How do you size a pump motor?

The power required to drive the pump at the rated design condition should always be less than the nameplate horsepower rating of the motor. So if the pump will require 4.5 HP at the design condition, at a minimum, the motor should be sized for 5 HP – the next nominal size above 4.5 HP.

How do I choose a motor and pump?

When choosing a motor for a centrifugal pump, you must consider the impeller size, maximum capacity, specific gravity of the fluid, and service application in case API requirements apply. If you take these things into account, you will select the right motor for your centrifugal pump application.

How do I choose a water pump for my motor?

How do you specify the drive motor for a well pump?

Motors are usually specified by their power output, not input, so don’t use this number to specify the drive motor necessary to drive the pump. For pumps in wells the depth to the free water surface in the well while pumping needs to be added to the pressure required at the surface.

How much GPH do I need for a moderate flow pump?

To create a moderate flow, look for a pump that supplies a flow rate of 150 GPH for every inch of width. To make the flow gentler, adjust this figure to 100 GPH; to make it more powerful, adjust to 200 GPH per inch. For example]

What size waterfall pump do I need for my Pool?

For example, if your fountain’s head height is 22 inches and its outlet diameter is 3 inches, you’ll want a pump that provides least 300 GPH (3 * 100 = 300 GPH) and has a max head height of about 33 to 35 inches (22 * 1.5 = 33). To obtain the optimal waterfall flow, you need to consider both spillway width and vertical height of the feature.

How much water does a pond pump need to circulate?

If your pond is densely stocked, your pump should circulate the entire volume of water every hour. That means that if your pond is 1,200 gallons, your pump should supply a flow rate of 1,200 GPH at the head height of the outlet.
