Need a Pump?

Types of Pumps

Pool pumps come in a wide variety of sizes to best match the unique needs of pools across the world. One way to classify pumps is based on the number of speeds at which it can operate. This is important because the speed of the pump has an incredible impact on the amount of energy it consumes - and, in turn, how much you pay on your electric bill. This is because of the Pump Affinity Law. This leads to three types of circulation pumps: single speed, two speed, and variable speed. As the name implies, a single speed pump operates at only one speed. These have been the standard type of pool pumps for decades, delivering proven performance and reliability. They are available in a range of designs and sizes (often in terms of horsepower) that match the wide variety of pool and plumbing configurations. Two speed pumps operate at either full speed or half speed - in other words, at 100% or 50%. These pump can offer up to 75% savings in pump energy costs and are also available in variety of designs and sizes.

For more information about variable speed pumps, click here Booster pumps are not needed for basic water circulation but rather deliver the added performance needed to operate pressure cleaners. They operate in conjunction with a circulation pump, boosting the pressure to assure consistent cleaner operation.

Energy Saving Variable-Speed Pumps

Variable Speed Pump Benefits

It may be surprising to learn that a single speed pool pump can be the second largest consumption of energy in your house after heating and air conditioning. With the installation of a variable speed pump, it is possible to cut the associated energy costs up to 90%, which can translate to hundreds or even thousands of dollars every year. As with most advanced, more efficient products, variable speed pumps cost more than single speed pumps. This incremental investment is often recovered in energy savings in less than two years. In addition, many municipalities and states offer utility rebates, further offsetting the initial cost. To calculate your potential savings, visit Hayward’s energy calculator.

Single-Speed and Two-Speed Pumps

Types of Single and Two Speed Pumps

Single Speed These pumps use an induction motor that runs at a constant speed of 3450 RPM. They can be flooded suction pumps, meaning they are placed below the water line using gravity to keep the pump primed, or they can be self-priming, which is the typical in-ground installation. Two Speed Pump The two-speed pump uses an induction motor that operates at either full-speed (3450 RPM) or half-speed (1725 RPM). When running at half-speed, a pump can provide significant energy savings, while still having the ability to run at full-speed when more water flow is needed.

Booster Pumps for Pressure Cleaners

What Does a Booster Pump Do?

A booster pump is used to power automatic pressure cleaners. The pump draws water from the pool circulation plumbing, increasing the water pressure so that the pool cleaner can operate at its maximum efficiency.
