How does the dual speed feature of this pump work?

A  Answered on 6/15/2006 by InyoPools Product Specialist Patrick P.

Some dual speed pumps have a toggle switch in the back of the motor to change speeds manually, but many do not. Generally you would need to tie this dual speed pump into one of our dual speed pump timers/controllers. One of the more popular models is the Digital PE153 series. This timer has 3 functions: one to turn the pump on and off, a second auxiliary to switch from high speed to low speed, and then a third for any other piece of pool equipment. You may view these controllers through the following link: Intermatic Timers

I just finished replacing the shaft seal on my booster pump. As soon as I turned the pump on water was leaking from the shaft seal. Is it defective or am I doing something wrong?

A  Answered on 2/16/2012 by InyoPools Product Specialist Patrick P.

Depending on the model, the installation of a booster pump shaft seal can be slightly different than a pool pump shaft seal. Some booster pump and pool pump shaft seals require that a silicone sealant be used on the outer areas of the metal seat of the shaft seal. The seal will need to be lightly hammered into the body of the pump. You can use a 1 inch PVC coupling or a piece of 1 1/4 inch PVC pipe and a rubber mallet. This procedure will apply to any pool pump or booster pump using a >PS-1000 style shaft seal.

What is the difference between the Wisperflo 011523 and the Wisperflo 011524. The 523 is much more money. They are both dual speed, 2hp, and 2in inlet and outlet. Looks the same.

A  Answered on 11/26/2018 by InyoPools Product Specialist Hector F.

The model 011523 is actually a full rated which means that the total horsepower is more by about .5.

Replace with Dual Speed for Energy Savings

Written on 3/6/2019 by Guest

The first step for a project of this magnitude is plan the install. Deciding how you rerun the pipe, if you need to redo any wiring, how you are going to control the dual speed (SPDT switch, new timer, automation controller), and making a list of everything extra you will need (wire conduit, wire, fittings, electrical quick disconnects, etc).

For my install I was replacing a single speed Pentair WhisperFlo with a Dual Speed model. So, all my suction and discharge piping lined up. Electrically, my setup uses an Intermatic T104M201 for the main pump. So, to keep it simple I ran the pump off the existing T104M201 timer and have a SPDT switch in the breaker box for the high and low speed.

1) Turn off the breaker from the main breaker box that feeds your pool equipment (you should also check with a multimeter to verify the power is off at your pool breaker box).

2) Remove the old pool pump (I had to use a hacksaw on the suction side pipe).

3) Remove old wiring conduit (mine was deteriorated and needed to be replaced).

4) Using a new liquid tight wiring conduit, run 4 wires to the motor (check your local code for wire gauge and color). I also used a metal 90 degree liquid tight fitting on the pump side.

5) Run the new liquid tight conduit/wire to your breaker box and hook up to your control method (ie) Timer, SPDT or DPDT Switch, automation controller, etc.

6) Thread in a 2" high temp union to the inlet and outlet of the pump.

7) Check your piping lengths and cement in the new slip unions so they line up properly with the inlet and outlet ports of your pump (you may need new SCH40 PVC piping, unions, elbows, etc).

8) Give the cement time to dry (read the instructions of the cement used).

9) Fill the pump basket with a bucket of water and then close the lid.

10) Turn back on the breaker for the pool equipment.

11) Turn the power on to the pump and monitor the water flow to make sure the pump primes (use your pool filter air relief to purge air from the system). Also check your dual speed modes to make sure both work.

Congratulations, you have DIY’d your pool pump and saved a lot of money in the process!
