i have the pentair wfds-4 ,, i understand repacement is B2982 , are their any other replacements besides the b2982? one other question do you carry the pentair just the motor WFDS-4 and not the PUMP thank you for your time

A  Answered on 4/12/2019 by InyoPools Product Specialist Lennox H.

Hi, Anthony. The B2982 or the SQS1102R motors can be used as an aftermarket replacement. We can special order the OEM WFDS-4 motor p/n 356630S.

When looking at this item, do I get both the pump and the motor for the same price or are they sold separately. I really only just need the motor. Thank you.


A  Answered on 3/26/2019 by InyoPools Product Specialist Lennox H.

Hi, Luis. This is the correct complete pump which will include the motor. You  can replace just the motor with P/N B2982 along with the Tune Up Kit GOKIT32 or GOKIT32SALT.

I need a run capacitor for this model

A  Answered on 1/24/2019 by InyoPools Product Specialist Lennox H.

Hi. We do not carry replacement capacitors for dual speed motors which we're working on getting. The part # is 195662-30 for your motor.

Pump no longer will operate in LOW speed. Works fine in HIGH speed. Any ideas on troubleshooting?

A  Answered on 7/31/2018 by InyoPools Product Specialist Lennox H.

Hi, Sean. I would recommend testing the Run Capacitor and or Pool Windings. Instructions are available in our How to Test a Pool Pump Capacitor Blog and How To Test a Pool Pump Motor Winding Resistance guide.

Does the pump come with union fittings? If not, what are the parts I need?

A  Answered on 11/4/2014 by InyoPools Product Specialist Andy O.

The Whisperflo Dual speed Fullrated 1HP pump (part number 011486) does not come with union fitttings. The part you would need part number 11201-0154. Thses unions are sold individually so you would need 2; one for the suction side and one for the discharge.

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.

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
