F3000 Chopper

For pumping stations in public and institutional facilities
Every district has at least one - nightmare of a pumping station. A pumping station that is always subject to clogging. A pumping station that requires more time and attention than all the other stations in the district put together. You find them in places like train stations, hospitals, prisons and hotels: places where all kind of things gets flushed down the toilets, both fibrous and solid. Places that demand all too frequent emergency calls.

Getting the chop 140 times per second
But there is a solution: a Flygt chopper pump. Equipped with a special impeller and cutting plate, chopper pumps will cut up a wide variety of long fibrous materials and solid objects into small, harmless pieces, that will neither block up the pump, nor the piping.

The cutting action can be compared to that of a scissors. All stringy materials or solids that enter the inlet are forced by the S-shaped impeller into one of three areas in the high chrome cutting plate. There it is chopped up by the sharp, hardened edge of the rotating impeller. With an operation speed of over 1400 rpm, material passing through the pumps is chopped more than 140 times per second into harmless pieces.

For excess sludge sumps in sewage treatment plants
Every now and then, something can get through the screens. It could be the remains of a plastic bag, rags, or a pair of nylon tights. If you are unlucky, the material will rap itself around the impeller of a centrifugal pump, putting it out of action.

The resulting clogging can occasionally lead to flooding. And a breakdown always requires attention; in some sumps several times a month. It is an expensive and inefficient use of personnel and resources.

Protection against impeller jamming
The motor and shaft are protected from mechanical damage, should hard solid objects become caught in the cutting area.

The largest pump in the range features a unique automatic safety clutch. If a stoppage occurs, the obstructing article is easily removed, either manually, or by running the pump in reverse, and the unit is ready again for action.

For especially thick sludge, the screw-shape design of the impeller works to feed the denser medium through the pump.
