But what sets these pumps apart from their peers? In this article, we'll take a deep dive into the world of Liberty Pumps 230 Series, specifically discussing the differences between the Model 230, Model 233, and Model 237.

Sump Pump

Model 230

Starting with the Model 230 all 230 series pumps are 1/3 Horespower and offer the same construction and materials.  The big difference in each model is the float mechanism or lack there of.   

The 230 offers a solid balance between cost and performance, providing efficient water displacement suitable for most residential applications. 

This model comes without a float switch, allowing you to utilize an existing float switch, or choose your own.  

Model 233

Next up is the Model 233. This model offers the same 1/3 horsepower performance as the 230, delivering a fast rate of water displacement, which might come in handy during heavy rainfalls or sudden water intrusions. 

This unit comes with a wide angle float switch with a series plug, which allows for manual operation of the pump and easy testing of the pump. 

Model 237

Last but not least, the Model 237 stands out with its unique VMF (Vertical Magnetic Float) switch, providing automated control over the pump operation. 

The VMF allows for operation in a 10 inch diameter sump pit.

One common factor among all three models is their 1/3 horsepower motor. This provides adequate power for most domestic sump pump and water moving applications, ensuring efficient operation.

Unique VMF Switch in Model 237
