We need a pump that can be used for both acid and alkali removal; if anyone has any good recommendations, please share them
Thread Content
1. The acid is sulfuric acid (concentration 30%)； The base is sodium hydroxide (concentration 30%). 2. A pump that can be used for both purposes is required, one that can discharge both acid and base ； Are there any other things to note regarding this? Do I need to wash the water pump with clean water after removing the acid? What type of mechanical seal is needed for this, and are there any good brands? Please recommend some.
Plastic magnetic pumps are cost-effective. Rinsing is necessary.

It’s important to use a proper configuration, otherwise leaks or spills will occur, which is problematic. The friction surfaces of the seals used in alkaline environments need to be replaced. We are using discharge pumps made by Anhui Jiangnan.
Could you recommend any good manufacturers?
For magnetic pump liners, Tai warehouse Magnetic Pump Factory is recommended
Why does everyone recommend magnetic pump? A regular centrifugal pump would be sufficient, right? Magnetic pump prices are high, and the magnetic magnets in magnetic pumps manufactured by small companies tend to lose their magnetism, resulting in high maintenance costs later on.
I also do not recommend using a pump with two functions – one for acid and one for alkali – as switching valves is required. If employees make mistakes or the valves leak, it could lead to accidents, and the losses resulting from that would be much greater than the cost of a single pump. The cost of a centrifugal pump is around 10,000 yuan

The requirements aren’t high; an ordinary centrifugal pump made of PTFE can be used, diaphragm pumps are also quite effective, while magnetic pumps aren’t necessary. It’s better to buy two ordinary centrifugal pumps rather than a magnetic pump
It is best to use a dedicated pump, as serious accidents can occur if mistakes are made during operation. If purchasing a pump is really not desired, the location of the storage tank can be lowered, and a higher unloading platform can be built to allow discharge directly into the tank
