The centrifugal single -stage pump with a bilateral input of the liquid into the working wheel is produced in - for pumping water and similar to it in the viscosity and chemical activity of liquids with a temperature of up to 85 ° C. - for pumping water and similar to it in the viscosity and chemical activity of liquids with a temperature of up to 120 ° C (The temperature is additionally stipulated when ordering).
- for pumping water and similar to it in the viscosity and chemical activity of liquids with a temperature of up to 140 ° C - for pumping petroleum products with a viscosity of up to 120 sons with a temperature of up to 85 ° C. - for pumping petroleum products with a viscosity of up to 120 sons with a temperature of up to 120 ° C. - for pumping chemically active liquids. Production material of the running part - 12x18n9t.
The body and cover of the pump are connected in the horizontal plane along the shaft axis. Hydroving flanges and The pump is equipped with a salary or end seal of the shaft.
Pump tests according to the BDS EN ISO 9906: 2000+AS: 2006, technical data are given for water at The pump drive is carried out using an electric motor or internal combustion engine. The pumps are made in horizontal and vertical performance, which allows reducing the size of the pump station by 25-30%. |

The designation of the pumps includes the following: Example: 140D40A-4Y, 140DV40A-4Y 140 - nominal feed (rounded), l/s; D - centrifugal, single -stage, bilateral entrance; DV - centrifugal, single -stage, bilateral entrance, vertical performance; 40 - General pressure with nominal feed in MV.; A (b, c) - an option with a reduced diameter of the working wheel; Chu is the mechanical seal of the shaft. In the absence of this indication, the pump is made with a linest seal. |
