What types of pumps are commonly used in sewage treatment?

The types and models of sewage pumps are divided into swimming sewage pumps, long bucket submersible sewage pumps, pipeline sewage pumps or self-priming sewage pumps according to working conditions and installation methods. Submerged sewage is divided into sewage pump with stirring function and sewage pump with cutting function.

I. Overview of submersible sewage pump models and categories

WQ sewage submersible pump

1 and WQ submersible sewage pump

Submerged sewage pump is mainly designed to meet the needs of users who don't want to build a pump room. Small submersible sewage pump can pump water only by connecting the pipeline to the submersible sewage pump and turning on the submersible sewage power supply. It is suitable for conveying all kinds of sewage containing particulate impurities.

2. Submersible sewage pump with automatic stirring function

If there is a lot of sediment, it is best to choose an automatic stirring sewage pump, which can stir up the sediment around the pump and then transport it away, thus improving the sewage discharge capacity of the submersible sewage pump. For example, this series is used to transport waste water from construction sites.

The product is particularly obvious. There is water in the construction site, and the bottom of the pool contains a lot of silt and sediment. It is difficult to clean the sewage at the bottom of the pool without stirring the pump. Note: If the sludge content is large, it is recommended to use the residual sludge pump.

3. Submersible sewage pump with cutting function

The other is a sewage pump product with cutting function, which replaces the shortcoming that the general submersible sewage pump is easy to block when conveying the medium containing gloves in septic tanks or sewage, and the submersible pump cutting pump can completely put all kinds of

Gloves and cloth strips can be chopped and transported away, so when the conveyed medium contains various fibers, it is best to choose the submersible cutting pump instead of the ordinary sewage pump model.

Three. Overview of models and types of pipeline sewage pumps

Pipeline sewage pump is mainly a non-blocking sewage pump product installed on the ground. In fact, the model parameters of pipeline sewage pump are almost the same as those of submersible sewage pump. This series of products is suitable for the working condition that the liquid level is higher than the pump.

If the liquid level is lower than the pump, we suggest that zW self-priming sewage pump is more suitable. Please refer to the model parameters of submersible sewage pump above for the model parameters of pipeline sewage pump.

Four. Overview of models and types of self-priming sewage pumps

Self-priming sewage pump mainly adapts to and needs to install the pump on the ground and in places with relatively low liquid level, such as sewage treatment and discharge in factories. Usually, sewage is collected in a pool lower than the ground.

If you are worried about the trouble of maintenance after using submersible sewage pump and don't want to choose submersible sewage pump, then the more suitable pump is self-priming sewage pump, which is divided into self-priming sewage pump with coupling according to its structural form.

Pump and direct-connected self-priming sewage pump products, the model parameters of the two sewage pumps are the same, the difference is that the direct-connected sewage pump occupies a relatively small area.
