API OH2 Overhung Type Horizontal Centrifugal Pumps

The API OH2 overhung type horizontal centrifugal pump is a new series of products designed and developed by TEFFIKO. It features a horizontal, single - stage, single - suction, and radial partial volute structure. It can transport various liquids with high or low temperatures, neutral or corrosive properties, such as inorganic and organic acids like nitric acid, sulfuric acid, hydrochloric acid, and phosphoric acid. It is mainly used in the refining industry, petrochemical industry, coal processing industry, paper and pulp industry, sugar industry, heating and water supply industry, etc.

Application Fields

● Petrochemical Industry

● Refineries: In processes like crude oil distillation, catalytic cracking, and hydro - refining, chemical process pumps are utilized to transfer crude oil, intermediate products, refined oil, and various chemical agents.

● Petrochemical Industry: During the production of basic chemical raw materials such as ethylene and propylene, as well as in polymer production and the synthesis of fine - chemical products, these pumps are employed to convey various reaction raw materials, intermediates, and products. For example, they transport organic compounds like benzene, toluene, and xylene.

● Coal Processing Industry：In processes including coal - to - liquid, coal - to - gas, and coal - to - methanol, these pumps can transport media such as coal slurry, syngas, and methanol.

● Power Industry

● Power Plants: Process pumps are used to transport boiler make - up water, condensate water, and circulating cooling water. They can also be used to convey acid - base solutions and slurries in the desulfurization and denitration processes.

● Paper and Pulp Industry

● Raw Material Conveyance: Pumps are used to transfer the pulp, which is a mixture of papermaking raw materials like wood chips, bamboo chips, and reeds with water, from the storage yard to the cooking or pulping equipment in the pulping workshop, ensuring a stable supply of raw materials.

● Pulp Conveyance: Pumps are used to transport the qualified pulp, which has gone through pulping and screening processes, from the pulp tank to the headbox of the paper machine. This ensures a stable supply of pulp during paper formation and uniform pulp quantity and thickness.
