PJSC “Sumy NPO” is the largest manufacturer of pumping equipment in Ukraine and CIS countries. Manufactured pumping equipment is rather diversified and finds wide application almost in all branches of industry.

Company's history in production of pumps has more than 100 years experience. The first water pumps were manufactured in 1902. There were pumps for sugar plants. In 30th the company mastered the production of liquid-packed ring-type pumps and at the end of 40th — vacuum rotary vane-type pumps. 60th years is the beginning of manufacturing of special chemical pumps made of titanium. In 80th it was actively continuing the mastering of new types of pumping equipment for oil, chemical and other branches of industry.

For stimulation of oil production by method of water flooding of oil beds under high pressure since 1980 PJSC “Sumy NPO” started to produce multi stage centrifugal pumps of U.HC (CNS) type. Presently more than 10 000 of such pumps are under operation in oil industry. These pump units have been supplied not only to CIS countries but also to Iran, Syria, Argentina, Pakistan and other countries. They are in great demand among oil-industry specialists, especially in Western Siberia. For 30-year period of production of U.HC (CNS) pumps designers considerably improved these pumps, mastered new types of this equipment.

The development of industry in 90th determined the mastering of new types of pumping equipment.

We enlarge the range of vacuum liquid-packed ring-type and rotary vane-type pumps, centrifugal pumps for chemical, coal, metallurgical, paper making and other branches of industry and develop new types of pumping equipment.

PJSC “Sumy NPO” becomes the main supplier of special pumping equipment for nuclear power plants.

The range of production includes reactor coolant pump with 3power 8 000 kW and head 20 000 m of coolant per hour

for I circuit of power generating unit and 14 types of pumps of the II circuit (feed water, condensate, circulating pumps). Manufacturing of pumps is carried out in specialized workshops in full compliance with the requirements of Safety regulations for nuclear power energy and subject to strict technical inspection and tests. Total service life of this equipment is not less than 30 years.

Running nuclear power plants in Russia, Ukraine, Armenia, Lithuania, Bulgaria, Finland, Czech Republic, Hungary, Slovakia and China are completed with pump equipment manufactured by Sumy machine-builders.

Directions and results of modernization

1. Improvement of pump rotor bundle for the purpose of gain in economic efficiency, expansion of operating head area, reduction of pump vibration activity.

2. Application of mechanical seals, conforming to API 682 requirements, with introduction of flushing system for products of erosion, corrosion and other suspended particles, or gland seals made of up-to-date packing material "Graphlex".

3. Application of flexible plate coupling instead of gear-type coupling intended for reduction of vibration activity, reduction of axial motor rotor displacement, reduction of fire hazard due to non-availability of oil for lubrication, etc.

4. Gain in life of interstage impellers seals.

5. Installation of axial displacement meter for providing the pump protection against drastic destruction in case of axial rotor displacement due to wear of parts and hydraulic discharging device.

6. Optimization of hydraulic discharging device design intended for reliability improvement and achievement of acceptable leakage level through it.

7. Introduction of protection against overflows in the area of impeller seating on the shaft to prevent the washing of the latter or collection of products of erosion, corrosion and other suspended particles in this area.

8. Improved maintainability, reduced repair cycles, increased time between overhauls.

VK Liquid Ring Compressors59

Technical Data

The example of compressor designation

Designed, depending on flowing part material, for charging of air, inert or aggressive gases, non-soluble in water.

Application: chemical, metallurgical, food industry, machine-building, agriculture and construction.

Main advantage of compressors - easy operation and maintenance. They have no special system for lubrication and oil pumps. All clearances between rotor and static casing are sealed with operating medium. Simplicity of construction, no friction pairs in inner flowing part provide reliability and service life of pump operation.
