    Solids Handling
    To prevent clogging, a vortex impeller is used on the - 230's (can handle 3/8 inch solids) and 250's (can handle 1/2 inch solids). The 280's and 290's have a bottom screen; however they can handle solids up to 3/4 inch in diameter. The 240's have peripheral ports which are located about two inches from the base and have no bottom suction.  
     
    HorsePower and Pumping Capacity
    The 240's are 1/4 horsepower with 1380 GPH pumping capacity at 10 foot vertical height. The 230's (with 1800 GPH pumping capacity at 10 foot vertical height) and 250's (with 2160 GPH pumping capacity at 10 foot vertical height) are 1/3 HorsePower.

    Shut Off Head
    The 280's are known for their high head. It shuts off at 37 feet. The 290s shuts off at 47 feet; The 450's  shut off at 33 feet. The other models shut off between 20 feet and 22 feet. 
     
    Cord Length
    The standard cord length for all Liberty Submersible pumps is 10 feet.
     
    The following models can be purchased with a 25 foot length cord. The 233-2; 250-2; 251-2; 253-2. 257-2, 283-2, 287-2, 290-2 and 457-2. The addition of the suffix -2 indicates a 25 foot cord.
     
    The following models can be purchased with a 35 foot length cord. The 250-3; 251-3; 253-3, 280-3, 283-3 and 290-3. The addition of the suffix -3 indicates a 35 foot cord.

    Pit Diameter Size Required
    The models ending in xx1 and xx3 (tether wide angle floats) require  a 14 inch pit diameter. The models ending in xx7 (vertical magnetic floats) require a 10 inch pit diameter. 237 abd 247 can operate in a 9 inch diameter sump pit.
     
    Discharge Port Size
    All models have a discharge port size of 1 1/2 inches. If your discharge piping system is 1 1/4 inches, a discharge reducer can be installed though pumping capacity is reduced.
     
     
    Pictured are the Liberty Model 247 Model 257 and Model 287 Submersible Sump Pump.
     
    Built to last
     
    The Liberty 240, 250 and 280 and 290 series are very well built.
     
    The pump housing is cast iron. Cast iron has superior strength compared to aluminum or thermoplastic. It is difficult to destruct. Cast iron also has the following beneficial characteristics: it withstands the motor temperatures of a pump that runs continuously for an amount of time; it is wear resistant; it is not destructible and is not weakened by oxidation (rust). The cast iron has a durable epoxy powder coat finish which increases the toughness of the iron.
     
    The volute intake plate, rotor shaft and fasteners are made from stainless steel. Stainless steel is strong, corrosion and heat resistant. 304 grade steel, the most commonly used grade of steel, is found in the 240 series pumps. 416 grade steel is used in the 250, 280 amnd 290 series pumps since their pumping capacity is higher and thus they work harder.

    Fits small pits
     
    The vertical magnetic float switch requires very little room. It moves up and down with no chance of getting hung up on the pit wall. The float itself is very narrow.

    The 237 and 247 can operate in a 9 inch diameter pit. The 257, 287, 297 and 457 require a 10 inch diameter pit.

    Unique motor housing design
     
    The Liberty sump pumps have a one-piece cast iron housing. This is unique for submersible sump pumps since other models have two places where where there are seals - top and bottom of the housing.
     
    The uni-body of the Liberty pump eliminates the need for the bottom seal and the lower seal ring and consequently the potential of bottom ring seal failure.
     
    Uni-Body Housing used for Liberty Submersible Sump Pumps
     
    Non clog impeller
    The Liberty sump pumps are designed to prevent a clogging impeller. Every sump pump has some debris or pea gravel that collects in the bottom of the pit.  When the impeller gets stuck the pump will not work; therefore a non clogging design is important.
     
    The Liberty 230's, 250, and 450 Model non clogging design includes a 8 vane, glass reinforced thermoplastic impeller. The more vanes the more protection from clogging. In addition these models do not rely on bottom suction.
     
    The 240's have peripheral-port inlets which are 2-3 inches from the bottom of the pump. There is no bottom suction. This pump is designed to handle 1/4 inch solids.
     
    The 280's and 290's have bottom screens; however they are built to handle 3/4 inch solids. The pumps are raised slightly by legs so do not sit directly on the basin bottom.

    Detachable/replaceable power cord
     
    A detachable/replaceable power cord is a common feature of all Liberty submersible sump pumps. This feature allows you to quickly disconnect the cord without breaking motor seals. Liberty makes replacement cords should you need one. This is truly a unique feature.  For all other manufacturers brands of sump pumps the power cord cannot be replaced without breaking the motor seal.
     
    Go back to Liberty Sump Pumps Topics
    Liberty Submersible Sump Pump Power Cord can be disconnected.
     
    Long lasting float switch
     
    The vertical magnetic float switch requires very little room. It moves up and down with no chance of getting hung up on the pit wall. Notice how close the float switch is to the pump.
     
    The vertical magnetic float switch works differently that other float switched. The VMF float rises as the water rises. When the float reaches a pre-defined height, the magnet inside the float closes the circuit causing the pump to begin operation. 
     
    The float 'on' height for the tether models is 13 inches and the 'off' height is 7 inches. The float 'on' height for the vertical magnetic float switch is 9.5 inches and the 'off ' height is 4 inches.

    What are consumers saying (customer reviews)
     

    Consumers give Liberty submersible sump pumps a good rating. Here's what some customers are saying about the Liberty pump.

    Amazing Pump, October 11, 2014

    By Steven, (New Jersey)

    The Liberty 257 is literally silent. The vertical float keeps the water level low. I really like it. We had so much rain this fall and it did the job. I was so relieved that our basement did not flood during the flooded streets around us.

     

    Great Pump. It had high rating 4.8 out of 5 with 188 reviews  April 5, 2014
    By Steven, (New Jersey)
    The Liberty 257 is great. I bought it based on reviews I read plus it had the features I needed. I am so glad I bought it. It is such a good sump pump. It was very easy to install.
     
    I Like It, September 9, 2014
    By George (New Jersey)
    The pump is fast and quiet. I have a small pit. The vertical float switch works well in it. It seems to work up and down in a flawless vertical motion unlike others that get hung up on the walls of the pit. I installed it with a check valve so water doesn%u2019t run back in the pit once its pumped out. Liberty makes pumps far superior to what is sold in the big hardware stores and they even cost less.
     
     
    Another Good Pump, September 6, 2014
    by Stan White (North Salem, NY)
    With all the heavy rain in the midwest this fall, our old pump was going off every minute or so. I investigated to see how much water was coming in. There was a lot, but the real problem was we didn't have a chech valve so the pump kept pumping the same water after each cycle. Our old pump was around 20 yrs. old.  I decided I better put a new one in and use my old one in case I needed it. After lots more research, we decided on the Liberty 257. The Liberty 257 is cast iron and has a vortex impeller. It is also made in the USA. 
     
     
    Good Pump, September 3, 2014
    by Mike (South Salem, NY)
    I had a Liberty pump before. I had it for 15 years. I decided it was getting old so am keeping it for a replacement pump. I bought the Liberty 257 Model and am very glad I did. These Liberty pumps are good. They are American made.
