Electric pumps marking

Насосы ЦГ и насосы БЭН могут устанавливаться во взрывоопасных зонах в соответствии с маркировкой IExdsIIBT4 (для насосов 1ЦГ 25/80-11-5С,  4ЦГ 50/50-11-5С,  4ЦГ 50/50-11-6С — маркировка IExdsIIBT2). Изготавливаются на одно из напряжений 380,  415, 500,  600 В (оговаривается при заказе). Материал проточной части: 12Х18Н10Т (исп. К) или 10Х17Н13М2Т (исп. Е) или ст. 3-10 (исп. А) (оговаривается при заказе).

В комплект поставки насосов (в зависимости от типа) входит: токопроводящий кабель, пускозащитные и измерительные устройства, запасные части, инструмент, принадлежности. Комплектность может быть изменена по желанию заказчика.

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  Н.

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.

SYMBOLS USED FOR THE HERMETIC PUMPS

An example: in a symbol of the electro pump 1ЦГ 12,5/50К-4-2 it is specified:

1 - a serial number of modernization;
ЦГ - 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;
К - made of a material of a flowing part (speed of corrosion should not exceed 0,02mm/year);

А - carbonaceous steel;
Е - steel hromnickel

  • 10Х17Н13М2Т GОSТ 5632-72;
  • 12Х18Н12М3ТЛ GОSТ 977-88;

К - steel hromnickel'malibden

  • 12Х18Н10Т GOST 5632-72;
  • 12Х18Н9ТЛ GOST 977-88;

К1 - steel hromnickel'malibden

  • 12Х21Н5Т GOST 5632-72;
  • 10Х21Н5ТЛ GOST 977-88.

4 - rated power of the built - in engine, kw;
2 - depending on a design 1, 2, 3, 4, 5, 5с, 6, 6с the temperature and pressure pump over liquids should be following:

  • 1 from - 500С up to + 500С (16 atmospheres.)
  • 2 from - 500С up to + 1000С (16 atmospheres.)
  • 3 from + 1000С up to + 3600С (15 atmospheres.)
  • 4 from - 500С up to + 500С (50 atmospheres.)
  • 5 from - 500С up to + 1000С (50 atmospheres.)
  •  from + 500С up to + 1000С (50 atmospheres.)
  • 6 from + 1000С up to + 3600С (44 atmospheres.)
  •  from + 1000С up to + 3600С (44 atmospheres.).
