Centrifugal pumps “D” are widely used at pumping stations of industrial, urban and rural water supply. Often used for irrigation and drainage of fields, as well as in other branches of agriculture.
These pumps are designed for pumping water or liquids similar to water in viscosity (36 SCT), as well as chemical activity having a temperature up to +85 ° C. The next content of solid inclusions is allowed - up to 0.05% by weight, with a size of up to 0.2 mm. And the admission to the vacuum meter height of absorption is 3-5.5 m.
Designations (on the example of the centrifugal pump 1D 200-90 a):
- 1 - first modernization
- D - bilateral entrance
- 200 - feed m^(3)/h. Possible values: 250, 315, 320, 500, 630, 800, 1250, 1600
- 90 - pressure, m. Possible values: 36, 50, 56, 63, 71, 125
- A - cutting wheel pruning
Consider the technical characteristics of the centrifugal pumps of D. since these pumps are successfully used in many sectors and have A fairly wide area of application, they can vary greatly in the frequency of rotation, supply and other parameters depending on the brand. The speed of rotation of the given pumps varies in the range from 1000 to 3000 rpm, feed - from 100 to 1600 m3/h, the pressure - from 20 to 125 m, and engine power - from 15 to 630 kW. Along with the pumps “D”, the list contains technical characteristics and modernized, that is, updated pump models-“1D”, for example, “1D200-90”, “1D315-50” and others.
| Pump brand | Feed, m3/hour | NAPAR, M.D. St. | Rotation frequency, rpm | Electric motor power, kW | Brands replaced according to the parameters of the pumps |
| D 500-65 | 500 | 65 | 1450 | 160 | 10D-6, 1D500-63 |
