No need for electricity, with explosion-proof features, capable of delivering flammable and explosive media. No dynamic seal, can rotate dry, and will not cause damage to the pump. No impeller, low shear, not easy to damage material structure. Capable of transporting water, easy to move, flexible and convenient to install, and easy to maintain. Can rotate high viscosity and viscous media. Can rotate strong acids, strong bases, strong organic solvents and other media. It is possible to modify the intake and pressure to adjust the flow rate and range of transportation.
