Under the program of modernization and technical re-equipment of energy units there occurred the necessity to replace existing feeding pumps ПЭ-380 for pumps with increased parameter and higher characteristics, due to increasing of energy unit capacity up to 200MW( current capacity-170MW) using existing basement and fitting.

Tasks of project:

1) Replacement of worn pump units for modern with increased output of pump and using existing basement,
2) Providing min. delivery term taking into account the period of reconstruction and put energy unit into operation

The selection of equipment was determined by:

1. Usage of modern and reliable equipment.
2. Max. unification with equipment in operation at pump station( external casing of pump is the same as in existing one).
3. Optimal delivery and erection terms.

Pump ПЭ-580-185-5 by JSC “Nasosenergomash “Sumy” was offered as the optimal variant. This pump has detailed reference list, positive comments from maintenance departments, best ratio price/quality and it requires all technical specification of GRES.

Centrifugal pump, horizontal, many –staged one-side impeller, double casing with section inner casing, and drive from electric motor. Rotor support-sleeve bearing forced lubrication. End seals.
