Background
Petrochemical pumps are pumps used in petrochemical industry, and most of the liquid to be transported is flammable, and most of the temperature and pressure conditions are severe, so that higher or highest-level pumps are required. The pump body comprises a water suction chamber and a water pressing chamber. The inlet of the water suction chamber and the outlet of the water pressing chamber are respectively provided with a water pump inlet flange and an outlet flange which are used for connecting a water inlet pipe and a water outlet pipe. The suction chamber is typically a section of tapered short tube or isopipe which functions to direct the water flow into the impeller and provide the desired flow pattern to the impeller. The pumping chamber serves to collect the liquid exiting the impeller and direct the liquid flow to the outlet. The appearance of the pumping chamber is similar to a snail shell, commonly called a volute, and the impeller is wrapped in the volute. The common petrochemical transportation pump, the sealing ring of the pump body wall and the connecting pipe is not corrosion-resistant and high-temperature resistant, is easy to corrode and damage after long-term use, has poor sealing effect and has shorter service life.
