Calpeda Submersible pumps with multi-channel impeller - Gkn
Construction
Submersible pumps with multi-channel impeller.
Characterised by good protection against clogging, large spherical passages,
good wear resistance, low mechanical action on the fluid and high hydraulic
efficiency at high flow rates.
Low vibrations thanks to the dynamically balanced impeller.
Delivery port DN 200-250-300-350.
Applications
For the movement of sewage and sewage grates.
Particularly suitable for the emptying of sewage from cesspits or primary
collection tanks or industrial waste water.
They replace single-channel pumps when a high solids passage diameter is not
required.
Solid passage from 100 to 164 mm.
