I am in need of a replacement pool pump and have a question about the Magnum Force Pump 1 HP Pump. Does this product come with salt water pool seals? If not, do you have a link or part number so I can purchase them? Many thanks!

A     Answered on 7/22/2018 by InyoPools Product Specialist Lennox H.

Hi, Michael. This pump comes with an OEM seal which can be used with salt water too. Here is the link to the Saltwater Pump Shaft Seal - PS-3868

Hi, Ryan B. Replacing the Magnum Force Pump 3/4 HP - 7UMF-S with this Magnum Force Pump 1 HP Pump - 1UMF-S will move more water, however, you will have to determine if your filtration system is sufficient.

I am looking to replace a Jacuzzi Magnum Force in ground pump, Model 7MF-S. The motor says 1 H.P., but it looks like there was a sticker over it, like maybe it was another horsepower??? The date on the pump template is 18 Jan 05. Can you help me with the correct new model to replace this one. Thanks so much.

A     Answered on 5/11/2018 by InyoPools Product Specialist Hector F.

If the motor that is on your pump is the original that came with the complete pump then yes it is model UCT1102

I have a model #94026110 1.5 hp . Is the model # 94027110 the same Pump? What would be a replacement if I wanted to go to a variable speed pump?

Hi Norman, This will be an exact replacement for your pump. you wanted to go variable speed, I would purchase a superflo

?     Asked on 8/31/2017 by Jerry

I have a question about the power consumption of the 1HP Magna flow. My old pump is a 1.5HP Hayward Maxflo. It has an Emerson motor that lists the current as “SF amps 8.7/7.8/15.6.” The service factor is 1.3. The Carvin motor lists the current as “Amps 7.0/14.0.” with a service factor of 1.25 Since it's comparing SF amps to FL Amps, I'm not sure the 1HP is lower power. Can you tell me what is the power consumption for both motors?

A     Answered on 9/1/2017 by InyoPools Product Specialist Lennox H.

Hi, Jerry. This Magnum Force Pump does have a lower power consumption and is a higher performing pump than the Max-Flo pump. You can use our How Much Does My Pool Pump Cost to Run? Blog to calculate how much either pump will cost to operate.

i need to replace a pool motor plus pump. The motor is a Century Centurion and the pump is a Jacuzzi - Magnum Force. The manufactures label for the motor shows 2.0 HP, but there is also a label that shows Total HP = 2.4. Question - what actual HP do i need? Thanks

A     Answered on 7/10/2017 by InyoPools Product Specialist Joe S.

Yes if you have a 2hp motor with a higher Service Factor then you would go with this unit. You can also go with Magnum Force V Series 2.7HP Variable Speed Pump (VMF-S2) - 94026140

A     Answered on 7/8/2017 by InyoPools Product Specialist Lennox H.

Hi, Bill. I would need to know the number of panels you have also. But I'm leaning towards recommending the Magnum Force Pump 1-1/2 HP Pump - 94027115.

Hi, I just bought the Jacuzzi Magnum Force 1 HP pump item number 94027110 last summer and its been running nice except when it gets wet from a rain storm it trips the breaker. Yesterday I turned it on and after about a minute it tripped the breaker. I reset the breaker and turned it on again but I saw a flash where the chord enters the motor and the breaker tripped again. Pump was dry. What the issue? Thanks.

A     Answered on 6/21/2017 by InyoPools Product Specialist Lennox H.

Hi, Mike. It sounds like the motor shorted.

?     Asked on 6/11/2017 by

A     Answered on 6/16/2017 by InyoPools Product Specialist Lennox H.

Hi. The flow rate is based on the pool's total dynamic head. You can use the steps in our How To Size a Pool Pump guide to calculate your pool dynamic head and using the Magnum Force User's Guide to determine GPH.

?     Asked on 5/11/2017 by Drew

My pump motor seized last season and the housing was cracked in a few different places. The previous owner didn't know the exact model or part # for the pump. The text on the side of the pump, model #, serial #, HP rating, etc are no long legible from age. This was the original install for the inground pool 15 years ago. The paper work I was given has the model # 1LR6 and 9402-7612 highlighted. If this is the pump i have, would this work for what I need? Thank you!

