Models
- Pumps ÖÃ and ÁÝÍ can be installed in the explosion hazard zones according to grades IExdsllBT4 for pumps (1ÖÃ 25/80-11-5S, 4ÖÃ 50/50-11-5A, 4ÖÃ 50/50-11-6S-grade IE-dsllBT2). They are used for one of the voltages 380, 415, 500, 600V (specified in the order) Channeled part materials: 12Õ18N10T (des. K) or 10Õ17N13M2T (des. E) or p.3-10 (des. A) (specified in the order).
- A set of delivering pumps (depending on their types) consists of: power cable, start-protective and metering devices, spare parts, tools, and accessories. A complete set can be modified at customer’s will.
Determining technical parameters of the pump are submission, a pressure and pressure and temperature. Submission is a volume of the liquids submitted by the pump in unit of time, expressed in one m3 / hour (cubic meter in an hour) or l/second. It is designated Q.
The pressure is a different specific energy liquid in sections after and up to the pump, expressed in meters of a water column. It is designated Í.
At a choice of the pump it is necessary to take into account disorder of parameters of the pump on submission and a pressure, including at various turning the driving wheel, and also an opportunity of a finding of a required mode of operation within the limits of working area of its characteristic.
A designation of the pump equipment.
An example: in a symbol of the electro pump 1ÖÃ 12,5/50Ê-4-2 it is specified:
1 - a serial number of modernization;
ÖÃ - type of the electro pump (centrifugal, tight);
12,5 - submission in cubic meter of a liquid in an hour;
50 - a pressure in meters of a column of a liquid;
Ê - made of a material of a flowing part (speed of corrosion should not exceed 0,02mm/year);
À - carbonaceous steel;
Å - steel hromnickel
10Õ17Í13Ì2Ò GÎSÒ 5632-72;
12Õ18Í12Ì3ÒË GÎSÒ 977-88;
Ê - steel hromnickel'malibden

4 - rated power of the built - in engine, kw;
2 - depending on a design 1, 2, 3, 4, 5, 5ñ, 6, 6ñ the temperature and pressure pump over liquids should be following:
1 from - 500Ñ up to + 500Ñ (16 atmospheres.)
2 from - 500Ñ up to + 1000Ñ (16 atmospheres.)
3 from + 1000Ñ up to + 3600Ñ (15 atmospheres.)
4 from - 500Ñ up to + 500Ñ (50 atmospheres.)
5 from - 500Ñ up to + 1000Ñ (50 atmospheres.)
5ñ from + 500Ñ up to + 1000Ñ (50 atmospheres.)
6 from + 1000Ñ up to + 3600Ñ (44 atmospheres.)
6ñ from + 1000Ñ up to + 3600Ñ (44 atmospheres.).
