1. Inhalation
When the pump body starts to work under water. With the opening of the inlet valve, mud, sand, small stones and other materials will quickly enter the pump body under the action of gravity and head pressure. The flow rate of the material into the pump changes with the change of water depth. When the water depth is within 7 meters (reference value), additional vacuum equipment is required to ensure the material suction flow rate.
2. Discharge materials
The material in the pump body is continuously squeezed by compressed air, and the pump body is discharged from the discharge pipe.
3. Exhaust decompression
When the material in the pump body is exhausted, the discharge valve closes automatically, and the exhaust valve opens at the same time, the compressed air is discharged from the pump body, and the next working cycle is continued.
