High viscosity pump advantages: (1) delivery of liquid smooth, pulsation, vibration, low noise. (2) high viscosity pump has a strong self-priming performance. (3) The correct selection of parts materials, can transport a variety of corrosive media, the use of temperature can be 200 ℃. (4) the same internal and external rotor rotation, wear small, long service life. (5) high-viscosity pump speed and flow rate as a linear function, may be appropriate to change the pump to change the flow. (6) High viscosity pump is especially suitable for conveying high viscosity and consistency media.
