Characteristics
1. The structure is simple and easy for disassembly and maintenance, 2. smooth operation, small vibration and low noise, 3. it can deliver high concentration and high viscosity (less than 10000 PaS) suspended slurry, 4. the drilling fluid flow is stable, no overcurrent, pulsation and stirred, shear slurry phenomena, 5. the discharge pressure has nothing to do with the speed, low flow can also maintain a high discharge pressure, 6. displacement is proportional to the speed, by shifting mechanism or motor, one can adjust the displacement, 7. it has high self-absorption ability, and can suck liquid directly without bottom valve.
