Strongest Features

The Liberty Pumps 257 Cast Iron Automatic Submersible Sump appears to have all that is needed to make it one of the best submersible pumps on the market. It is durable, has a great power output, and can handle light to medium-duty applications while being easy to install and remove. Let’s take a look at some of the best features this sump pump has to offer.

Design and Build Quality

Liberty’s pumps are known for their excellent construction, and the Liberty Pumps 257 Cast Iron Automatic Submersible Sump Pump does not disappoint. The product boasts high-quality cast iron construction destined to survive by possessing a single-body housing. It ensures that there are no links and wedges through which water can make its way into the interior of the pump unscathed even under heavy water pressure.

Taken together, these also allow the product to work flawlessly without needing a regular change of weakened joints and sealings. However, the product is slightly heavy and lacks a handle, making it a bit harder to carry around. However, this should not be an issue because the sump pump is generally meant to be placed in one sump for years.

To guard against the other danger – corrosion – the company has baked the cast iron housing in an epoxy coating that prevents corrosion from taking place over time. This is especially important given that sump pumps have to spend considerable time submerged under water and, if attacked by corrosion, can suffer malfunctions and leakages that become a health hazard over time.

Major external parts (discharge and power cord)

The Liberty Pumps 257 Cast Iron Automatic Submersible Pump has a standard 1-1/4″ NPT that can support any major PVC pipe of the appropriate diameter. It will save you from the hassle of resizing the PVC pipe to make it compatible with the pump. Further, the discharge can handle solids of up to ½” diameter, ensuring that small pebbles and debris are efficiently removed.

Further, the product has a 10″ power cord that can be extended up to 25″ with a replacement cord for those who prefer not to change their home/commercial establishment’s wiring to support the sump pump. Interestingly, the power cord features the Quick-Disconnect feature, which allows one to plug out the power cord at a moment’s notice without fearing the sealing that attaches the power cord to the motor.

This is a great innovation considering that the sump pump is placed in a delicate installation, and quick removal and replacement of power cables is therefore not feasible. On the other hand, however, it would have been great if the company had provided the 25″ cable by default instead of offering a 10″ default cable.

Motor and Sealing

Given the reputation Liberty Pumps has for good motors, it is no surprise that the Liberty Pumps 257 Cast Iron Automatic Submersible Sump/Effluent Pump comes with a 1/3 HP motor that can pump 50 gallons per minute at 1′ head, and this changes to 10 gallons per minute at 40′. 

Furthermore, the motor is permanently oiled, ensuring that there is never an issue of poor lubrication when it comes to Liberty Pumps 257 Cast Iron Automatic Submersible Sump/Effluent Pump. As one would expect of a top-of-the-range sump pump, the motor is hermetically sealed, and it is highly unlikely that the pump will ever malfunction because of water seepage into the motor or oil leaking out of the product.

Finally, the product bearings are also hermetically sealed and lubricated for posterity, so they will continue to work efficiently over long periods. In addition, they will never come into contact with water and debris that might damage or dislocate them.

Impeller and Switch Assembly

The Liberty Pumps 257 Cast Iron Automatic Submersible Sump/Effluent Pump has a vortex impeller made of an engineered polymer, allowing the water to move without getting entangled in debris. Indeed, it also helps the product handle water pressure better. On the other hand, the switch assembly is handled with a specific mechanism called the Vertical Magnetic Float (VMF).

As the name suggests, it is a vertical float connected to the switch by a magnetic assembly. When the water rises, the float activates the magnetic assembly, which interacts with the switch to cause the product to begin pumping water out. An additional benefit of the VMF is that it needs just a 10″ sump diameter, which allows it to work in even the narrowest sump possible.

Warranty

Though the excellent construction does not make a warranty a top-most concern, it is still heartening to know that the company has enough confidence in the product. to offer the Liberty Pumps 257 Cast Iron Automatic Submersible Pump a 3-year standard warranty, which easily outdoes the majority of warranty offers of the competition.
