1）HCX300-3 important plant water pump (300MW nuclear triplex pump in nuclear power plant)

2）HAC600-1A filter back-flush water pump (600MW nuclear triplex pump in nuclear power plant)

2. Product Description

1）The important plant water pump is one of the main equipment applied in the important plant water system in pressurized-water reactor nuclear power plants, and its main functions are listed below：

In conditions of power units normal running or accidental operation, it can convey after heat of the reactor to a final hot well via cooling water, so as to ensure the normal operation and safe shutdown of the reactor.

2）The drum-shaped filter of the safety plant water supply system is mainly used to cut-off the small sundries left by trash rack. In order to ensure units running efficiency, sundries left on the drum-shaped filter must be washed out by the back-flush water pump. Therefore, the back-flush water pump will directly impact the running conditions of the drum-shaped filter, and it is the safety-level equipment.
