I'm sorry, but I couldn't find any information about a company called "北方股份isuzu泵车". It seems that "北方股份" may refer to a company in northern China, but there is no information about their involvement in Isuzu pump trucks. Isuzu, on the other hand, is a Japanese automaker known for manufacturing commercial vehicles, including trucks and buses. They may produce pump trucks as part of their product lineup, but without more specific information, it is challenging to provide accurate details.
