1. Simple and compact structure, easy to use and maintain.
2. It has good self-priming, so no need to pour liquid before starting the pump.
3. Lubrication is achieved automatically by the conveyed liquid, so there is no need to add lubricating fluid during daily work.
4. The use of elastic coupling to transmit power can compensate for the slight deviation caused by installation. When the pump is subjected to inevitable hydraulic shocks, it can play a good buffering effect.
