Superior Pump 92751 3/4HP Sump Pump Review & Specifications
Let me present to you a popular sump pump, the Superior Pump 92751. This 3/4 HP pump is the preferred model for many homeowners that have a demanding basin. If you were browsing for a good sump pump, I’m sure you’ve seen it.
The reason why the SP 92751 is so popular is the price and durability. One of the cheapest high-performance durable pump models. Similar models are more expensive while not as good as this pump. Superior Pump may be known for its cheap pumps, this pump is exceptional though.
I know that there’s a high demand for this pump. And you’re probably one of the many that are researching reviews about this pump. I’ll give you my take on the 92751, based on facts that I’ve aggregated about the pump, and below I’ll supplement it with a table of its specifications. So, Let’s walk through the specs and finish with closing thoughts and see if it’s as good as they say, shall we?
Performance and Usage
This is a pump for high capacity pumping. It features a 3/4 HP motor with a strong performance. The normal discharge line is 2 inches which is adequate for high capacity pumping. There’s a 1-1/2 NPT adapter included though, for those that don’t need 2”.
It has a maximum flow rate of 4800 gallons per hour, more than enough for most demanding basins. The drop in flow rate as the discharge line lifts is not bad at all. It goes: 4500 GPH at 5 feet lift, 4140 GPH at 10 feet, and 2700 GPH at 25 feet.
I consider this to be a pump with a broad range of uses. It can’t be used in basins with low water income, it will handle the water fast. Hence, it will pick up dirt too much. If you need a sump pump with less power you may want to look at the Superior pump 92250 instead, which has 1/4 HP.
The 92751 will handle any demanding basin though. Storms, continuous duty, it can handle it all. It can be used as a utility pump too. When it comes to the discharge lift, it handles most heights, as you can see it handles 2700 GPH at 25 feet lift.
Pump Construction
You’ll find the construction just as impressive as the performance. Despite being relatively cheap, the pump has high-quality construction. It will be effective and reliable even in harsh basin conditions.
Featuring a stainless steel/cast iron construction. The pump housing is made from stainless steel, the base from cast iron. This is what durable quality pumps usually have. So this is not the kind of pump that you’d expect to corrode. The impeller is not as good though, only thermoplastic.
Pump Motor
Even though we’ve gone over the pump’s performance, the motor deserves a separate section. The high performance is not the only thing good about this motor, the design is really good.
A thermally protected 3/4 HP motor. The pump should not burn out, it can handle liquid temperatures up to 120 F. The temperature is not bad considering how the pump can handle continuous duty. It can work for hours, especially good when there’s a heavy storm that lasts a whole day.
I wouldn’t call it energy-efficient but it does really well in terms of power usage. It features a permanent split capacitor motor which saves energy if the pump is on continuous duty. The pump only draws 7.5 amps, which is quite excellent for such a powerful pump.
Pit Size and Turn On Point
I really like that the SP 92751 can fit in most basins. It’s not big at all, considering how it’s a high-performance, heavy-duty pump. There are two versions of this pump. You can either get it with a vertical float or a tethered switch.
The basin diameter requirements depend on what kind of float switch you’ll choose. The preferred model among homeowners is the one with the vertical float. Mainly, because the basin diameter can be smaller with the vertical switch. A tethered float means you’ll need a larger basin.
Automatic operation is supported by a vertical float switch or a tethered float. The turn-on point is different for each switch. With a vertical float, the turn-on point is at 8.5 inches. It turns off at 3 inches. With the tethered, it turns on at 16 inches and shuts down at 8 inches.
Clogging and Solids Handling
Now, a high-performance pump can’t be considered a good pump without the ability to handle solids. As expected, the 92751 can handle solids and has protection against clogging.
Superior solids handling ability. It can handle solids as big as 1/2 inches in diameter. This comes in handy, especially if you’re using the pump in effluent waters.
The pump is clog-resistant. There’s an intake screen that is really easy to remove and clean. The impeller has a clog-resistant vortex design. This is just a testament to how good the pump performs in harsh basin conditions.
Using the 92751 as Utility and Effluent Pump
I’ve said that this pump has a broad range of uses. By removing the float switch, you can use it as a utility pump. With its high performance, it will clean ponds and pools in minutes.
You can also use it in effluent water. The hot dirty water will be no problem for this pump. Make sure to do the usual maintenance if using it as an effluent pump.
Our Review of the SP 92751
There we have it, those were the specs. Do you like what you see so far? I know the specs are just meaningless words for some. So, we make an effort to leave a review at the end.
I honestly like this pump. It’s affordable for every homeowner. A great choice for those that need a high-performance, durable pump. It comes with a 3-year warranty and saves money long-term because of the low energy draw. These are all pros.
The only bad thing about this pump is the impeller. Not that it’s garbage, you just want more in a pump like this. Seeing as how it handles large solids and handles effluent waters, a metal impeller would be nice.
We highly recommend this pump to homeowners that are on a budget but need a quality high-performance pump. Homeowners that change pumps a lot should try it too. It may work out, and you’re not spending a lot of money.
SP 92751 versus the SP 92731
I’d like to make one last remark concerning the difference between the 92751 and the 92731. The difference is basically non existent, but that’s why it may be confusing too.
The only difference between these two pumps is the float switch. In the model 31 there’s a tethered float switch, while the 51 comes with a vetical float. What system activates the pump doesn’t really matter all that much, but my personal preference would be a vertical float, as there’s less chance that it’ll get stuck and your basin doesn’t need to have too big a diameter. Consumers tend to agree with me, since the 51 is much more in demand.
