                                   Fish pond sewage discharge: Which is better, submersible pump or self-priming pump?

Submersible pump

Submersible pumps are widely used in fish pond sewage, air conditioning drainage and other fields. It has the following characteristics:

1. Compact structure, small size, easy to install;

2. The noise is small during operation and will not affect the surrounding environment;

3. Ability to strictly control water flow and discharge cleanly;

4. If it needs to operate in water, you need to choose a model with appropriate water depth.

Self-priming pump

The self-priming pump is also a commonly used fish pond sewage device. Its characteristics are as follows:

1. The self-priming pump directly sucks into the water pump and empties itself in the pipeline;

2. The suction lift is large and the water pump can quickly suck in the water;

3. It can withstand the high pressure of cyclic use and is suitable for sewage discharge work in high-rise buildings;

4. Due to its complex structure, regular maintenance is required to maintain excellent operating results.

Comparison between submersible pumps and self-priming pumps

1. Installation environment

Submersible pumps need to run in water, so they are suitable for pure water environments such as fish ponds and aquariums. Self-priming pumps are more suitable for use in sewage wells and dirty water environments.

2. Ease of operation

Both submersible pumps and self-priming pumps can be easily operated and maintained, but submersible pumps need to pay more attention to safety issues because they operate in water.

3. Operation effect

Both are equally effective in terms of water cleanliness, but in terms of operating noise, the submersible pump is very quiet. In contrast, self-priming pumps are noisier when operating.

4. Price

From a price point of view, self-priming pumps are slightly more expensive than submersible pumps, but because they can cope with more complex and harsh sewage environments, their investment value is higher.

Summary

Submersible pumps and self-priming pumps each have their own advantages and need to be selected according to actual usage conditions. If used in a relatively clean pure water well, a submersible pump is a good choice. If you need to deal with more complex and dirty environments, self-priming pumps are more suitable. In addition, when purchasing equipment, you need to pay attention to the applicable scope of the equipment to avoid unnecessary losses.
