PURPOSE

Turbo-driven condensate-feed pump assembly of КПТН type is used in the power plant and intended for supplying feed water from capacitor to steam generator or boiler.

DESIGN

The pump assembly is hermetically sealed, vertical, twin-shaft: feed pump’s high-speed rotor is separated from condensate pump’s speed rotor by means of rotating guide device in the ratio of 6.1. Drive – steam turbine with power capacity of 1000 kW.
