  1. The Magnaflow is designed with a unique 8-vane impeller to dampen hydraulic noise.
  2. The Magnaflow is designed to optimize spa pump performance while using the least electrical energy.
  3. The Magnaflow pump passed all Public Safety tests per UL Standard 1081.
  4. The Magnaflow pump is powered by A.O.Smith, Magnetek, Emerson, Marathon Electric, Franklin Electric, SNTech, Regal Beloit or Century 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.
  5. The Magnaflow series has powered hundreds of thousands of spas of different brands throughout the world since its introduction in 1994.

 

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.
