P-S-P automatic switching system
When the centrifugal pump completes self-priming, the EVP self-priming system will automatically switch to dormant state. When self-priming is required again, EVP will start again;
Dry-run protection system
The pump station has its own dry-run protection system to ensure that the instantaneous suction pump will not burn out the mechanical seal when it runs dry for a long time;
Cooling system
High-pressure cooling water is introduced from the centrifugal pump inspection port into one end of the vacuum pump cooling chamber and flows out quickly from the other end, which can quickly and efficiently cool the vacuum pump, ensure that the vacuum pump runs at a lower temperature, and make the EVP self-priming system have an ultra-long service life;
Easy-to-disassemble structure
The vacuum pump cover on the non-drive side can be easily disassembled for easy inspection of wear;
Non-clogging impeller design
The centrifugal pump impeller is designed with a wide flow channel structure to ensure that solid particles with a diameter of less than 76 mm can easily pass through ;
Self-draining function
The centrifugal pump cover is designed with a special structure with a slag discharge function, which can effectively prevent the mechanical seal spring from being stuck by deposited solid particles, thereby causing sealing failure.
