Semisubmersible, vertical, with support out of the pumped-over liquid, for pumping of the hot and crystallizing liquids.
The given environment: are intended for pumping of chemically active and neutral liquids with a density no more than 1850 kg/m3, viscosity to 30x10-6 sq.m / with, containing firm inclusions up to 0,2 mm in size, volume concentration of which does not exceed 0,1%. Pumps let out from 7 to 600 m3/h and a pressure from 12 to 125 m on giving.
Temperature of the pumped-over liquid for pumps with flowing part:
from material A — from 233 to 363 To (from-40 to 90 °C);
from materials K, E, I, M, T — from 233 to 393 To (from-40 to 120 °C);
from material D — from 273 to 363 To (from 0 to 90 °C);
from material L — from 273 to 343 To (from 0 to 70 °C).
Pumps with flowing part from materials A, K, E, I, M, T let out in a climatic modification At category of placement 2, 3 in accordance with GOST 15150 — 69. The index "O" in HIO pumps designates "warmed", i.e. the shirt for heating by steam is provided in a design of pumps.
Symbol: HIO 45/90a-1,3-K-SD(Shch), where:
45 — giving, m3/h,
90 — a pressure, m,
and — a symbol of the driving wheel with the turning ensuring functioning of the unit
in a middle part of the field "Q-H",
1,3 — depth of immersion, m,
To — conditional designations of material of flowing part,
SD — a symbol of double omental consolidation.
Щ - slot-hole consolidation.
