What Unique Features Exist?
Each Liberty sump pump has a quick disconnect power cord. A manufacturer designed detachable power cord means there is no potential for the motor seals to be broken during cord removal. This feature makes it extremely quick and easy to replace the motor power cord. In addition, the standard power cord length is ten feet. All model series also have a purchase optional power cord length of twenty-five feet.
What Float Options Are Available?
Each Liberty pump series has four float options. The float options include: no float and therefore a manual pump, a tether float, a piggyback tether float switch allowing manual operation or automatic operation, or a vertical magnetic float. The vertical magnetic float switch works differently in that a magnet is used to close the circuit and activate the switch which turns the pump on. The mechanical float switches depend upon a small ball to rock back and forth. When the ball is in one direction as the float rises because the water in the sump pit is rising, it closes the contact which activates the switch and turns the pump on; when the ball rock in the other direction as the float lowers because the water in the sump pit lowers, the circuit is open and the pump turns off.
Which Liberty Sump Pumps Are Made From Aluminum?
Uniquely the Liberty Pump 230 and 450 Series are made from aluminum. The manufacturer claims the deep finned aluminum body cools the motor better than cast iron; therefore the life of the motor is extended. The Liberty Pump series 240, 250, 280 and 290 bodies are made from cast iron.
Are Liberty Sump Pumps Made In The USA?

What Is The Motor Shaft Made From?
All pumps have a stainless steel rotor shaft. Many pump manufacturers use engineered plastic. Stainless steel is much stronger and therefore more durable.
What Does It Mean That Liberty Sump Pumps Are UNIBODY?
Unlike other sump pumps the Liberty Pump Series 240, 250, 280 and 290 are UNIBODY. This means the body is one-piece cast iron which eliminates the motor seal ring. This eliminates the potential for a motor seal ring break and leak.
Pump water to within 1/8 inch of the sump basin bottom with the 230 and 450 Series. Pumping water to such a low level is possible because the base is removable. Note the stainless steel bolts that can be loosed to release the base from the body.
What Kind Of Impeller Design Is Used?
Clog resistant designed impeller is used in the Liberty Pump Series 230, 250, 280, 450. The 240 Series has a modification of the vortex impeller using an eight-vane impeller and the 290 series using a semi open impeller.

Do Liberty Sump Pumps Come With An Anti-lock Hole?
