FTP security

In my Application I have my own FTP Server and FTP Client (no SSL for better speed) and assuming I have good method of checking at time of connection if the connections are my own. Is if possible for a hacker  to steal data ?
My programs run on Windows OS over LAN and WAN and I use Delphi.

From an unencrypted FTP connection?  Absolutely.  And since you don't know how many intermediate systems are routing your traffic, or which systems, any one of them could eavesdrop on the connection.  Better to use FTP over SSL.
