1, CYZ-A self-priming pumps, with a simple structure, convenient operation, smooth running, easy maintenance, high efficiency, long service life, and have the other pumps do not have the characteristics of self-priming function. Not at the end of pipe valves, pumps work just to ensure that there are quantitative in vivo reservoir of oil can be cited. With a "one-draining, life-long self-priming" function for the oil tanker or ship, they can double pump module So, So good module.

 2, the pump is fine for high-quality materials selected from, the use of carbide mechanical seal sealed, durable, does not require the installation of pipelines out safety valve, inhalation valve at the end of lines, therefore do not need to install a pipeline system to simplify and improve the working conditions.
