API 610 and ISO 13709 are the world’s most stringent standards for centrifugal pumps in the petroleum and petrochemical industries. These standards mandate rigorous design, materials, testing, and quality requirements that ensure pumps can operate safely under extreme pressure, temperature, and corrosive conditions in refineries, chemical plants, LNG facilities, and offshore platforms. ChemPumps manufactures API 610-certified centrifugal pumps engineered for hydrocarbon service, acid recirculation, cooling loops, and critical process applications where equipment failure is not tolerable. Our portfolio includes horizontal and vertical configurations, with discharge pressures to 16 bar, temperatures to 200°C+, and proven reliability across 30+ countries in Europe, Asia, Africa, and the Americas.
Our API 610 / ISO 13709 pumps are purpose-built to deliver maximum reliability, safety, and efficiency across the world’s most demanding chemical, petrochemical, and refining operations. Designed in full compliance with API 610 and ISO 13709 standards, these pumps ensure long-term performance in high-temperature, high-pressure, and heavy-duty process environments. Whether you need a robust centrifugal pump, a precise process pump, or an advanced API 610 chemical process pump, our engineered product line provides the durability and performance required for continuous operation in mission-critical industrial settings.
Our offering covers the full spectrum of API categories, including the highly reliable API 610 OH2 pump, widely used for chemical services, refinery circulation, and general industrial transfer systems. These single-stage overhung pumps are optimized for stability, hydraulic efficiency, and resistance to aggressive media. For higher pressure or more severe operating conditions, the API 610 BB2 centrifugal pump provides superior mechanical strength with a between-bearings design, ensuring exceptional rotor stability, reduced vibration, and extended service life in continuous heavy-duty applications.
Each API 610 pump is engineered with advanced metallurgy options—high-grade stainless steel, duplex alloys, high-temperature materials, and corrosion-resistant configurations—to handle a wide range of industrial chemicals, hydrocarbons, solvents, and corrosive liquids. These pumps are designed specifically for long MTBF (Mean Time Between Failures), making them ideal for critical production units where unplanned downtime is unacceptable.
For facilities requiring specialized transfer operations, our chemical centrifugal pump and horizontal chemical pump configurations combine hydraulic efficiency with strong corrosion resistance, meeting strict chemical processing standards. These pumps ensure stable flow performance and reduced energy consumption even in challenging environments with fluctuating temperatures and pressures. The design focuses on optimized shaft alignment, improved seal chambers, and enhanced bearing protection to maximize operational reliability.
As industrial operations increasingly demand higher output and uninterrupted reliability, our industrial pump and heavy-duty centrifugal pump solutions deliver exceptional mechanical robustness, superior sealing capability, and resistance to extreme process conditions. These features make them ideal for refineries, fertilizer plants, petrochemical complexes, power generation, offshore platforms, and general industrial processing.
Our product line also includes API 610 / ISO 13709 centrifugal pumps, engineered with precision-machined components, advanced hydraulic profiles, and optimized impeller-volute geometry. The result is smoother flow, minimized vibration, reduced NPSHr, and increased system efficiency. Each unit is fully tested under stringent performance and quality control procedures to ensure compliance with global standards and customer-specific technical requirements.

Standard industrial pumps are not suitable for petroleum and petrochemical service. The API 610 standard exists because failures in refinery and LNG operations can cause fires, explosions, and environmental catastrophe. API 610-certified pumps meet mandatory requirements for:
Non-certified pumps cut costs by eliminating these safeguards, but expose your facility to unplanned shutdowns, safety liability, and regulatory non-compliance. API 610 certification is not optional in refinery and petrochemical environments, it is a legal and operational requirement.
ChemPumps designs and manufactures API 610-certified pumps across five core categories, matched to your specific process duty and installation requirements.

No. API 610 or ISO 13709 certification is a mandatory requirement in petroleum and petrochemical operations for safety, legal liability, and regulatory compliance. Non-certified equipment will fail inspection and may result in facility shutdown, fines, and safety liability. Always specify API 610 certified equipment. Contact our sales team for API 610 pump recommendations.
A hydrostatic test pressurizes the pump casing with water to 1.5× its maximum working pressure, held for a specified time, to verify structural integrity and verify zero leakage. This test reveals casting defects, seal weak points, and assembly errors before the pump enters service. All API 610 pumps must pass hydrostatic testing with documented proof. Request a sample hydrostatic test report.
Our horizontal and vertical API 610 pumps are rated for continuous duty up to 200°C and discharge pressures to 16 bar. Specialty cryogenic and high-temperature designs are available for LNG, thermal recovery, and high-pressure acid recirculation service. Contact our engineering team for custom specifications.
Certified pumps ship with documentation including API Spec Q1 certification, mill certificates for all materials, hydrostatic test reports, and performance curves. Ask your supplier for these documents before purchasing. ChemPumps provides full documentation transparency. Request API 610 certification documents.
