Selection of diaphragm pump for plate and frame filter press

First, the shortcomings of the use of diaphragm pump:
1, pressure can not be improved, the pressure of gas source is limited, 6bar reaches the upper limit.
2, noise and pipeline vibration are especially obvious when the air volume is high.
3, compared with the screw pump, the diaphragm life is short and easy to damage.
4, because the flow of diaphragm pumps is usually not too large, most of them are used in small systems.

Second, the advantages of the use of diaphragm pump:
1, low investment, screw pumps need to be able to adjust the flow device, frequency conversion or pressure regulating valve, and the need for supporting pressure sensors;
2. The work is reliable and simple. It can automatically balance the flow with the increase of filtration resistance.
3. The area is small and easy to install. The main products include press box filter press, plate and frame filter press, diaphragm automatic filter press, quick open diaphragm pressure filter and polypropylene filter press. There are dozens of models and hundreds of specifications for 320-2000 types of filter press, the filter area is 2-1000 square meters, and the filtration pressure is 0.4Mpa - 1.6Mpa.
