VERTICAL ELECTRIC PUMP UNITS OF NVN TYPE FOR PETROLEUM PRODUCTS PUMPING
Application
Vertical oil centrifugal electric pump units of NVN type are intended for pumping of oil from nonpressure reservoirs, wells, and other oil dumping, formation water, oil emulsion collection reservoirs and similar mediums, and also for supply it into suction delivery pipe of oil-transfer station.
Moreover, oil pumps of NVN type can be used for pumping of aggressive fluids (for example, fluids with high hydrogen sulphide content, acid reservoir water).
These units are intended for exploitation in explosive regions of В1а, В1б, В1г type, where is possible by the operation conditions mixtures formation with air which are related to IIА and IIВ category and explosion safety groups Т1, Т2, Т3 and Т4 under the State Standard 12.1.011-78.
