◆ No need for irrigation and diversion, suction up to 7m;
◆ Smooth flow, good passing performance, allowing the maximum particle diameter to reach 10mm;
◆ When pumping mud and impurities, there is little wear on the pump;
◆ Head and flow can be adjusted steplessly by opening the air valve;
◆ The pumping medium is completely separated from the working medium, and the conveying medium will not leak outward;
◆ Can work in the medium;
◆ It can transport relatively viscous liquid (viscosity below 10,000 centipoise);
◆ The pump does not need to be lubricated with oil, even if it is idling, it has no effect on the pump.
