I have a Jacuzzi Magnum force pump

Where is it leaking? if it is still leaking between the wet end which is the black plastic water housing and the motor then the seal is not properly set.

the pump is pumping and circulating hot water into jacuzzi, it will get hot. I think it is ok

your pump should be just fine once the water starts flowing again. You may have run it too long without enough water to cool the seal.
If it is leaking water between the Jacuzzi Pump housing and the motor then you will need a new pump seal. Those are common pool parts.

Hi,
If you haven't already figured out how to change the seals on your Jacuzzi Magnum Force pump, I can help by supplying a diagram.
Here is the parts explosion for that pump.
Start by removing the case/basket assembly, then the diffuser to get to the impeller. Loosen the impeller to get to the seal plate.
When going to the trouble of changing the shaft seals one should change all the hosing seals at the same time because its a lot of work.

the pump housing is available through your local pool dealer. It is broken down into 3 sections the pump, housing and Pod.

The Pool Tech

The coupling between the pump and motor may not be tight and therefore may be sucking air and not allowing the strainer basket to fill with water.

you need to replace the shaft seal.

Pumps will **** all sorts of debris and many times the debris is small enough to get thru the strainer baskets and block the pump inlet. Turn the power off at the breaker, remove the strainer basket, and reach in with your fingers and check for debris in the pump inlet.
Clear all you can get out by hand, then on the outside of the pump motor, take the cap off the shaft, and turn it back and forth with a crescent wrench. Then put the basket and lid back on and turn the pump on.... you may need to clear it this way a few times to get it back up to speed, but that sounds exactly like what I've been dealing with at my wonderful pool that's right next to a 50 evergreen dropping needles 24-7 this time of year.... hope you clear it up ....let me know how it goes.

The number one problem is air leaks.......check all connections to see that they are tight, and rubber seals. The intake side would give you trouble with air leaks. If you dont find any leaks then I would pull the pump cover and check the impellor. Pool stores have parts and lots of knowledge.

With the Jacuzzi Magnum pool pumps, low pressure is going to likely be cause by one of the issues below. Try these troubleshooting tips.

1.Pump not primed

2.Leakage of air into suction system

3.Impeller clogged

4.Valve in suction or discharge line partly closed or suction or discharge line partly plugged or too small. 5.Plugged basket in skimmer or hair in lint strainer.

6.Dirty filter.
