Characteristics of self-priming pump products:

1. Strong sewage discharge capacity: The special impeller anti blocking design ensures that the pump is efficient and unobstructed.

2. Efficient and energy-saving: Adopting a hydraulic model, the efficiency is 3-5% higher than that of a typical self-priming pump.

3. Good self-priming performance: The self-priming height is 1 meter higher than that of a typical self-priming pump, and the self-priming time is shorter.

Product Usage

Self suction pumps are suitable for industries such as chemical, petroleum, mining, papermaking, fiber, pulp, textile, food, power plants, municipal sewage engineering, public facility sewage, and river pond aquaculture.

Types of self-priming pumps:

Self priming pumps can be divided into the following categories based on their operating principles: 1. Gas liquid mixing type (including internal mixing and external mixing); 2. Water ring wheel type; 3. Jet type (including liquid jet and gas jet). The working process of gas-liquid hybrid self-priming pump: Due to the special structure of the self-priming pump body, there is a certain amount of water in the pump body after the pump stops running. After the pump is restarted, due to the rotation of the impeller, the air and water in the suction pipeline are fully mixed and discharged into the air-water separation chamber. The gas in the upper part of the air-water separation chamber overflows, and the water in the lower part returns to the impeller and mixes with the remaining air in the suction pipeline again until all the gas in the pump and suction pipeline is discharged, completing self-priming and normal pumping. The water ring wheel self-priming pump is a combination of a water ring wheel and a water pump impeller in a housing, which uses the water ring wheel to discharge gas and achieve self-priming. After the pump is working normally, the passage between the water ring wheel and the water pump impeller can be cut off through the valve, and the liquid inside the water ring wheel can be drained. Jet type self-priming pump, composed of a centrifugal pump and a jet pump (or injector), relies on an injection device to create a vacuum at the nozzle to achieve suction.

According to the type of matching power machine of the pump, it is divided into electric motor matching self-priming pump and diesel engine matching self-priming pump.

According to the structure and working characteristics of achieving self-priming function, it can be divided into internal sliding type, external sliding type, water ring wheel type, and other types. The transmission methods include direct drive (including inner shaft) and belt drive. Imported diameter of 25-200 millimeters.
