Sulzer Shareholder has 5 pct Dresser-Rand Stake

Russian billionaire Viktor Vekselberg's Swiss investment firm Renova Group said on Friday it had a 4.99 percent stake in U.S.-based Dresser-Rand, which might become the object of a takeover battle.

Swiss pump maker Sulzer, in which Renova Group has a 33 percent stake, said this week it was in non-exclusive talks with compressor and turbine maker Dresser-Rand, and media reported on Friday Germany's Siemens was also considering a bid.

Renova said in a statement it did not intend to comment further.
