Sewage pump selection and precautions

The sewage pumps currently on the market are all called non-blocking sewage pumps, so are they really non-blocking? Not necessarily! Frequently, the user's sewage pump is blocked in the sewage pool for a long time and the motor is burned, which makes many users very nervous. What is the principle of the non-blocking sewage pump?
First, we analyze the common debris that the sewage pump is blocked:
(1) Convenient bags in hotels, hotels, and kitchens;
(2) hair and convenience bag in the bathing center;
(3) Woven bags, braided ropes, and plastic bags in the puddles.
(4) fibrous materials such as sanitary napkins in the septic tank;
It can be seen from the above cases that some of the soft fibers are blocked by the sewage pump. The general sewage pump can only discharge some muddy water mixture with sediment or particles, so only the sewage pump that can pulverize the above soft fiber can be called the non-blocking sewage pump. At present, the general sewage pump structure on the market is an S-type flow channel flat-plate impeller and a closed-flow runner impeller, and the sewage discharge effect is relatively good.
Second, we must pay attention to the following points in the selection:
(1) The diameter of the sewage pump should be DN65 or more than DN80 as much as possible.
(2) The impeller is preferably made of a material with higher strength.
(3) The real non-blocking submersible sewage pump is the submersible cutter pump. The MPE series submersible cutter pump provided by Shanghai Jiuru Pump Co., Ltd. completely solves the problem of sewage pump blockage. It has a set of carbide cutters, all through the flow. The road was shattered. Nowadays, many property companies have been plagued by the problem that the sewage pump is blocked and burned out. After using the submersible cutter pump, the original problem can be solved. The submersible cutter pump can solve the problem of clogging of the toilet renovation and the sewage discharge of the clubhouse.
