NG pump 100

NG pump 100

Rimer of the convention of the NG type pump:
a) pumping fluid with a density of 700 to 1000 kg/m3, with a viscosity of up to 1 STA, explosion protection 1EXDSIIVT4 x:
Electric pump centrifugal sealant NG 25-50-1 SF 37267809-002: 2007 , where:
NG -type (sealed for neutral fluids);
25 -nominal feed in cubic meters per hour (m3/h);
50 -pressure with nominal feed in meters (m);
1 -constructive execution;
SF 37267809-002: 2007 - Designation of technical conditions;
b) the same with explosion protection 1EXDSIIST4 x;
Electro pump centrifugal hermetic NG 25-50-1C
SF 37267809-002: 2007;
c) the same with the density of the pumped liquid from 1000 to 1300 kg/m3 (option "a" of the working wheel) or from 1300 to 1600 kg/ M3 (option “B”), with a viscosity up to 3 SOST:
Electric pump centrifugal hermetic NG 25-50A-1 or NG 25-50B-1 SF 37267809-002: 2007 ;
g) the same with the density of the pumped fluid up to 700 kg/m3, with a viscosity of up to 3 STA;
Electro pump centrifugal hermetic NG 25-50-1L SF 37267809-002: 2007.
Notes
1.
  • Density - up to 1600 kg/m3 - for electric pumps NG;
  • up to 700 kg/m3 - for electric pumps NG (l);
  • viscosity - up to 40 SST - for electric pumps NG;
  • Up to 5 SST - for electric pumps NG (l);
  • temperature (see table);
  • The presence of solid non -abrasive inclusions is allowed up to 0.2 mm in size and up to 0.2% by mass.
2.
  • For NG electric pumps - for a working fluid with a density of 1000 kg/m3 and a viscosity of 1 SST;
  • For electric pumps NG (L) - for a working fluid with a density of 700 kg/m3 and a viscosity of 5 sst.
3.
Considering the viscosity, the pumps are delivered with reduced pressure due to the hardware of the worker
Wheels according to the outer diameter in order to exclude engine overload.
4.
  • up to 16 kgf/cm2 - for electric pumps of executions 1.1 l, 2.2l;
  • up to 40 kgf/cm2 - for electric pumps of executions 4.4l, 5.5 l.
5. Electro pumps are made to voltages of 380.660 V (stipulated when ordering), current frequency 50 Hz.
6. Explosion protection marking-1EXDSIIVT4 x or 1EXDSIIST4 X (stipulated when ordering).
7. more detailed information, including graphic characteristics, strain and control scheme, design and operation rules, indicated in the operational documentation for electric pump. < /div>
