"APH" electric pumps
"AHP" pumps - centrifugal, submersible, vertical, one-stage with the open driving wheel. Are intended for pumping of chemically active and neutral liquids with a density no more than 1850 kg/m3, viscosity to 30х10-6 sq.m / with, containing firm inclusions up to 1 mm in size, volume concentration of which does not exceed 1,5% for which the speed of penetration of corrosion of metal of flowing part does not exceed 0,1 mm/year.
Temperature of the pumped-over liquid from 233 to 393 To (from - 40 to +120oC)
Consolidation of a shaft of the pump - double stuffing or double face.
Material of details of flowing part of the pump:
- chromonickel steel 12H18N9TL-"K";
- hromonikelmolibdenovy steel 12H18N12M3TL - "E";
- hromonikelmolibdenomedisty steel 07HN25MDTL - "And".
Pumps are issued in common industrial and fire and explosion safe executions.
The symbol of the pump corresponds to GOST 10168.1-85
AHP 50-32-200-1.3-K-SD-U2, where:
AHP - pump type (for liquids with abrasive particles, chemical, submersible);
50 - nominal diameter of an entrance branch pipe, mm;
32 - nominal diameter of an output branch pipe, mm;
200 - nominal diameter of the driving wheel, mm;
0,8 - symbol of depth of immersion, m, or
1,3 - depth of immersion, m;
2,0 - depth of immersion, m;
2,5 - depth of immersion, m;
To - a symbol of material of details of flowing part (steel 12H18N9TL), or
Е - steel 12H18N12M3TL
And - steel 07HN25MDTL
SD - a symbol of double omental consolidation of a shaft of the pump;
At - a climatic modification;
2 - category of placement of the unit at operation.
The same pump with turning of the driving wheel and double face consolidation of a shaft of the pump has designation:
AHPE 50-32-200a-2,5-K-55-U2, where:
Е - a design for explosive and fire-dangerous productions;
and - turning of the driving wheel;
55 - symbol of double face consolidation.
