Kazakhstan Pavlodar Refinery | API 610 OH2 Process Pumps – Kaiquan

Shanghai Kaiquan Pumps successfully engineered and delivered 53 custom units of API 610 11th Edition Type OH2 heavy-duty process pumps for the landmark Pavlodar Petrochemical Refinery Expansion in Kazakhstan. Supporting Phase 1 of the critical Sulfur Upgrade Project, this deployment solidifies Kaiquan’s engineering excellence in international downstream refining assets.

Conquering Severe Operational & Environmental Challenges

Operating conditions within the sulfur processing facility presented complex engineering hurdles. The pumps required continuous handling of highly corrosive and volatile media under extreme thermal conditions and severe pipeline strain. To maintain zero-leakage reliability, withstand heavy nozzle loads, and adhere to a strict delivery timeline, Kaiquan’s petrochemical team customized single-stage, centerline-mounted, overhung OH2 process pumps designed to absorb high thermal expansion without shaft misalignment.

End-to-End Field Commissioning & Technical Value

Beyond precision manufacturing, Kaiquan deployed specialized field engineers to the Pavlodar jobsite to ensure seamless integration. The on-site team provided comprehensive installation verification, dynamic alignment inspection, and dry-run commissioning support. By combining robust API 610 compliance with dedicated lifecycle services, Kaiquan delivered uninterrupted fluid displacement, helping Kazakhstan modernize its energy infrastructure while meeting stringent environmental sulfur emissions regulations.
