VK-2G and VK-VK-VK-1G and electrical units based on them are designed to pump neutral, slightly aggressive, harmful and explosive liquids with kinematic viscosity up to 36 · 10 -6 m 2 /s (36 SO), a temperature of -40 to +85 ° C, with the content of solid inclusions of not more than 0.01% by weight and size N e more than 0.05 mm, in which the materials of the flowing part do not allow the linear speed of continuous corrosion of more than 0.1 mm/year GOST 9.908–85.
VK-2G pumps and VK-1G < /Strong> are allowed to work in explosive industries, in which mixtures of gas and air are possible to form a category IIA, IIV and explosion hazard T1, T3, T4 explosion. According to GOST P51330.19.
