Dry-Prime Pump With Vacuum Assist (also referred to as dry mechanical pump) refers to the pump can begin to pump under atmospheric pressure, and can be pumped directly into the atmosphere to the pump chamber without oil or other working media, and the pump pressure and oil-sealed vacuum pump equivalent or close to the mechanical vacuum pump.
The application of dry vacuum pump is extensive, mainly in the following aspects:
1) in the preparation process of polysilicon in low pressure chemical vapor deposition;
2) Semiconductor etching process. Corrosive gases and abrasive particles are often used or generated in these production processes;
3) In addition to some processes that produce particles other than semiconductor processes, it is not expected that particles will be mixed into the pump oil, and it is hoped that particles will be discharged from the pump, then a certain type of dry mechanical vacuum pump can meet the requirements;
4) In the chemical industry, pharmaceutical industry, food industry in the distillation, drying, defoaming, packaging, etc., to prevent pollution caused by organic solvents, suitable for dry vacuum pump;
5) Used as the front pump of the general oil-free clean vacuum system to prevent oil pollution.

1. Diesel-powered, strong power, one-button start, large water output, high water delivery efficiency, suitable for outdoor emergency drainage needs.
2. Short self-priming time, quick water discharge, can operate even in rainy weather.
3. Non-blocking and entanglement-free, equipped with a filter screen, allowing the transportation of larger material particles.
4. The pump body is made of aluminum alloy, compact in size, lightweight, high mobility, easy to use, and safe for transportation and storage.
The self-priming water pump is a hydraulic machine used for water extraction, consisting of a pump body, rotating assembly, assembly, debris cover, and assembled with the inlet pipe, outlet pipe, and screen. When the motor is started, the power drives the rotating assembly, and under the centrifugal force of the impeller, air bubbles move upward, creating suction. The air in the inlet pipe is discharged through the outlet pipe outside the pump body, and the water flows out through the outlet pipe. This water pump has excellent performance, deep suction, and large flow, saving labor and time, making it an excellent water pump in practical society.
Working principle of the self-priming water pump
Self-priming means that when the water pump's suction pipe is filled with air, it utilizes the negative pressure (vacuum) formed during the pump's operation to bring the water pressure up from below the suction port under the action of atmospheric pressure, and then discharges it from the pump's outlet.
