Product Features/Benefits
High efficiency and energy saving: It adopts an optimized hydraulic model, which is 3-5% more efficient than ordinary self-priming pumps, with a maximum flow rate of 20m³/h, a head of up to 80 meters, and low energy consumption.
Good self-priming performance: The self-priming height is 4.5-6 meters, the self-priming time is as short as 11 seconds, the gas-liquid mixing and separation speed is fast, and it can adapt to frequent start-stop or complex suction environments.
Reliable construction: Anti-blocking impeller designs can handle liquids containing particles, mechanical seals prevent leaks, and some models are equipped with stainless steel materials for corrosion resistance.
Convenient maintenance: The modular design simplifies disassembly and assembly, requires no bottom valve to reduce plumbing costs, bearings and sealing rings are easily replaced, and support diesel or motor twin drives.
