Chemical process pumps offer several key advantages that make them highly versatile and reliable for a wide range of industrial applications. First, these pumps feature three types of impellers: closed, semi-open, and open. This design flexibility allows them to handle various media, including clean liquids, those containing particles, or even fluids with small amounts of gas. Moreover, they are capable of transporting extreme temperature media, such as high-temperature or low-temperature liquids, as well as strong corrosive substances.
Second, the pump body is connected to the bearing housing via an intermediate section. This design enables the use of different materials for the connecting part depending on the working conditions. This helps prevent corrosion damage to the bearing frame when handling aggressive media. Additionally, the intermediate section includes a water-cooled chamber, which circulates cooling water to protect the bearings from high-temperature media.
Third, the sealing system offers multiple options, including packing seals, single or double mechanical seals, and cartridge-type single mechanical seals. These can be selected based on specific application requirements, such as cooling and flushing needs, following API682 standards for optimal performance and reliability.
Fourth, the bearing housing is designed with three cooling methods: air-cooled heat sinks, built-in fans, and water-cooled chambers. Users can choose the most suitable option based on their operating environment. The bearing lubrication system uses an oil ring splash method, where the oil is cooled by the water in the water-cooled chamber. This ensures efficient heat dissipation and keeps the bearings operating at ideal temperatures.
Finally, the pump supports two types of mounting: center support and foot support, depending on the temperature and pressure conditions of the medium being handled. This adaptability makes chemical process pumps a popular choice across various industries, including chemical processing, petrochemicals, and pharmaceuticals.
