It is better to use a sewage lifter with an external pump for the toilet toilet sewage lifter

Drainage is an important part of the renovation of the basement of the villa. So it is particularly important to choose a reliable sewage lifter, so today we will explain the pump, which is one of the most important components of the lifter.

Sewage lifters are divided according to the product structure, and the pumps of sewage lifters on the market are divided into two categories.

External pump: It is to place the submersible sewage pump motor outside the sewage tank, the whole is not in contact with the sewage, only the impeller and volute are in contact with the sewage, and the start and stop of the pump are controlled by the pneumatic liquid level control system.

Built-in pump: The submersible pump motor is installed in a water collection tank, and the start and stop of the pump is controlled by the liquid level control of the float.

Built-in sewage lifter because the submersible pump motor is inside the box, the submersible pump will be immersed in the sewage, need to be installed in the way of buried, the water collection tank will remain more sewage for a long time, the water pump and float controller in the box are together with fecal impurities, followed by the float in a small space, it is easy to be entangled by toilet paper and long fibers, or stuck by impurities, resulting in the pump can not start normally, and finally the sewage overflows; At the same time, because the pump and float level are inside the box, once the failure occurs, the pump and float level gauge need to be taken out in the wastewater containing feces, the operating conditions are very bad, the smell will be emitted indoors, which affects the environment very much, and the after-sales personnel are not willing to operate.

The external sewage lifter adopts the structure of water and electricity separation, the motor and the controller are separated from the water tank, and the sewage in the water collection tank can be discharged to a relatively low water level through the controller, which can basically achieve the working mode of sewage with the go, and the advantage is more obvious in the hot summer. However, the structure of the sewage lifter has higher requirements for the pump, especially the heat dissipation problem, in the face of the frequent start of the pump and the heating motor, the German Zede dares to adopt the external structure, and has a complete heat dissipation solution, can be used in complex environments, and for a long time.

So which one do you prefer, external pump or built-in pump?
