Oil & Gas / Petrochemical

Oil, gas, and petrochemical operations cover upstream wellheads to downstream refineries — and every stage carries pumping conditions that demand zero compromise on safety. Volatile hydrocarbons, hazardous chemicals, produced water laden with sand and chlorides, and high-temperature refinery streams all need pumps built and certified for the duty. Weltech's oil, gas, and petrochemical pump range is engineered to international standards with options for hazardous area classification, low-emission seal arrangements, and material specs that handle aggressive media at elevated temperatures and pressures. From wellhead chemical injection to refinery process feed, our pumps deliver the reliability and compliance that hydrocarbon operators depend on. TYPICAL APPLICATIONS • Chemical injection — methanol, corrosion inhibitor, demulsifier dosing at wellhead • Produced water transfer — re-injection and disposal of high-salinity formation water • Refinery process & transfer — crude charge, side-stream pumping, hot oil circuits • Solvent recovery & flare KO drum drainage — recovery of light ends and condensates
