Example of a conventional designation of the CH type canned motor pump pumping liquids with a density of up to 1000 kg/m3, a viscosity of up 1 cSt, with protection against explosion 1ExdsIIBT4 X:
Hermetically sealed centrifugal pump 3CH 100/50-K-30-5-У2 SF 37267809-002:2007, where:
3 – serial number of modernization;
CH - type (hermetically sealed centrifugal pumps);
100 - rated flow in cubic meters per hour (m3/h);
50 - pressure at rated flow in meters (m);
K - version according to material (see note);
30 – rated power of the built-in motor in kilowatts (kW);
5 – structural design;
У2 – type of climatic version and placement category according to GOST 15150-69;
SF 37267809-002:2007 - designation of technical conditions;
a) also with explosion protection 1ExdsIIST4 X:
Hermetically sealed centrifugal pump 3CH 100/50-K-30-5C-У2 SF 37267809-002:2007;
b) also with a density of pumped liquid from 1000 to 1300 kg/m3 (version ‘a’ of the impeller turning) or from 1300 to 1600 kg/m3 (option ‘b’), with a viscosity of up to 3 cSt:
Hermetically sealed centrifugal pump 3CH 100/50a-K-30-5-У2 or 3CH 100/50b-K-30-5-У2 SF 37267809-002:2007;
c) pumping liquid at a temperature below -40°C, at a density of 700 kg/m3 with a motor of a power, smaller than the basic version:
Hermetically sealed centrifugal pump 5CH 50/80-K-18,5M-4L SF 37267809-002:2007;
g) with superposed wheel (screw) in order to reduce acceptable net positive suction head:
Hermetically sealed centrifugal pump 4CH 100/125H-K-55M-4L-У2 SF 37267809-002:2007.
Notes
1. Characteristics of pumped product:
- density - up to 1600 kg/m3
(for hermetically sealed centrifugal pumps CH 25/12,5-3Б-1 and CH 50/12,5-5,5Б-1 - up to 1800 kg/m3);
- viscosity of up to 40 cSt;
- temperature (see table).
- availability of solid nonabrasive impurities – a size of up to 0,2 mm and up to 0.2% in terms of weight is admitted.
2. The parameters in the Table are given for operating fluid of a density of 1000 kg/m3 and a viscosity of 1 cSt.
3. When pumping liquids with a density of over 1000 kg/m3 and (or) taking into account viscosity, electric pumps are supplied with reduced pressure due to impeller turning on the outside diameter in order to avoid overloading of the motor.
4. Electric pumps of the less rated power of the same standard size, for example, 1CH 25/50-5,5-1 (2,3,4,5,6), are intended for pumping liquid of a density of up to 850 kg/m3.
5. Electric pumps are made at 380, 500, 660 V (specified when ordering), a current frequency of 50 Hz.
6. Mark of explosion protection:
- for electric pumps versions 1, 2, 4, 5 - 1ExdsIIBT4 X;
- for electric pumps versions 1C, 2C, 5C - 1ExdsIICT4 X;
- for electric pumps versions 3, 6 - 1ExdsIIBT1 - T4 X;
- for electric pumps versions 6 C - 1ExdsIICT1 - T4 X.
7. Electric pumps are available in the following versions depending on the material:
- A - carbon steel;
- E - stainless steel 1.4571, 12Х18H12M3TЛ;
- K - stainless steel 1.4878, GX10CrNi18-8;
- K1 - economically alloyed steel 12X21H5T, 10X21H5TЛ.
More detailed information, including graphic specifications, schemes of binding and control, description of the structure, installation and operation rules, are specified in the operational documentation of the electric pump.
