When shopping for a replacement spa pump, always ask for the original Megaflow™.
- The Megaflow™ is designed with a unique 8-vane impeller to dampen hydraulic noise.
- The Megaflow™ is designed to optimize spa pump performance while using the least electrical energy.
- The Megaflow™ pump passed all Public Safety tests per UL Standard 1081.
- The Megaflow™ 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.
- The Megaflow™ series has powered thousands of spas of different brands throughout the world since its introduction in 2005.
The Megaflow pump series will power your spa with the maximum pump efficiency and with the least hydraulic and vibrational noise. Our unique pump design with 2", 2.5" or 3" plumbing will put your spa performance ahead of your competition.
Our energy saver Model number MF523036 only draws 1.2 Amp on Low speed (276 Watt) and still pumps 59 gallons per minute to keep you electric spa heater cool. The cost of operation for our model MF523036 on Low speed is only $0.04 per hour (based on a U.S. national average electricity cost of $0.15 per kilowatt-hour).
Our pumps are ETL listed (U.S.), CSA listed (Canada) and CE (Europe) approved.
Please check our pump performance curves as well as the readings of the decibel meter while the Megaflow pump is performing in the open and at maximum load.
NOTES:
Pump Horsepower:
(cd) Horsepower is the continuous duty output power of the motor or the pump load to the motor.
(spl) Horsepower is used by the hot tub industry (for marketing reasons??).
(bd) Horspower is the motor's maximum load (exceeding this load will burn out the motor).
Model numbers with suffix (-1) indicates the motor is single speed.
Model numbers with no suffix indicate discharge straight up.
Model numbers with suffix (-3) indicates the discharge is to the right.
Model numbers with suffix (-4) indicates the discharge is to the left.
No O.E.M. dealers or distributor discounts with limited offer prices.
All pumps are not provided with unions, unions sold separately. Unions are identified by plumbing dimensions (like 1.5" or 2.0"),
but these numbers ARE NOT the physical outer pipe dimensions.
These numbers indicate the waterflow volume going into and out of the pump.
Please use part numbers as identified for your application.
All electrical work must be performed by a licensed electrician.
All plumbing work must meet I.A.P.M.O., UL 1563, and all local codes and regulations
and must be performed by a licensed plumbing contractor.
