Liquid to be pumped:
Service water (except sea water) with pH 6-9,5 and a content of mechanical impurities not exceeding 0,1 % by volume and up to 0,2 mm in size, and also other liquids similar with water in density and chemical activity.
The temperature of the liquid being pumped:
for the electric pumps of 1KM50 and 1KM65 type - from 263 up to 358K (from minus 10 up to +85°C);
for the electric pumps of 1KM80 and 1KM100 - from 263 up to 378K (from minus 10 up to +105°C).
