Execution
The electric submersible sewage pumps have been specially designed to operate submerged in the pumped fluid.
The hydraulic section is close coupled to the electric motor making the pumping unit compact, easy to install and reliable in operation.
The pumps are essential in depuration systems and are widely used in the sewage handling facilities of industry and local communities.
The GK series electric pumps are designed to pump sewage containing gas, compacted solids and long fibrous material.
The pumps can be supplied for fixed or submersible installation with base frame.
The design has paid particular attention to achieving a good overall efficiency to ensure that the pumps are as cheap as possible to run.
Applications
RETRACTED VORTEX IMPELLER
The impeller offers reliability against clogging due to the feature of wide through passages, and a good resistance to wear thanks to the absence of shimming. The versatility of use compensates for this impellers somewhat lower efficiency.
The impeller can be reduced in dimension to offer different characteristics.
For water containing a large amount of solids and long fibre, sewage with a high gas and sludge content.
SINGLE-CHANNEL IMPELLER
It offers reliability against clogging and features wide through sections and a good resistance to wear, low mechanical action on the fluid, high hydraulic efficiency.
Particularly suitable for clean water, water containing solid and fibrous solids, cloacal water, sewage and sludge.
Low vibrations thanks to the dynamically balanced impeller.
DOUBLE CHANNEL IMPELLER
It offers reliability against clogging and features wide through sections and a good resistance to wear, low mechanical action on the fluid, high hydraulic efficiency.
Particularly suitable for clean water, water containing solid and fibrous solids, cloacal water, sewage and sludge.
Low vibrations thanks to the dynamically balanced impeller.
SHREDDER
Made of very hard stainless steel, the shape of the shredder ensures long-life and fade-free shredding capacity.
Waste water disposal from gas stations, community housing and neighbourhoods.
No particular tools are required to replace this part.
