Selection guide for high concentrated sulfuric acid pump selection method
Generally, a sulfuric acid solution greater than or equal to 70% is concentrated sulfuric acid,which is widely used in many industries, such as petrochemicals, agriculture, medicine, metal processing, textile industry, etc.
So do you know what kind of pump is suitable for conveying concentrated sulfuric acid?
1. On-site working conditions of concentrated sulfuric acid:
The on-site working conditions that need to be clarified include the concentration of concentrated sulfuric acid, working temperature, whether the medium contains particles, and the flow rate and head that need to be met during the entire work.
2. Pump structure suitable for concentrated sulfuric acid:
The types of pumps that can be used to transport concentrated sulfuric acid include: magnetic pumps, self-priming pumps, centrifugal pumps, and submersible pumps. The specific type should be selected based on the specific gravity of sulfuric acid to use a self-priming pump or a magnetic pump. HUATAO GROUP magnetic pump has a completely leak-proof design without a shaft seal, and the installation environment on site can be used to select horizontal or vertical.
3. Material selection for concentrated sulfuric acid pump:
The materials used for concentrated sulfuric acid pumps can be made of basic plastics, such as PP, PVDF, ETFE (polytetrafluoroethylene), etc. Because concentrated sulfuric acid is highly corrosive, PVDF and ETFE plastic pumps can be selected for concentrations above 80% and temperatures below 90°C.
Specifications for operating corrosion-resistant pumps when transporting sulfuric acid
1) Before operation, check whether the fastening bolts of the motor and base of the concentrated sulfuric acid corrosion-resistant pump are complete and fully buckled.
2) Open the inlet and outlet valves of the concentrated sulfuric acid corrosion-resistant pump, and observe whether the static seals of the pump and valve are leaking, and the dynamic seals have no obvious dripping.
3) Check whether there are signs of dripping in the surrounding environment of the concentrated sulfuric acid corrosion-resistant pump.
4) Wear protective equipment, including goggles, gas masks and masks.
Shutdown and maintenance:
1) When shutting down, first close the inlet valve, then disconnect the power supply, and turn off the outlet valve of the plastic corrosion-resistant pump.
2) Check whether there is leakage at the machine seal.
3) Always pay attention to the water level changes in the suction pool, observe whether the suction port is blocked, and avoid pumping water containing too much sediment. After parking in winter, pay attention to maintenance and antifreeze.
The above is the concentrated sulfuric acid pump selection guide provided by HUATAO GROUP. If above these three steps has been confirmed, it is easily to choose the concentrated sulfuric acid pump. If you are unsure or there is more than one medium, you can consult our technicians at the contact information below to help you choose the appropriate concentrated sulfuric acid pump.
