Sometimes you have to move a lot of water with a lot of crap in it — Little Giant designed this pump to do just that. With a submersible 1/3 HP motor, the 8E-CIM will pump 52 gallons per minute. Hook up your discharge hose, connect the 25′ cord to a power supply, and drop the sucker into the glop. It’ll handle solids up to 3/4″, with a 1-1/2″ discharge hookup, and it starts at $180.
Other trash pumps’ll move liquid with as much as 25% solids in it; some will lift water many feet; some will move huge volumes of water. You want to pick the right one for your needs, for the sake of both your pocketbook and the life of the pump. If the 8E-CIM isn’t the right fit for you, you can probably find one out there that’ll fit your current needs and give you plenty of options for future applications.
