How do I know what size pump I need for my fountain?

Measure the diameter of the fountain spout with a tape measure. You will be calculating the gallons per hour, or GPH, by multiplying the diameter by 100. For example, if your fountain spout is 1 inch in diameter: 1 x 100 = 100 GPH, your pump will need to be rated at 100 GPH.

What size pump do I need for a tabletop fountain?

For example, a small tabletop fountain, such as the Water Bell Fountain, would only need a pump that pushed 50 to 100 gallons per hour. A wall fountain such as the Inspiration Falls fountain would need a larger pump, such as the WT 470, which pushes 370 gallons per hour.

What size pump should I get for my pond?

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.

What size Oase pump do I need?

The basic rule of thumb is that you need 100 GPH of flow for every 1 inch of width for your waterfall to achieve a “Sheet” look. Example: If you have an 8-inch wide waterfall and the waterfall is at a height of 5 feet, then you need a pump that delivers 800 GPH at 5 feet.

How do I choose a pump size?

Pump sizing involves matching the flow and pressure rating of a pump with the flowrate and pressure required for the process. The mass flowrate of the system is established on the process flow diagram by the mass balance.

What is the difference between a pond pump and a fountain pump?

I sell a line of cheaper submersible pumps at the garden center, and the only difference is that the fountain pumps have a two-prong plug and the ‘lamp’ type wire (flat), whereas the pond models have the three-prong plugs (grounded) and 16-3 round cord. This would mean we need a pump of approximately 3,000 gph.

What size pump do I need for a small waterfall?

Flow Rate: The average amount of water moving over a waterfall is 1,500 GPH for every 1′ of width. Therefore, a waterfall that is 2′ wide would need a 3,000 GPH pump. If you are looking for a heavier flow, calculate your flow using 2,000 GPH per foot.

How do I choose a pump?

Flow rate: Calculate your desired flow rate by multiplying the total volume by the time in which you want to move the liquid. For example, for a 500-gallon pond that needs full circulation once an hour, you would want to select a pump with a minimum rated flow rate of 500 GPH (gallon per hour).

How tall does a fountain pump need to be?

If you want a trickle of water to gently fall from the spout, you will need a pump that measures at just about the same vertical measurement as the head height rating. For a strong flow of water from the spout, choose a pump with a maximum height that is higher than that of where the water emerges.

What does GPH stand for on a fountain pump?

Keep this in mind when selecting a replacement for your water fountain or pond. You will see the abbreviations GPH when looking at the specs; this stands for “gallons per hour”. This measurement is what determines the flow rate of your fountain.

Can a WT pump be used on an outdoor water fountain?

Below you will see some general guidelines on how to select a pump for your indoor or outdoor water fountain. Pumps with a WT model number can be used on indoor or outdoor fountains. This means they have a three-pin plug. The WP pumps and Mini Jet Pumps are rated for indoor use only—only a two-pin plug.

How is the height of a water pump determined?

This measurement determines the maximum head height rating, which is how high the pump will need to lift or push the water to reach the fountain head. This measurement is different from the “pumping height” which is the measurement from the outlet port on the pump to the top of the water.

How much water does a fountain pump take?

The rule of thumb, depending on just how much water you want coming out of the fountain, is 100 GPH per one inch diameter of fountain outlet.
