The given environment: are intended for pumping polluted, including drainage, ground waters from ditches, pits, collections on the under construction or operating objects of the industry, construction, municipal services with the temperature up to 35 °C (usual execution) and with the temperature up to 60 °C (execution of T), rn from 5 to 10, containing mechanical impurity (sand, cement, clay) mass concentration to 10% with particles up to 5 mm in size.
Monoblock, submersible, figurative. Electric pumps are installed vertically on a bottom of ditches or trenches.
In explosion-proof execution (Ekh) allow availability of impurity of crude oil to 10% on weight (sulfurs to 3% in not free state and paraffin to 7%).Symbol: The GNOME 40-25T (In), where
— for dirty water; N — the pump; About — one-stage; M — monoblock;
40 — giving of m3/hour;
25 — a pressure (m) in the nominal mode.
* the marked T, electric pumps in temperature condition to +60 °C,
** marked In, are intended for pumping out of the polluted waters with the content of oil products (explosion-proof).
