Piston pump has the following advantages:
compact structure, maintenance free
oil free,low power consumption, corrosion resistance
high pressure,high flow, low noise
long life and other characteristics

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.

Our company offers multiple component configurations allowing piston pump to be used for either vacuum operation, pressure operation, or alternating vacuum and pressure operations.The innovative, compact design incorporates leading edge technologies that allow it to operate harder, quieter and longer, reliable, highly efficient.

Its flow can deliver up to 2 L/min and 18L/M.

Usually our pump has 4 kinds of voltage:6V, 9V,12V and 24V .

When you choose pump, you can tell me the pump's voltage you need.

We can do it for you.

You can choose pump according to our model.

In addition,it can be mounted in any position.
