API OH4 Overhung Type Horizontal Centrifugal Pumps

The TEFFIKO THWP series of API OH4 overhung type horizontal centrifugal pumps features excellent craftsmanship. The horizontal structure gives it a low center of gravity and uniform stress distribution. The pump shaft is connected and positioned precisely, resulting in minimal vibration, strong stability during operation, and convenient maintenance. Its hydraulic flow - through components adopt an advanced model, with an efficiency 5 - 8% higher than that of ordinary pumps, which can reduce enterprise costs. The pump body is made by precision casting, with both excellent internal structure and appearance.

Application Areas

The THWP overhung type horizontal centrifugal pump is highly suitable for transporting chemically corrosive liquids (either containing no solid particles or a small amount of solid particles), and the viscosity of the transported medium is similar to that of water.

● Chemical Industry: It is used to transport various corrosive fluids during the chemical production process.

● Food Industry: It is responsible for transporting fluid raw materials during the food processing process.

● Brewing Industry: It is used to transport raw materials and fermentation broth during the brewing process.

● Refining Industry: It undertakes the transportation of crude oil and refined oil products.

● Pharmaceutical Industry: It is responsible for transporting various liquids required for drug production.

● Paper - making Industry: It transports pulp, white water, and chemical additives.

● Metallurgical Industry: It transports metallurgical liquids, flushing water, and other related liquids.

● Power Industry: It is used to transport boiler make - up water and cooling circulating water.

● Environmental Protection Industry: It transports sewage, sludge during sewage treatment, and absorption liquids for waste gas treatment.
