Types Of Pumps Equipped Liquid Filling Machine

1、 Gear pump
Gear pump is a commonly used pump in liquid filling machines, which drives the flow of liquid through the rotation of gears. Its characteristics are simple structure, small volume, able to withstand high pressure and high temperature, suitable for the transportation of low viscosity liquids, such as edible oil, lubricating oil, etc. However, gear pumps have high noise levels, relatively short service life, and high requirements for liquids.
2、 Screw pump
A screw pump is a type of pump that drives fluid motion by rotating a screw, suitable for liquids with high viscosity and high temperature. Screw pumps are generally divided into two types: single screw pumps and twin-screw pumps, with twin-screw pumps having greater and more stable conveying capacity. The structure of screw pumps is relatively complex and requires regular maintenance.

3、 Centrifugal pump
A centrifugal pump is a type of pump driven by centrifugal force, typically used to transport low viscosity liquids and gases. Its structure is relatively simple and has low noise, but the pressure of the centrifugal pump is unstable, which can easily cause energy waste.
4、 Diaphragm pump
Diaphragm pump is a type of pump that uses diaphragm vibration to drive liquid flow, suitable for transporting various corrosive liquids, high viscosity liquids, and high-temperature liquids. Compared with other pumps, diaphragm pumps have the advantages of strong corrosion resistance, good sealing, and strong self-priming performance of the pump body material. But the cost of diaphragm pumps is relatively high, and maintenance is also difficult.

In summary, there are various types of pumps used in liquid filling machines, and different pumps have different applicable scenarios and advantages and disadvantages. When choosing a pump, one should consider their own needs and actual situation.
