Popular Liberty Sump Pump Models:
The 1/3HP sump pumps are most common in the industry, with Liberty models such as S37, 237 and 257. The applications requiring higher flows would need a 1/2 HP sump pump, such as 457 model. For small applications, a 1/4 HP pump such as 247 model is best suited.

Which float switch type to choose?
Vertical mechanical float switch is the most popular on Liberty sump pumps, mainly because such pump will require the least amount of space and can be installed in compact basins.
Wide angle float switch is best for projects where space is not an issue. Due to the simplicity of the design, float switches are generally maintenance free and long-lasting.
Piggyback float switches are removable and are advantageous in applications where removing the whole pump is troublesome. This float type also the only one which allows to run the sump pump in both manual and automatic modes in case the float switch fails or manual dewatering is needed.

Selecting the right Liberty sump pump for your application:
Besides constriction materials and power rating, an important factor in purchasing a sump pump in knowing it's ON and OFF levels. The ON and OFF levels represent the water level at which the sump pump will activate and deactivate. These levels are factory set and usually have a small tolerance of 1 or 2 inches. Models with wide angle float switch may have the option of adjusting the ON/OFF levels by adjusting the height at which the float switch is located. Models with piggyback float switch will allow to mount it at any desired height in the proximity of the sump pump, making it more versatile for various sump basin sizes and depths.

For 25' cord on model numbers ending in "0", "1", or "7" add "-2" suffix.

Example: 253-2 = Model 253 with 25' cord
