9. Choosing A Pond Pump

Moving water is one of the most appealing aspects of pond keeping. Selecting the right pump for the job is an important step in having a successful pond. Most people add more and more features, such as filters, fountains and/or waterfalls, over time making adequate pumping an important issue. Choosing a pond pump is an important part of water gardening as it is the life blood of the pond, so this is not the place to cut costs. Pumps are under a heavy work load and must operate constantly and reliably 24 hours a day throughout the spring, summer and fall. Pumps that are too small for the job will clog more frequently, operate inefficiently, and eventually fail. A pump failure can be devastating to the animal life in the pond.

When choosing a pond pump, take into account the functions it will perform. Pumps vary widely in type, size, and purpose. Fountains or still, quiet, unfiltered pools benefit from water movement by small pumps to inhibit the growth of string algae and to break the surface for oxygen exchange. Larger pumps are required to power waterfalls, filters, and fountains, and it is important to select the best pump for the job. The choice can be made to power water features with an individual pump for each feature or a single, larger pump can be chosen to power all the features in a pond. Oase are good, reliable pumps and are available in sizes for every application.

Choosing a Pond Pump: External or Internal?

Two types of pumps are commonly used for water gardens: internal or external. Internal pumps are placed on the bottom of the pond and are connected from there to filters, waterfalls, and fountains. Internal pumps require protection from the debris that accumulates on the pond bottom. Placing the pump in a potting container filled with fibrous material to catch debris is a quick and inexpensive measure to extend the life of the pump. Some pumps can handle larger debris, but still will perform better over a longer period of time with some protection.

External pumps are situated outside the pond in some kind of protective housing and are connected from there to filters, waterfalls, and fountains. Like internal pumps, externals should be protected from debris entering the pump. An Aquarium Life Support Systems Intake Screen is an excellent pre-filter for larger internal and external pumps. Combinations of internal and external pumps for different functions are perfectly acceptable. Most pumps, whether internal or external, must not be run dry to avoid permanent damage to the motor. Oase and other pumps do have thermal shutoffs to protect them.

Factors to Consider When Selecting A Pump

Head Pressure

Head pressure, the manufacturer’s rating of flow at a given height or elevation and maximum pumping height, must be considered when deciding on a pump. Flow rate reported by manufacturers is the maximum, no-load flow rate for the pump. Filters, fountain heads, waterfalls, plumbing, and pipe and intake distance from the pond, combined with the maximum pumping elevation, determine a pump’s final output.

• Amperage or wattage – the lower the amps the lower the operating costs
• Maximum Cut Off or Shut Off-the highest elevation the pump can reach
• GPH gallons per hour of flow
• GPM gallons per minute of flow

Troubleshooting & Maintenance

A pump failure can be deadly to livestock. Periodic checks and following manufacturers’ maintenance recommendations helps prevent these disasters. Additionally, impellers do wear out. Many pumps have replaceable impellers or replaceable parts.

Plumbing Pumps with Other Watergarden Equipment

The diagrams below illustrate plumbing layouts for maximum performance of each feature.

It is always best to use larger plumbing to and from the pump than is required. Avoid 90-degree turns as much as possible, opting instead for sweeping spa hose (flexible PVC) or vinyl tubing. For very large water features, when both flow and energy efficiency are considerations, external pumps should be used. Dolphin makes superior external pumps for water garden use.

The diagrams above illustrate the filter and pump placement for high rate waterfalls and optimal pump configuration for maximum energy efficiency. Ponds powered by dual pumps assure redundancy and maximum efficiency. The pump not powering the filter can be turned off at night with a timer to save electricity. Increased oxygenation is assured during the day, when oxygen demands are greatest, with both pumps running.
