I am considering going from a 1.5 wf-26 to a 2 wf-28 would help me with the pros / cons Thank You

A     Answered on 6/27/2018 by InyoPools Product Specialist Hector F.

We would recommend staying with what the pool builder had placed on there as far as total horsepower, unless you plan on adding water features, moving the equipment further away from the pool or adding solar heating. If you do decide that you would like to go up in horsepower a wise choice would be by going with a replacement variable speed motor or complete pool pump. Maybe look into a Pureline Prime PL2606 pool pump.

how manny gph does a 2 hp pump make

A     Answered on 6/19/2018 by InyoPools Product Specialist Hector F.

The manufacturer provides a chart for calculating gallons per minute, so after calculating that based on your feet of head, you can then calculate the per hour rating. If you click here you can view the GPM chart for the Whisperflo series in the product details.

You will need two of these 2" Male Threaded x 2" Slip Unions the ports on this pump are 2" female and these unions will thread into the the female port.

What does full rate pump refer to verses this pump

A     Answered on 1/30/2017 by InyoPools Product Specialist Stacey M.

Hello Randy, From the specs of the 011774 that is a 1.5hp full rate, even though it says 2hp, because a 1.5hp single speed has the Total Horsepower of 2.25hp. So this is a full rate pump.

Does the Whisperflo 2HP pump include the 1.5 and 2 inch slip unions? Thankyou

A     Answered on 6/5/2016 by InyoPools Product Specialist Lennox H.

Hi Al, The Whisperflo pump does not come with unions, you will have to purchase them separately p/n 11201-0154. The unions can be used with 1-1/2" or 2" pipes.

Does this pump come with the motor also? I currently own this model but it's making lots of noise. Trying to decide if I want to attempt to rebuild the pump and replace the motor or buy a new unit.

A     Answered on 3/11/2016 by InyoPools Product Specialist Andy O.

Hello Shawn, The 011774 Whisperflo Pump 2 HP is a complete pump, which means it comes with the motor and strainer housing.

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.
