Application and design:
The pump units are used in the steam-and-water lines of the electric power
stations being running on the organic fuel. The pump unit consists of the
pump and electric motor connected by means of the coupling with
rubber-bushed studs. The main (fast-running) stage of the pump is provided
with one or two impellers which are set on the fast-running shaft,
supported by the rolling-contact bearings and the plain ones. The double
end-face seal and the coupling with rubber-bushed studs are arranged on the
shaft. The booster slow-going stage receives the rotation from the water
wheel positioned in the flow of the liquid being pumped just behind the
impeller of the main stage. The booster stage rotates in its own sliding
supports aligned with the hydrostatic pivot. The booster wheel is
positioned on the slow-going shaft. The supporting point for the attachment
to the foundation is made integral with the pump case.

Liquid to be pumped:
The pump units of 1KsV type are designed to pump condensate or fresh water
at a temperature of up to 433 K (160°C), with pH 6,8:9,2; and having a
concentration of solid inclusions not exceeding 5mg/l and a maximum size
the said inclusions of up to 0,1 mm , at an abrasive resistance not more
than 6,5 GPa.

Conventional alphanumeric designation:
For example:
1KsV 125-71-1 YXL4 or 1KsV 125-71-1 T2
where 1 - serial number of modernization;
KsV - is the condensate vertical pump;
125 - is the capacity, m3/h;
71 - is the head, m;
1 - is the design code;
YXL4 or T2 - are the climatic version and location category.
Conventional designation of the characteristic curves:
Q - is the capacity, m3/h;
H - is the head, m;
N - is the maximum power consumption, kW;
n - is the frequency of rotation, rpm;
 -
efficiency, %;
 - is the admissible positive suction head, m;
