Petrochemical Pump

A petrochemical pump refers to a pump used in the petrochemical industry. Since almost all the transported liquids are flammable, and most of the temperature and pressure conditions are very harsh, higher or highest-level pumps are required.

a. For petrochemical pumps that transport flammable, explosive, toxic, or precious media, reliable shaft seals or leak-free pumps are required, such as canned pumps, magnetic drive pumps, and pneumatic diaphragm pumps.

b. For petrochemical pumps that transport corrosive media, corrosion-resistant materials are required for flow parts.

c. For petrochemical pumps that transport medium containing solid particles, wear-resistant materials are required for the flow parts, and if necessary, the shaft seal should be flushed with clean liquid.

 

Petrochemical Pump Installation Requirements

a. For petrochemical pumps installed in the presence of corrosive gases, measures to prevent atmospheric corrosion are required.

b. For petrochemical pumps installed in the outdoor ambient temperature below 20 ℃, it is required to consider the cold and brittle phenomenon of the pump, and use low-temperature resistant materials.

c. For petrochemical pumps installed in explosive areas, explosion-proof motors should be used according to the level of the explosive area.

d. For factories that require an annual overhaul, the continuous operation cycle of the pump should generally not be less than 8000h. In order to meet the requirements of a three-year overhaul, the continuous operation cycle of pumps for petroleum, petrochemical and natural gas industries is at least three years.

e. The design life of petrochemical pumps is generally at least 10 years. Centrifugal pumps for the petroleum, petrochemical, and gas industries are designed to have a life of at least 20 years.

f. The design, manufacture, and inspection of petrochemical pumps shall comply with relevant standards and specifications.

g. The pump factory should ensure the performance of the pump within the range of power supply voltage and frequency variation.
