This type of pump is used in process plants for transfer of oil, liquefied hydrocarbon gases and other petroleum products with density not exceeding 1200 kg/m3. The temperature of transferred liquids is -80°C up to +400°C. Viscosity is 2,0 x 10-4m2/c up to 6,0 x 10-4m2 /c. The material for the exposed pump components is defined depending on the temperature and properties of the transferred fluid. Pumps are manufactured in versions Ó, T for different climatic zones and allocation categories 2, 3 and 4 as per GOST 15150-69. The pumps are intended for explosive production process with possible generation of explosive mixtures of gas and vapor with air and related to the explosive category of IIA, IIB to GOST P51330.11-99 and groups T1, T2, T3 and T4 in compliance with GOST P51330.5-99.
Pumps are supplied with stuffing-box or end seals (single, double, tandem-type). Pump units are equipped with explosion-proof electric motors and are supplied on welded frames.
