API OH1 Overhung Type Horizontal Centrifugal Pumps

The TEFFIKO TIHP series of API OH1 overhung type horizontal centrifugal pumps. The components of the centrifugal pumps include packing seals, single-end unbalanced mechanical seals, single-end balanced mechanical seals, double-end unbalanced mechanical seals, and double-end balanced mechanical seals. These sealing components are safe, reliable, and have a long service life.

As important components of the centrifugal pump, the pump body and the pump cover are made of high-quality corrosion-resistant alloys, which can resist highly corrosive media.

The impeller, as a key component of the centrifugal pump, is precisely cast using the wax mold process. It features accurate dimensions, high efficiency, an attractive appearance, and excellent quality.

The coupling, one of the components of the centrifugal pump, is a three-section detachable coupling. It can be specially treated, making maintenance convenient and cost-effective.

Application Fields

● Chemical Production: It is suitable for transporting various corrosive chemical raw materials such as strong acids and alkalis, such as sulfuric acid, nitric acid, and sodium hydroxide solution.

● Petrochemical Industry: In the processes of oil refining and chemical product synthesis, it is used to transport crude oil, refined oil, chemical intermediates, and various additives.

● Fine Chemical Industry: It meets the strict requirements of the fine chemical industry for high - precision, small - flow, and high - pressure transportation. For example, it is used for raw material transportation in the production processes of pharmaceuticals, pesticides, and spices.

● Fertilizer Production: It can be used to transport highly corrosive raw materials such as ammonia water and nitric acid. With its corrosion - resistant pump body and reliable shaft seal, it ensures the stable transportation of raw materials and helps the fertilizer synthesis process operate efficiently.

Main Features

● The TEFFIKO TIHP series of chemical centrifugal pumps strictly adheres to the API 610 standard, ensuring that the product quality and performance reach the international advanced level.

● Pump Body: It is equipped with reinforcing ribs. For CFD (Computational Fluid Dynamics) - calculated fluid mechanics and larger pump bodies, a double - volute structure is adopted, which has small radial forces, a beautiful appearance, and a long service life.

● Sealing Components: The mechanical seal design is conducive to the cooling and circulation of the sealing system, making the seal more reliable.

● It has good temperature and pressure resistance and can operate stably under a pressure of 1.6 MPa.

● Suspension Components: The outer shape is manufactured by precision casting molds, with a beautiful appearance and a high degree of generalization. There are 30, 40, 50, and 55 suspensions, and the suspension components are cross - series universal.

● The coupling is a three - section detachable coupling, which can be made into a direct - connected type according to customer requirements through special treatment. It is convenient for maintenance with low costs.

● It is simple to install, operate, and maintain, easy to learn, and reduces the technical threshold for operators.
