How do you melt metering pump understand it

How do you understand the melt metering pump it? And we introduced today, in fact, melt metering pump is designed for transporting liquid metering pumps. Majority melt metering pump piston and the diaphragm are used the structure of the gear pump structure is also useful because they can be kept constant and the discharge flow rate independent of pressure. 

Measurement accuracy is the melt flow metering pump reproducibility accuracy is usually calculated according to the maximum flow rate. Can be adjusted within the range of the general accuracy of the metering pump metering ± 1%. The main factors affecting measurement accuracy is sealing and packing plunger suction and discharge valves work perfection. Overall advantages of the melt metering pump is no leakage, the leakage is particularly suited to the occasion is not allowed, can be accomplished using a melt metering pump delivery measurement and regulation of three kinds of functions, thereby simplifying the production process, automated and semi-automated, and improve product quality.
