1, how to choose the metering pump pressure?

The choice of metering pump generally need to know the rated pressure, rated flow, type (diaphragm or plunger) and over-flow material. Generally speaking, the rated pressure of the metering pump refers to the outlet pressure. It is better to select the rated pressure more than 10% -20% of the actual working pressure when selecting the type, which can not only save resources, reduce the cost, but also improve the actual usage of the metering pump Measurement accuracy.

2, how to choose the metering pump flow?

Metering pump work, usually in the rated flow of 10% -90% of the use of relatively high measurement accuracy, so the choice of rated flow, the general selected flow should be equal to or slightly larger than the flow rate required for the process.

3, how to choose the type of metering pump?

Metering pump according to the different forms of transmission, mainly divided into two types of plunger and diaphragm, plunger metering pump performance is relatively stable, relatively high accuracy, you can transport some of the relatively high viscosity media, diaphragm metering pump in addition to the front Advantages, there are some special advantages: no leakage during operation, can transport special liquids (such as dangerous goods, corrosive liquids, etc.), if you have any difficulties in the selection or questions, please call our company , My company will provide you with free professional selection of programs.

PVC Lead Compound Stabilizer

Compound lead salt heat stabilizer uses a symbiotic reaction technology to mix the three salts, two salts and metal soap in the reaction system with the primary ecological grain size and various lubricants to ensure the full dispersion of the heat stabilizer in the PVC system, while the formation of particles due to co-melt with the lubricant, but also to avoid the poisoning caused by lead dust. The compound lead salt stabilizer includes the heat stabilizer components and lubricant components required for processing, and is called a full-package heat stabilizer. The various components of the compound heat stabilizer can be fully mixed in its production process, which greatly improves the uniformity of mixing and dispersion with the resin.
