NOTE 2: The 1.0HP motors are only available in 110V, and the 1.5HP motors are available in either 110V or 220V. Motors larger than 1.5 HP must be 220V.

NOTE 3: Amp rating and dimensions may vary depending on the motor brand and model that is used with this pump. Motor brand can be US Motors, AO Smith Century Laser, GE, Etc... Please contact us to verify dimensions if space is very limited for the new pump.

Pumps with 48-frame motors can be ordered with "SIDE" or "CENTER" discharge. Center-Discharge pumps come standard with 1.5 inch fittings (outside thread measurement are approximately 2-3/8 inch). Adapters are optional for the center discharge pumps when 2.0 inch fittings are requested. Side-Discharge pumps come standard with 2.0 inch fittings (outside thread measurement are approximately 3.1 inch).

Diagrams below shows both pump discharge on top pointing to the 12 o'clock position. The pump discharge can also be rotated every 90-degrees (3, 6 or 9 o'clock positions) by loosing the four long bolts at the back of the motor. The pump intake (suction) is located in the front center face of the pump.

If buying this pump for retrofitting, add a pair of pump unions that connects to your pipes which then screws directly onto the pump threaded fittings. O-rings are included with the pump unions. Regular price is $22.95.

If buying this pump as an exact replacement that does not require retrofitting, it is highly recommended to replace the pump union o-rings at the same time. Old pump union o-rings may cause leaks that can damage the new pump and affect the warranty. O-rings for pump unions are only available with a pump union purchase.

You may add a cord to be attached to the motor at a discounted price. See cord options below.

The pump normally ships from the factory with the discharge pointing "UP" which is the standard position for shipping, but they can be turned or what is called "clocked" into any position (12, 3, 9 or 6 o'clock position). Rotation of the pump discharge can be done in the field, but we recommend having it performed by a professional spa technician who is experienced. Or choose the option to have the pump professionally rotated at the factory before it ships. This is to avoid water leaks and operational problems due to improper removal and installation in the field that will affect the warranty. As you face the front end of the pump wet end, available positions are 12 o'clock (Up), 3 o'clock (Right), 9 o'clock (Left), and 6 o'clock (Down, which is very rare).

Pumps with 48-frame motors carry a 1-Year Limited Warranty. (Starting 12/06/2017)

Keep in mind that if your pump is rated 56-frame, you might want to consider the 56-frame Pump

Is Your Pump Above the Water Line?

If you need to install your spa pump near or above the waterline - as is common for in-ground spas - you will need a pump pot. The pump pot help prevents water from draining back into the spa when the motor is turned off
