Koyu machinery is a hydraulic diaphragm metering pump manufacturer. Today we introduce the structure and characteristics of diaphragm pump. If you don't know much about diaphragm metering pump, you can read this article carefully.
1. structure diagram of mechanical diaphragm metering pump

2. hydraulic diaphragm metering pump structure diagram

The characteristics of diaphragm metering pump:
1) no leakage, especially suitable for transporting dangerous medium.
2) in order to overcome the elastic deformation of diaphragm in the process of suction, the hydraulic diaphragm metering pump needs to consume a certain amount of energy, so the suction performance is worse than that of the plunger metering pump.
3) the clearance volume of the diaphragm metering pump is large, and the volume coefficient is lower because of the deformation of the diaphragm under the force.
4) to ensure the membrane life and improve the volumetric efficiency, the reciprocating frequency of diaphragm metering pump is usually low, n less than or equal to 100 times /min in most cases
5) the radial size of the cylinder head of the diaphragm metering pump is larger. When the flow is too large, the structure is difficult to be arranged, so the flow rate of the diaphragm metering pump is small.
6) under the restriction of the diaphragm strength, the discharge pressure can not be very high.
