The fuel oil charge pump НГ 800-250 is designed for delivering fuel oil (a heavy pyrolysis tar) into the high-pressure polyethylene production plants. Electrically driven horizontal single-stage axially split volute casing centrifugal pump with a double entry impeller. The pump rotor is carried by the plain bearings with forced oil lubrication. Shaft sealing: by mechanical seals.
The tower bottoms pump НГ 200-510 is designed for handling tar (asphalt flux removal) in the slow coking process units at the petroleum refineries. Electrically driven horizontal multistage ring-section barrel-insert centrifugal pump. The pump rotor is carried by the pressure oil lubricated plain bearings. Shaft sealing: by mechanical seals.
The pumps НГ 200-510 and НМФ 200-600 are designed for handling tar (asphalt flux removal) in the slow coking process units and other oil products at the temperature of 4000ºC. Designed for handling aqueous solutions of mono- or diethanolamines in the plants for cleaning of natural gas from hydrogen sulphide and carbon dioxide.
