type 12HA
12 - minimum allowable internal diameter of casing 300 mm (reduced by 25 times and rounded to a whole number);
H - oil;
A - artesian;
The unit consists of: centrifugal multistage artesian type 12NA centrifugal pump with mechanical seal and electric motor.
It is designed for application in chemical, oil refining, fuel and energy and other industries for pumping (pumping out) from casing strings (collection tanks, wells, reinforced concrete reservoirs, etc.) of process liquids (water, oil, oil products, oil-containing effluents, etc.).
