Use of rotor pumps
Thread Content
Have you used a rotor pump before? Is it good to use? Recommend a good company.
I haven’t worked with them, but I know of a relatively large company that does this. Sino-German joint venture Ningbo Delishi Pump Industry
Back then, there were three major brands of rotary pumps in the world: WAUKESHA, APV, and JOHNSON. Later, all of them were acquired by SPX. Ningbo Delishi was one of the first manufacturers to imitate foreign rotor pumps; the joint venture is a scam, but their products are good. The best rotor pumps are still Vockeroth.
Whether it’s useful or not depends on what you play
There are several rotor pumps manufactured in Zhejiang; in most of these cases, a rubber lining is applied to the rotor, and they are used for transporting granular materials or for cleaning silos. Cam rotor pumps produced in Hebei generally have stainless steel rotors and are used for transporting highly viscous fluids.
Rotary pumps are a general term for gear pumps, screw pumps, vane pumps, cam pumps, and so on. It seems that everyone upstairs was led astray by Baidu Baike; the information there is completely nonsense. The one from Ningbo Delisi can at most be called a cam-type rotor pump.
I am from Ningbo Hengshi Pump Industry, which specializes in the production of rotor pumps. For any inquiries, please contact 15867838769
