I just bought the LA01N Universal booster pump and had it installed. It stated that the motor is premiered for 230 high voltage and needed to be modified by a certified electrician to low voltage. Did that but when we ran it it started smoking. What could be the problem.
Robert, If the motor started smoking, it may have been wired incorrectly. Please check the wiring diagram on the motor label and compare it to how the wires are connected to the wiring terminal.
MY 10 year old Pentair LAO1N single speen pressure side pool cleaner (legend platinum pool clener) booster pump, 3/4 HP, 115/230 volt just burnt up and I need to replace.
Shouls I consider upgrading to the Pentair LA-MS05 Boost-Rite ?
Please suggest a replacement booster pump for my Pentair Platinum Legend. The current pump nameplate show part no. 7-187400-20; is 3450 rpm; 3/4 HP; 240/110v. I don't have the capacity nor discharge pressure.
My booster pump just hums and won't start, it will stay like that and will become hot. The shaft will spin if I turn it with my hand. What do you suggest to check/replace?
Hello David, I would recommend someone to come out and check the unit, how long have you had your unit?
How do I check to see if the start capacitor on top of the motor is bad. I opened the cover and everything looks OK, (not burnt). Motor trips when turned on. You can here it hum for a couple of seconds without turning the motor shaft, then trips. I have a multi-meter, but not sure how to test the start capacitor.
If all it's doing is humming than it's the capacitor that needs to be replaced.
How can the pump motor be disconnected from the flange for repair?

can I use this pump to run my pool polaris
This pump works with the following Letro Pool Cleaners,Letro Legend, Letro Legend Platinum, Letro Jet Vac Cleaner, Letro Pool Sweep Letro Pool Sweep II Only. Polaris 3/4 HP Booster Pump PART#PB460 will be needed
The motor worked perfect yesterday. Today it hums for about 5 seconds and the rotor does not turn over, then it stops humming. sn 1-21-h08 What is the round box on top of the motor?
The round box on top of the motor is a start capacitor. If the motor hums and then trips, more than likely that capacitor has gone bad. To get the correct one, we would need the numbers off of the specific capacitor inside that cover.
I started getting my pool ready for the pool season when i turned on the pump i noticed the booster pump leaking from the center. What parts should I replace?
Hi Joseph, If you have a Letro or Pentair LA01N Booster Pump then we would suggest replacing the Letro Booster Pump Shaft Seal and the Letro Booster Pump Body O-Ring. We also carry All of the Replacement Parts for the Letro LA01N Booster Pump.
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.
What is a booster pump, and where does it attach to?
This cleaner is designated as a pressure side cleaner which means:Pressure Pool Cleaners most pressure cleaners require a booster pump which is typically a ¾ horse power pump that is dedicated for use with the cleaner alone. The booster pump allows you to operate the pressure cleaner without taking any suction away from your main pool pump. The addition of the booster pump does mean pressure cleaners require a more involved installation than either suction or robotic cleaners. The booster pump is installed in tandem with your pool pump.

(4 out of 5 stars) Pool sweep pump
Reviewed By: LKJU from Hurst, TX ()
Pros: Haven't changed design.
Cons: Lasts only five years.
This is the exact same pump that was installed when my pool was put in, so installation is pretty easy. I just put it in same as the old one. I only wish they would last more than 5 years. It runs only about 3-4 hours a day, and I literally have replaced it every five years. This was my third pump in 11 years.
