Tips: Types of metering pumps

1. Plunger metering pump
There are two main types of valve pumps and valveless pumps. The plunger metering pump has been widely used in the petrochemical industry due to its simple structure, high temperature and high pressure resistance and other characteristics. In view of the shortcomings of ordinary plunger pumps for high-viscosity media under high pressure conditions, valveless rotary plunger metering pumps have received more and more attention and are widely used in high-viscosity media such as syrup, chocolate, and petroleum additives. Increase metering. Due to the inability to achieve complete isolation between the metering medium and the lubricant in the pump, plunger metering pumps are subject to many limitations in fluid metering applications that require high contamination resistance.

2. Diaphragm metering pump
The diaphragm metering pump replaces the piston with a specially designed flexible diaphragm, and realizes reciprocating movement under the action of the driving mechanism to complete the suction and discharge process. Due to the isolation of the diaphragm, the isolation between the metering fluid and the driving lubrication mechanism is truly realized in structure. The use of high-tech structural design and the selection of new materials greatly increases the service life of the diaphragm. Diaphragm metering pumps combined with the excellent corrosion resistance of composite materials have become the main pump type in fluid metering applications.
