VZP series pumps are non sealing automatic control self-priming vertical cetnrifugal pumps, with the feartures of high efficiency, short self-priming time, easy maintenance etc, especially suitable for the site condition that requests frequent starting.
1. Hefficiency, lower NPSHr, Less vibration. Using the advanced hydraulic model of abroad, the efficiency has improved 10-15%.
2. Shorten self-priming time and Increase self-priming height.
3. Using a multi-blade expanded flow runner to accelerate gas-liquid separation, the self-priming time cuts half.
4. Mechanical seal for clear water, and auxiliary impeller sealing for sewage.
