Consumer Comments:
"Hi Joe,
Pump arrived one day early. It took 20 minutes to get it wired and installed. It's a prefect replacement for the Aua-flo Circ-master HP and at considerable savings. This pumps runs very quiet. If I didn't have the water fall on I don't think I'd hear it. Will be in the spa shortly.
Regards, Ken Ekern"

When shopping for a replacement spa pump, always ask for the original Maverick.

  1. The Maverick is designed to optimize spa pump performance while using the least electrical energy.
  2. The Maverick pump passed all Public Safety tests per UL Standard 1081.
  3. The Maverick pump is powered by A.O.Smith/Magnetek/Emerson/Marathon Electric/Franklin Electric motors and not by inferior quality motors. Even though motor manufacturers may have different physical motor configurations (for example, capacitors and terminals in different locations), all motors are made per our pump performance specifications. Acura Spa pumps are produced and shipped per our model numbers with any of these motor brands.
  4. The Maverick series has powered hundreds of thousands of spas of different brands throughout the world since its introduction in 1988.

The Maverick pump series was first introduced to the portable spa market in 1988 as the first full-rated 2.0hp, 230V, 2-speed pump with a 48-frame motor. The Maverick was also the first pump with an eight-vein impeller design resulting in a dramatic decrease in operational noise while still maintaining high water flow. Throughout the years the Maverick pump has powered many spas made by: Action Spas, Carribean Spas, Catalina Spas, Curtis Spas, Dakota Spas, Diamante Spas, Dolphin Spas, Goodlife Spas, Grecian Spas, Hawkeye Spas, Hydromex, Islander Spas, Jetpool (Brazil), Leisure Spas, Life Spas, Lifespring Spas, Mountain Spring Spas, Orozco International Spas, Pacific Fiberglass, Pacific Pool and Spas (Canada), Platinum Spas, Seacard Pool and Spas, Sunbelt Spas, Sunquest Spas, Thermospas, US Tooling Spas, Vortex Whirlpool Systems, Inc., and many others. The Maverick pump can replace any spa pump with 1.5" intake and 1.5" discharge lines.
