Coal Chemical Industry
Coal processing applications for conveying liquids containing small amounts of solid particles, such as coal slurry.
Environmental & Wastewater
Wastewater treatment for liquids containing gas, foam or particles; seawater desalination and corrosive liquid transfer.
Paper & Sugar Industries
Paper mill pulp and corrosive liquid transfer; sugar factory syrup and related media handling.
Electric & Thermal Engineering
Power station cooling and circulating water; thermal system liquid transportation for heating networks.
Food & Pharmaceutical
Food processing raw materials and pulp; pharmaceutical factory drug and corrosive media transfer.
Other Industrial Applications

FAQ
Frequently Asked Questions
What is an API OH2 self-priming pump?
An API OH2 self-priming pump is an API 610 compliant overhung process pump with integrated self-priming capability. It draws liquid into the pump casing without external vacuum equipment, making it suitable for tank unloading, suction lift and intermittent process duties.
How does a self-priming pump work?
The pump uses an optimized impeller and radial split volute to evacuate air from the suction line and create sufficient vacuum to lift liquid. Once primed, it operates as a standard centrifugal process pump with stable hydraulic performance.
What are the advantages over standard centrifugal pumps?
Self-priming pumps eliminate external priming systems, simplify installation, reduce auxiliary equipment and handle suction lift conditions where standard centrifugal pumps cannot start reliably. They are ideal for tanker unloading, tank drainage and applications with intermittent suction.
Which industries commonly use API self-priming pumps?
Petrochemical plants, refineries, coal chemical processing, environmental protection, wastewater treatment, power stations, food and pharmaceutical production, paper and sugar mills, steel, mining and municipal water supply systems.
What materials are available?
FEIYUE offers metal and non-metal material options including carbon steel, stainless steel, duplex stainless steel and specialty alloys. Material selection depends on medium corrosivity, temperature, pressure and abrasion level.
Can FEIYUE customize the pump?
Yes. FEIYUE can customize materials, sealing systems, hydraulic configurations and auxiliary systems according to your flow rate, head, medium, temperature and operating conditions. See performance specifications or contact our engineers for project support.