A     Answered on 5/11/2017 by InyoPools Product Specialist Patrick P.

Hi Drew this Jacuzzi 1 HP SLR Pump would be more comparable to your 1LR6 pump.

I have an A.O. Smith Century Centurion motor, Part 8-186086-20, Frame P56J, HP 1.0, SF 1.65. It mates to a Competition Pool Accessories (Canada) Magnum pump body. That company appears to be defunct. However, it looks identical to the Jacuzzi Magnum Force. The motor trips the GFCI when it is turned on. The motor has a melty electrical odor. Can you recommend a replacement motor? Thank you.

A     Answered on 4/24/2017 by InyoPools Product Specialist Stacey M.

Hello, According to the 8-186086-20 it matches with Motor 56j Thrd Full Ee 1hp (b654).

A     Answered on 4/23/2017 by InyoPools Product Specialist Patrick P.

Hi Walter, no this pump would not be an exact fit for the 94027802. If you are wiring your pump 115V then the Jacuzzi / Carvin SLR Pump would be the exact replacement.

I have a Jacuzzi impeller connected to a GE 3/4 HP motor (with Jacuzzi label). Jacuzzi info: Model #: 7H4187-S Order #: 91322420 Date: 19 Mar 94. GE motor frame size: 56C The GE jet pump motor works great, but the impeller has died. Where can I get a replacement for the impeller? Happy to send pix if needed.

A     Answered on 10/4/2016 by InyoPools Product Specialist Scott W.

If it is a Jacuzzi Magnum pump, I would need to know the diameter of the impeller as well as the thickness to identify the correct replacement impeller.

My old Jacuzzi Magnum pool pump, 3/4 hp, running on 115v needs a new plug, four wires come out of the pump in a cable; white, red, black and a ground. The pump has always had a single speed. I know where the ground goes, however not sure for the other three wires, do two of them double up on one terminal?

I have a Jacuzzi # 94027110 and the motor doesn't start. I took the back cover off and can turn the shaft. How do I check if I have a bad capacitor? And if I have a bad capacitor do you sell the capacitor by itself? and if yes how much does it cost?

A     Answered on 9/9/2016 by InyoPools Product Specialist Stacey M.

Hello Jeff, depending on what your motor model is we can check to see if we carry it for the Jacuzzi Magnum model. If you would like to double check with Jacuzzi 866-979-4501 to check with a tech on your motor specs to get you the right capacitor.

Hi Cris, You will save on your operational costs by going with a variable speed pump. Our article on How Much Does a Pool Pump Cost to Operate goes into this in greater detail. The Speck Variable Speed Pump would be a good option for replacing a Jacuzzi Magnum Pump with a variable speed pump.

Est. Repair Time

1 to 2 hrs

Tools Needed

Screwdriver, plumber's tape for pvc connections

our pump failed

Written on 12/14/2017 by Guest

We ordered a new pump from Inyopools. It arrived in a few days. The pump did not come with a cord so we had to take the cord off the old pump. Basically this was just a matter of attaching the cord, attaching the plumbing connections from the pool and to the filter, plugging it in, priming it and turning it on. No problem. We did have a friend of ours (an electrician) check the wiring to make sure we had done it correctly (we had). This pump replaced an older Magnum pump so the plumbing was easy to reconnect.

Were these instructions helpful?

The pool pump was making some very unusual noises (bad bearings)

Written on 12/28/2016 by Michael M.

Start with electrical. Turn off power, check voltage; both conductors phase to phase and phase to ground . Check voltage again, even check between the phase conductor and the dirt (just to be sure). Disconnect power conductors within the motor and remove from housing. Plumbing; loosen the two union connectors and the pump and strainer housing are ready to remove. Reversing the process is straightforward; you will need to ensure the threaded adaptors are not overtightened, you can damage the pump. The time spent was more about running around finding tools and plumber's tape than actual hands on the pump. Well prepared and organized, 45 minutes.
