Centrifugal vertical pumps for waste liquids СДВ type


 
Centrifugal vertical pumps are intended for pumping over the residential waste waters, industrial waste waters and other polluted liquids with a pH value from 6 to 8,5, with kinematic viscosity no more 1x10-6 m²/s, density to 1 050 kg/m³, temperature to 35°С, with the content of abrasive particles on volume no more than 1%.
Pumps are applied on treatment facilities of cities and industrial regions.
 
Pumps - centrifugal vertical with the unilateral input pump impeller. A drive is the electric motor. Water is brought to the pump through a metal knee. The sliding pilot-bearings is lubricated with water with the content of the weighed particles no more than 50 mg/l, the 1 l/s discharge, pressure more than in the pump for 1 kgf/sm².
 
Shaft has stuffing box seal or the rubber sealing end.
 
A symbol of the pump with addition to it of a climatic modification and a placing category in accordance with ГОСТ 15150: 
С – for waste liquids;
Д – dynamic; 
В – vertical;
figures in numerator – supply, m³/h;
figures in a denominator – a head, m;
 
The Example: СДВ2700/26,5-У3.
