The type of ECN is designed to ensure water circulation in boilers of various types on TPPs and on power units with steam -gas installations.
The EN type is used to pump technical water in auxiliary systems of TPP. The flow parts of the units of this type are made of bronze, resistant to sea water.
The Tsen 200-35 unit is installed in the heat utilization circuit in the technological process for the manufacture of polyethylene products. It is a centrifugal, horizontal, sectional, four -speed pump.
The pumping unit of the ECNA 2890-26 is used to pump condensate in the networks of the thermal geothermal power plant. Given the increased aggressiveness of the pumped environment, in the manufacture of the main parts, stainless steel is 08x22N6T.
