June 8 (Reuters) - India's Bharat Petroleum Corporation will shut a 120,000 barrel per day crude unit and some secondary units at its Mumbai refinery for maintenance in November, an industry source said on Monday.

The state-run refiner initially planned to shut the units at the 200,000-bpd Mumbai refinery in western India in April, a company spokesperson said in an email response.

Earlier, an industry source had said that the three to four week maintenance shutdown of units would happen in September-October.

Indian refiners have delayed their refinery maintenance plans to meet local fuel demand, a government official said previously.
