Which submersible pump has good quality?
Thread Content
As the title suggests, since it’s a buried tank, I want to purchase an submersible pump. However, it seems that the quality of such pumps isn’t very good. I was wondering if anyone has used any good submersible pumps and could recommend them. Thank you very much. The media are: vinyl acetate, butyl acrylate, styrene, ammonia water (20%), and formalin solution. The temperature is around 25°, the flow rate required is about 20 m3/h, and the head required is approximately 30 meters.
It depends on the depth underwater in meters; if the shaft is too long, it is not really advisable to use an submersible pump, as it has a high failure rate and is difficult to maintain. For buried tanks, a self-priming pump can also be used if there is sufficient space.

Damage to submersible pumps is mostly caused by impurities in the medium; as long as the impurity content in the medium is low, the pump can generally be used for a long time. KAIQUAN Pumps is a well-known company – check if they have such products available. For reference.
Dalian Acid-Resistant Pump Factory, a professional manufacturer.
For submersible pumps, the axis length is the key factor to consider; I’ve seen ones with an axis length of 5 meters. It’s not necessary to think of Kaiquan whenever talking about pumps – there are so many different types of pumps, and Kaiquan only produces a small portion of them. To be honest, they aren’t very good at manufacturing submersible pumps.
These are personal opinions for reference only. Whether the words are true or not is irrelevant to the topic.
It’s not difficult to choose a manufacturer for this application; there are many companies that can handle it. Confirm how many meters the shaft length needs to be. Contact the manufacturer again to select a model.
The diameter of my tank is 2.5 meters. Do you have any recommended manufacturers?
It is recommended to use self-priming pumps, as they are easy to maintain and have a low failure rate
When using a self-priming pump, the net positive suction head may not be sufficient; for pumping such media with a submersible pump, it is best to choose products from reliable chemical pump manufacturers
The submersible pumps made by Nippon Kikai Hydralic Pump Co. seem to be manufactured in Dalian; our unit has been using them for over a decade with almost no need for repairs.
