Motor on WF-28 burned out after 4 years in service. What can I use to replace the 2hp 3350014S? Is there a suggested Pentair replacement (355026S etc.)?
Here is a link to the Pentair 355026S Replacement Motor you can also use a PureLine PL2859 HP Motor which is considerably less $$ and is the same motor with the exception of the color. You will also need a Pentair Whisper Flo Seal Kit when you replace your motor. We put together this Video on How to Replace a Pool Pump Motor which you may find helpful when you tackle this project.
My pool guy replaced one pool pump with a Pentair SuperFlo 1.5HP but he had quoted me a Pentair WhisperFlo 2HP. He said that the SuperFlo was a better unit. Is this true? Every place that I look the SuperFlo is less expensive, but he is trying to charge me more.
Hi, Bob. The SuperFlo Pump is not a better pump than the Whisperflo Pump. The Whisperflo Pump is a higher performing pump than the Superflo pump.
Is there a wf-28 equivalent Penrair pump that comes without the motor? I just replaced my motor and when I turned it on the older pump is now leaking so I want to purchase and replace the pump only.
I have a WF 28 and it is about 10 years old.
I had to replace the motor once already, about 5-6 years ago and now that replacement is quite loud. It is still running though.
Should I replace just the motor again, or should I consider replacing the whole pump?
I am considering going from a 1.5 wf-26 to a
2 wf-28 would help me with the pros / cons
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
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.
What type of fitting is required and what is the thread style on a Pentair Whisperflo Model WFE-28 2 HP pump inlet pipe?
What does full rate pump refer to verses this pump
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
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.
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?
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.
(5 out of 5 stars) Great product, shipping not so
Reviewed By: JOHN B. from Dallas, TX ()
Pros: Quiet operation, ships in one piece, previous pump/motor lasted 16 years. I got what I ordered.
Cons: Damage from shipping. No con's for the actual product.
This replaces an identical WhisperFlo which finally gave out after 16 years. The new one is working well but I was concerned I may have to file a claim after noticing damage from shipping. The plate at the back of the motor (away from the pump) was broken off as well as the pedestal. The box was well-padded on top but the shipment from Florida to Texas did not holdup very well on the bottom. Fortunately, the damage seems to be only on the motor end. The pump shows no damage. The pump is up and running quietly.
