Is there a variable speed alternative for this? Currently have the LA01N with Pentair 7-187400-20 Thanks, Gene

A  Answered on 10/26/2020 by InyoPools Product Specialist Hector F.

Hi Eugene, unfortunately not for this version motor. These are more of a special application type of a motor for a pool cleaner booster pump.

How quickly could this ship, and arrive in Michigan? I could pay extra for overnight service, if I knew the cost.

A  Answered on 6/9/2020 by InyoPools Product Specialist Patrick P.

Hi Leonard, It does look like we do have this in stock in our Michigan warehouse and if you ordered right not then most likely it will ship tomorrow for delivery on Thursday or Friday. This would be Free Shipping. The next day air would still ship out tomorrow and would be over $100 in shipping. If you place the order please reply back to this thread so we can make sure the order gets routed to our Michigan warehouse. Unfortunately this is not available for pick up and would have to ship out.

My pump motor is missing the plastic shaft end cover located near the electrical cover. Are these sold separately?

A  Answered on 4/13/2020 by InyoPools Product Specialist Megan C.

Some of these are sold separately. We will need the model, part or catalog number of the motor to confirm or if you cannot locate that please send us a few images of the motor at upload@inyopools.com.

Currently I have a Pentair LA01N pump on my pool and need to replace it. Do i have to replace it with that pump or can I use Zodiac PB4-60 Polaris Booster Pump with 60-Hertz Motor? Thx

A  Answered on 9/23/2019 by InyoPools Product Specialist Lennox H.

Hi, Charles. It will be best to replace it with the LA01N model.

Is this booster pump salt water capable?

A  Answered on 6/1/2019 by InyoPools Product Specialist Hector F.

These do not come saltwater friendly from the factory as most pumps in the industry come, but you can always change the main shaft seal to a heavy duty version and make the pump salt friendly. That shaft seal would be part number 5250-225.

Will this booster pump work for my polaris 3900 sport. My current motor specs are Part: 7-173840-23, Serial: 115113m, FR: N56CZ, Type: CS, HP: 3/4, SF 1.50, HZ: 60, Amps SF: 6.4/12.8, RPM 3450. Thanks

A  Answered on 9/15/2018 by InyoPools Product Specialist Lennox H.

Hi. This Letro Universal 3/4 HP Booster Pump - LA01N can be used; however, I would recommend the Polaris 3/4 HP Booster Pump - PB460 which will be the direct replacement for what you have. 

?     Asked on 5/16/2018 by Robert

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.

A  Answered on 5/17/2018 by InyoPools Product Specialist Alex V.

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.

A  Answered on 9/8/2017 by InyoPools Product Specialist Lennox H.

Hi, Pat. You can replace the LA01N pump with the Boost-RitE® Booster Pump - BOOST-RITE. It's a more efficient pump.

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. Thanks.

A  Answered on 6/25/2017 by InyoPools Product Specialist Hector F.

The replacement complete pump for your cleaner is the LA01N. I would also inspect all hose connections and flow rates in your system to make sure there are no issues besides the booster pump.

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?

A  Answered on 8/16/2016 by InyoPools Product Specialist Stacey M.

Hello David, I would recommend someone to come out and check the unit, how long have you had your unit?

?     Asked on 6/24/2016 by

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.

A  Answered on 6/24/2016 by InyoPools Product Specialist Scott W.

If all it's doing is humming than it's the capacitor that needs to be replaced.

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?

A  Answered on 6/19/2015 by InyoPools Product Specialist Brian M.

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.

Can this be used with Polaris poolside cleaner?

A  Answered on 4/6/2015 by InyoPools Product Specialist Robert M.

Hello Jim - The Letro Universal Booster Pump can be used with the Polaris cleaners.

?     Asked on 2/16/2012 by Guest

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 a booster pump, and where does it attach to?

A  Answered on 4/12/2009 by InyoPools Product Specialist Patrick P.

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.

Is the hose kit (353020) included with this?

A  Answered on 3/2/2008 by InyoPools Product Specialist Patrick P.

Yes the hose kit does come with this booster pump.
