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??).

Model numbers with suffix (-1) indicates the motor is single speed.

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.
