Product details

The Century BN34V1 is a two speed, up rated replacement pool pump motor: 1.5 HP, 230 volts, on a 48Y frame that the manufacturer also lists as Flex 48. It is a common swap for 48 frame pumps whose motor has failed while the wet end is still good.

What two speed buys you

High speed is for the jobs that need flow, vacuuming, backwashing and pushing water through a heater. Low speed handles ordinary filtration. Because power draw falls away sharply as speed drops, running the long filtration hours on low is where the savings live, and the pump is noticeably quieter doing it.

Before you order

Confirm three things: the supply is 230V, the frame is 48, and the horsepower and rating match what came off. This listing is the motor alone, so plan on a fresh shaft seal and any wet end gaskets at the same time.

Questions and answers

What people ask about this product, answered by our pool techs.

Will this run on 115 volts?
No. It is a 230V motor. Check the voltage at the equipment pad before ordering.
What does two speed give me?
A high speed for vacuuming, backwashing and heating, and a low speed for filtration. Running low speed for the long hours moves the same water using far less power.
Which pumps does it fit?
It is listed for Hayward® Power-Flo LX SP1580, 1520UN and 1680 series pumps, Pentair Dynamo pumps and Waterway Executive 48 frame pumps.
Is the part number BN34V1 or BN34SS?
The catalog lists this motor as BN34V1 and also references BN34SS. Match the number on your existing motor tag if you can, and ask us if the two do not agree.
