The centrifuges are among the principal types of equipment manufactured by JSC "Sumy Frunze NPO". Their manufacture was started by the Company in 1902. At that time they were as low-speed suspended basket, and of simple design. The basket was driven by bevel pinions. The train of several centrifuges was driven by transmission with common drive of steam-engine.
In the 1930s the Company mastered the production of centrifuges with individual electric drive, and in 1940 the first automatic centrifuge of AG-1800 type was manufactured. In the 1950-1960s four-cascade continuous-action centrifuges for refined sugar production were designed and manufactured. Two-cascade centrifuges of FGP-400, 630, 800 types were supplied for production of copper vitriol, sodium chloride, ammonium sulphate, and for by-product coke plants. The whole range of centrifuges made f titanium was mastered by the Company.
In 1961 the Company's experts developed new design of automated suspended centrifuge for sugar industry with basket capacity of 500 kg per cycle. It was a step forward in national centrifuge engineering. Further development of these machines, many years experience of their manufacture and operation allowed to design new, more powerful and reliable centrifuges of FPN-1250 type with basket capacity of 800 and 1000 kg, as well as to develop fundamentally new design of inertial continuous-action centrifuge of FPI-1321 type. The manufacture of centrifuges for sugar industry covers the larger part of centrifuges supplied by the Company. By the late 1980s their output was increased up to 560 pcs.per year. At present more than 12,000 centrifuges are being operated at sugar-refineries in many CIS countries.
Automatic filtering and settling centrifuges manufactured by JSC "Sumy Frunze NPO" are in operation in chemical, biological, chemical-recovery coke, food and other branches of industry of the CIS (Sumy Chemical Plant, BEREZNIKIAZOT, Tambov Production Enterprise PIGMENT, Sterlitamak Production Enterprise SODA, Ufa Oil Refinery, Volgograd Production Enterprise CHIMPROM, Novo-Neftekamsk Iodine and Bromine Plant, Novosibirsk Tin and Zink Plant, Achinsk Alumina Refinery) and far-abroad countries.
At present JSC "Sumy Frunze NPO" produces nearly all centrifuge types known in the world engineering, including modern heavy-duty automatic centrifuges with continuous cycle, high-speed tubular centrifuges, etc. These centrifuges are completed with modern energy-saving variable speed electric drives, frequency converters and regeneration units manufactured by "Siemens", automatic control systems based on state-of-the-art programmable controllers and other technical means produced by "Schneider Electric".
