Units
are made for
general usage
and for export
to climatic
modifications У
and Т in
accordance with
GOST 15150.
Application
field:
industrial and
household water
supply,
irrigation of
agricultural
lands, iodine
output, oil
production and
gas extraction
on a sea shelf,
etc.
Key parameters
on a nominal
mode, EFFICIENCY
and the basic
sizes of units
should
correspond to
specified in the
table.
Rotation speed
(synchronous) of
a shaft of units
compounds 3000
rev/min.
The values of
the backup are
specified for
work of units on
water with 25°C
temperature and
barometric
pressure above a
free surface 0,1
standard air
(760 mm Hg)
It is permitted
to use in units
electro-engines
of other
capacities if it
does not
contradict GOST
10428, with
respective
alteration of
EFFICIENCY.
The deviation of
values of head
from specified
in the table
should not
exceed:
±10 % for units
with head up to
50 m;
+ 10 % ...-6 % -
for units with
head over 50 m.
Schedules are
intended for
definition of
values of a head
and water
delivery in
cases if they
differ from
nominal (for
information).
Units are
produced on
rated power 380V
at frequency of
an alternating
current of 50 Hz
in accordance
with GOST 12139.
For the units
maintained in
conditions with
upstream
pressure below
atmospheric, the
value of
positive suction
head should be
determined in
GOST 10428, thus
the unit should
be shipped under
a water level.
Technical
requirements,
values of
weight, capacity
of the electric
motor,
EFFICIENCY and
maximum
deviations of
head for units
made to order,
are established
in conditions on
delivery.

ADVANTAGES of
PUMPS of JSC
“The Plant "Мolot”.
-The rotor of
the engine is
copper-filled,
that is
increased in
service life not
less than in 2
times.
-Can be
established a
new axial
bearing and unit
of step-bearing
is modernized ,
it is increased
a service life
of pump units in
1,5 times and
made an economy
of the electric
power (about 1
kilowatt/hour)
on 32 kilowatt
the engine.
-Each pump
passes test at
the stand.
-A guarantee
period.
