ft.)

Pond Pump Features

In-line, utility, solids and axial pumps are just a few of the many varieties of water garden pumps that are available.

  • In-line Pumps: These pumps draw water through an inlet that connects to a hose so you can pull water from a remote location. All external pumps are in-line pumps.
  • Utility Pumps: Utility pumps draw water through openings that screen out debris. When placing one into a pond, use a pump sock or other enclosure to reduce the amount of cleaning needed. If you use a pump sock, be aware that sock-like screening can cause a dry pump situation.
  • Solids Pumps: These pumps draw water through a large opening and pump small debris through without clogging. For this reason, they can be placed into a pond without prefilters. This pump type is not safe for ponds with fish, frogs or other aquatic animals, however.
  • Axial Pumps: These special utility pumps are designed for high-flow, low-pressure pond environments. Because they are big, they require piping that is large in diameter.
  • Solar Pumps: Solar-powered pumps perform well in climates with lots of sunshine. They can cost less to operate since they don’t require an outdoor electrical outlet. Solar pumps also work well if your fountain is located far from the power supply. However, flow rate is minimal compared to typical voltage.
  • Heavy-Duty Pumps: Heavy-duty pumps are typically made of stainless steel and are more costly. However, they offer greater energy efficiency and last longer.

You’ll need to consider several factors when deciding between the best water pumps for your garden pond. A pump should be able to handle the size of your pond and support your water features. It also needs to be compatible with any fish or plants you may have.

Pond Management – Spring Start Up of Your Aerators

 

If you turned your aerator off and stored it for the winter they are a few quick steps you can take to have your aeration system prepped and installed for the spring. If your winter has been anything like ours, spring already seems upon us.

Here’s 4 ways to prep and install your aeration system for spring.

1.)  Change the air filter: The air filter is vital for providing clean air through the compressor. With a clogged air filter, performance diminishes and over time can cause irreversible damage to the compressor. We recommend changing your air filter every 3-6 months depending on the environment.

2.)  Check for Air: Before installing the unit and connecting airlines it is best to do a quick check for air. Turn the unit on and ensure air is coming out of the flex hose(s). If you have a multiple diffuser plate system, make sure that the valves are not completely shut off. In the event where air is not coming from the flex hoses, you may need a maintenance kit to replace the diaphragm.  Call 877 780-1174 for more information and pricing on replacement parts.  Some newer diffusers are self cleaning.

3.)  Reinstall the unit: To reinstall the unit, you’ll want to re-position the cabinet so it is sitting level, reconnect the airlines and plug it in. Adjust the airflow as needed, which you’ll need to do anyway if you have multiple diffuse plates. Adjust the flow so each air plate receives equal amounts of airflow and keep in mind that longer runs and deeper plates will require more airflow to operate than shallow plates and shorter lines. It usually takes a few minutes between adjustments to see the effect at the diffuser plant, so be patient!

4.)  Proper start up: Introduce your aeration system slowly in the beginning, and gradually increase its running time each day. Start by running it for an hour the first day, two hours the second day, doubling the amount of time each day until you can successfully run it for 24 hours. If you run the system immediately for 24 hours upon returning it to the pond, you could cause the warm and cold layers of water to mix too quickly which may harm fish.

These quick steps will ensure your aeration system is back up and running to keep your pond clean, clear and healthy for years to come.

Planning: Pond Calculations

Here’s the rule of thumb for measurement of your pond.

SQUARE FEET on the surface area.

  • Rectangle

length x width = Square feet of pond

  • Circular

3.14 (1/2 diameter x 1/2 diameter) = square feet of surface

NUMBER OF CUBIC FEET

  • Rectangle

average length x average width x average depth = volume in cubic feet

  • Circular

3.14 (1/2 diameter x 1/2 diameter x depth = volume in cubic feet

To calculate GALLONS in your pond

cubic feet x 7.48 = capacity in gallons

FORMULAS TO DETERMINE APPROXIMATE AMOUNT OF ROCK NEEDED:

  • Quantity of BOULDERS in a pond (tons) = length (ft) x width (ft) divided by 65
  • Quantity of BOULDERS using 1.2.1 ratio. Length x Width divided by 40
  • Quantity of 1/4 inch to 3 inch GRAVEL (tons) = tons of boulders x .45
  • Quantity of BOULDERS in a STREAM = 3/4 TON PER 10 FEET OF STREAM LENGTH

Around the FACE of A SIGNATURE 6000 BIOFALLS you will need approximate 3/4 TO 1 1/4 tons of boulders.

Note: If you are building a large water feature you will need to increase the tonage of rock as the stone you will use will be larger and carry more weight.
