Petrochemical refineries and downstream chemical plants process crude oil and synthetic feedstocks into fuels, lubricants, plastics, and specialty chemicals through complex multi-stage operations. Each stage requires pumps engineered for high pressure, elevated temperature, and chemical compatibility with hydrocarbons, sulfuric acid, and specialty process media. ChemPumps manufactures petrochemical industrial pumps engineered for refinery alkylation units, crude oil processing, acid recirculation, cooling loops, and high-pressure synthesis reactors. Our API 610-certified and corrosion-resistant pump designs are proven across major refineries in the Middle East, Asia, and Africa, handling volumes from 50 m³/h to 500+ m³/h at pressures to 16 bar and temperatures to 200°C+.
Petrochemical refinery operations demand pumps engineered for multiple simultaneous challenges:
High Operating Pressure – Crude distillation, reforming, and alkylation units operate at 5–16 bar continuous discharge pressure. Pump bearing frames and mechanical seals must tolerate sustained high pressure without failure.
Elevated Temperature – Process streams reach 100–200°C, creating thermal stress on seals, lubricants, and bearing materials. Thermal management is essential to prevent seal degradation and bearing failure.
Corrosive Media – Refinery processes include sulfuric acid (alkylation), hydrofluoric acid (alkylation), and mixed hydrocarbon-acid streams that require specialized material selection and seal systems.
API 610 Compliance – Refineries and petrochemical plants require API 610 (or ISO 13709 equivalent) certification for all critical pumps, mandating rigorous design, testing, and quality documentation.
Continuous 24/7 Operation – Refineries operate around-the-clock, with unplanned downtime costing hundreds of thousands of dollars per day. Equipment must be highly reliable and support rapid maintenance.
Standard industrial pumps are not suitable for petrochemical refinery duty. API 610-certified designs with thermal management and specialized sealing systems are mandatory.
ChemPumps offers six specialized pump types engineered for refinery and petrochemical operations.
Horizontal chemical pumps in API 610 certification are the standard workhorse of petrochemical refineries. Horizontal mounting enables ease of installation and maintenance. Rated for continuous duty to 200°C, pressures to 16 bar, and compatible with hydrocarbon, acid, and mixed media. Single or dual mechanical seals available. Browse API 610 horizontal refinery pumps →
Alkylation units and high-pressure synthesis reactors require pumps rated for discharge pressures exceeding standard centrifugal limits. Our heavy-duty centrifugal pump series delivers multi-stage designs rated to 16+ bar for sustained high-pressure operation. Browse high-pressure petrochemical pumps →
Refinery alkylation units use sulfuric acid or hydrofluoric acid catalysts requiring specialized pumps. Our sulfuric acid pump and acid resistant pump designs handle continuous acid recirculation, acid cooling, and acid recovery with specialized corrosion-resistant materials (B-2 casing + B-11/B-12 Lewmet shafts). Browse alkylation acid pumps →
Petrochemical processes often involve mixed hydrocarbon-acid streams and specialty chemical feeds requiring maximum corrosion protection. Our corrosion resistant pumps use high-alloyed materials for extended service life in aggressive media. Browse corrosion-resistant petrochemical pumps →
General-purpose chemical centrifugal pumps handle broad refinery applications: crude oil circulation, feed preheating, product cooling, and inter-unit transfer. Hydraulically optimized for efficiency and thermal management. Browse chemical centrifugal pumps →
For sump recirculation, tank-mounted duty, and emergency cooling, our vertical turbine pumps maintain full API 610 design rigor with long-shaft stability and robust discharge. Ideal for emergency cooling loops and tank-based transfer. Browse vertical petrochemical pumps →
Refinery operations demand material strategies matched to hydrocarbon type, acid content, and temperature:
| Service | Medium | Temperature | Pressure | Material System | Service Life |
| Hydrocarbon transfer | Crude oil, light fractions | 40–100°C | 5–10 bar | Ductile iron | 5–7 years |
| Sulfuric acid alkylation | 98% H₂SO₄ acid catalyst | 20–40°C | 5–8 bar | B-2 casing + B-11/B-12 shaft | 5–7 years |
| Hydrofluoric acid alkylation | HF acid catalyst | 20–30°C | 5–8 bar | Special corrosion-resistant alloys | Contact for specs |
| Cooling loop circulation | Hydrocarbon-water blend | 40–80°C | 8–12 bar | Alloy ductile iron | 3–5 years |
| High-temperature synthetic | Mixed hydrocarbons | 100–200°C | 10–16 bar | Heat-resistant alloy, thermal relief | 3–5 years |
Crude oil distillation units (CDU) process crude at scale, requiring multiple large-capacity pumps for crude feed, overheads, sidestreams, and bottoms.

API 610 pumps must pass hydrostatic testing, material documentation, vibration analysis, and seal integrity testing before shipment. Non-API 610 pumps skip these safeguards to cut costs, but expose refineries to unplanned shutdowns and safety liability. API 610 certification is mandatory in all petroleum industry operations. View our API 610 certification documentation.
Yes. Our sulfuric acid pumps are engineered specifically for sulfuric acid alkylation duty, using B-2 casing with B-11/B-12 Lewmet shaft sleeves. At 20–40°C, corrosion rates are minimal (<0.02 mm/year), delivering 5–7 year service life. Request alkylation acid pump specifications.
Alkylation reactors typically operate at 5–8 bar discharge pressure. High-pressure synthesis reactors can reach 50–100 bar. Our horizontal chemical pumps handle standard refinery pressure (5–10 bar), while heavy-duty centrifugal pumps deliver multi-stage designs for high-pressure applications. Request pressure rating for your refinery process.
Always request API 610 certification documentation from your supplier before purchase. This includes hydrostatic test reports, material mill certificates, and API Spec Q1 quality certification. ChemPumps provides complete documentation transparency on every order. Request API 610 compliance documentation.
API 610 pumps require seal inspection every 6–12 months, bearing lubrication every 3 months during continuous operation, and planned overhauls every 2–4 years. Exact intervals depend on operating temperature, pressure, and media type. We provide detailed maintenance schedules for each refinery application. Request a refinery pump maintenance schedule.
