12 volt dc vacuum pump -40kpa electric vacuum pump
Micro pumps for pumping are divided into two categories: gas sampling pumps and micro vacuum pumps. Although they are usually referred to simply as miniature vacuum pumps without distinction, they are different from each other in a technical point of view and should be chosen with special attention.
In short, the gas sampling pump can only carry a small load (i.e., the pump suction end’s resistance can not be too big, but the price is cheap; in the strict sense, the miniature vacuum pump can carry a large load (the suction end allows large resistance, or even completely clogged up, but the price is slightly higher. The resistance of the pump can be measured by means of instrument. Comparing it with the por of maximum allowable resistance of air inlet in the pump's technical parameter, we can know whether the type selection is appropriate or not. It is usually determined by a simple method based on experience. For example, the following conditions are of high load (that is, the pumping end of the pump has greater resistance and can only be selected within the scope of the miniature vacuum pump):
1. At the pumping end of the pump to be connected to a very long pipe, or pipe bending points, severe bending will even block closed, or the pipe has a very small hole (for example, less than φ 2 mm);
2. There are throttle valves, solenoid valves, air path switches, filters and other components on the pipeline;
3. The pump outlet is connected with the closed container, or the container is not airtight but the air intake is small;
4. The pump outlet is connected with the closed container, or the container is not airtight but the air intake is small;
5. The pumping end of the pump is connected to the filter container, which is used to speed up liquid filtration.
12 volt dc vacuum pump's parameter and features
1. High temperature performance, good consistency
2. Oil resistance and easy installation
3. DC brush motor
4. Long life span, low heat.
5. Heavy duty work for 24 hours and Continuous operation
6. The key parts are imported
7. Can work for long hours
12 volt dc vacuum pump's working principle
Working principle: the rotary motion of the motor turn into the swing of connecting rod which makes the diaphragm up and down motion. In the process of the downward movement of the diaphragm, pump cavity will suck medium through the inlet valve; Upward movement of the diaphragm, pump cavity press out media through the outlet valve. Mechanical transmission parts and pump cavity is isolated by diaphragm. Diaphragm pump does not need oil for auxiliary lubricating, in the process of transmission, extraction and compression of medium.
12 volt dc vacuum pump's application
industrial pressure and vacuum applications
Portable analytical instruments
Medical diagnostic equipment
Air quality sampling monitors
Gas or odor leak detectors
12 volt dc vacuum pump's dimension
Outlet:OD 4.3mm, silicone hose suggestion:ID 3mm
Materials:pump body: PC/PPS, diaphragm: EPDM
Because we use imported ball bearing,the pump’s performance is stable and high.
The membrane is made by EPDM and pump's body is made by special PC/PPS which make pump well endurance and strong chemical resistance.
