Pump D 200-450 and electric pump units based on it

D 200-450 type double-entry centrifugal pumps and electric pump units based on them are designed for pumping:
1) Water and non-toxic liquids having viscosity and chemical activity properties similar to water with density up to 1100kg/m3, viscosity up to 60x10-6 m2/s (60cSt), temperature from 233K to 378K (from minus 40 to plus 105°C) and containing solid inclusions by mass not more than 0,2%, size not more than 0,2mm and microhardness not more than 6,5 GPa (650kgf/mm2).
2) Oil and oil products with viscosity up to 100x10-6 m2/s (100cSt), with temperature from 233K to 378K (minus 40 to plus 105°C), containing no more than 0.2% solid inclusions by weight, size not more than 4mm and microhardness not more than 6.5 GPa (650kgf/mm2).
3) Sea water, formation water and other chemically active liquids with hydrogen indicator pH=1...11 and the content of mechanical impurities by weight up to 0.2%, size not more than 0.2mm and microhardness not more than 6.5 GPa (650kgf/mm2), temperature from 233K to 378K (from minus 40 to...).
