What Are The Types Of Sewage Pumps

May 26, 2025

The types of sewage pumps are basically the following, and other sewage pump series with special requirements can be customized according to user requirements.

1. Vertical unobstructed sewage pump: The main feature of a vertical sewage pump is that the inlet is located at the bottom and the outlet is located at the top, and the direction of the inlet and outlet can be adjusted freely. It is mainly suitable for places with limited installation space, and can be installed with a bottom valve directly on the surface of the water tank at the suction port under the water tank. The types of vertical sewage pumps can be divided into submerged long shaft type, vertical land type, or submersible sewage pumps, which can also be called vertical sewage pumps.

2. Horizontal unobstructed sewage pump: The types of horizontal sewage pumps can be divided into two types: direct connected and shaft connected, both with the same structural and performance parameters. The main feature of direct connected horizontal sewage pumps is that the impeller is located on the motor shaft, reducing the installation space of shaft connected ones, and the noise is lower than that of shaft connected horizontal sewage pumps.

3. Pipeline type unobstructed sewage pump: The main feature of pipeline sewage pump is similar to that of vertical centrifugal pump, which adopts a left in and right out method, and the inlet and outlet are on the same horizontal line. It mainly plays a role in boosting and transporting various media similar to sewage containing particles. The types of pipeline sewage pumps are only based on materials such as cast iron, stainless steel, ball milled cast iron, duplex stainless steel, etc.

4. Submersible unobstructed sewage pump: Submersible sewage pumps are mainly pump products that must be submerged in water, mainly suitable for portable and mobile working conditions and places without land installation space. They also eliminate the advantages of building pump rooms. The only disadvantage is that the entire motor is submerged in liquid, and currently submersible sewage pumps cannot transport flammable and explosive liquids. The types of submersible sewage pumps are mainly divided into cutting type, stirring type, and stirring cutting type.

5. Self suction unobstructed sewage pump: The main feature of a self-priming sewage pump is that it is installed on land and has a self-priming capacity of about 6 meters. The highest configuration of a self-priming pump without water filling can reach about 8-10 meters. The advantage of self-priming sewage pumps compared to submersible sewage pumps is that they are easy to maintain and will not burn out the motor due to mechanical seal leakage like submersible sewage pumps. There are two types of self-priming sewage pumps: direct connection and shaft connection.

Before choosing a submersible sewage pump, it is important to understand the purpose of the pump in order to select the appropriate submersible sewage pump product. Below, we will share with you the functions of submersible sewage pumps and their uses for reference and selection:

The main function of a submersible sewage pump is to lift water from a pool or river to higher and farther places.

There are many other functions of submersible sewage pumps, such as being used in various aquaculture industries in farms, as well as for pumping water from fish ponds to clean pond silt, or as oxygenation for fish ponds, and for pumping human and animal manure and urine from septic tanks. It is recommended to use submersible cutting pumps for septic tanks, which are more suitable.

The main use of submersible sewage pumps is for collecting sewage and water in engineering projects, such as various construction sites, construction drainage of various engineering foundations, municipal flood prevention and control, and can also be used to pump well water or tap water.

The use of submersible sewage pumps can also be used for sewage discharge in underground basements, subway stations, and other tunnels under various high-rise buildings.

The submersible sewage pump can also be used as one of the specialized equipment for sewage treatment for small and medium-sized enterprises, and can also serve as a booster for transporting circulating water in factory assembly lines. The submersible sewage pump belongs to the series of sewage pump products.

The submersible sewage pump made of stainless steel material can also transport various corrosive liquids and food grade liquids. Stainless steel submersible pump products can also be used.
