"4D" electric pumps
"4D" pumps - centrifugal a bilateral entrance, horizontal one-stage are intended for the pumping of water and liquids similar to water on viscosity and chemical activity, with the temperature up to 358K (85os) with the content of the firm inclusions which are not exceeding on the weight of 0,05%, and their maximum size - 0,2 mm, with the micro hardness no more than 6,5 Gpa (650 kgfs/mm2)
- Consolidation of a shaft of the pump - unary, double stuffing.
- Material of details of flowing part - gray cast iron.
Pump symbol: 4D200-90-UHL4, where
- 4 - serial number of modernization;
- Д - pump type (bilateral entrance);
- 200 - giving, m3/h;
- 90 - pressure, m;
- UHL - a climatic modification;
- 4 - category of placement of the unit at operation.
The same pump with turning of the driving wheel has designation: 4D200-90a-UHL4, where
- and - the first turning of the driving wheel of the pump
