, With the rotor rotation, continuous discharge medium.
Discharge flow is a fixed value.
Reciprocating by crank link, feed the media.
Each stroke pump head discharge flow rate is set.
The stator and the rotor are formed to mesh with each other to form a plurality of sealed cavities. When the rotor rotates, the sealed cavity is pushed and the medium is continuously discharged.
Discharge flow is a fixed value.
Flow rate and speed is proportional to 0 ~ 13m3 /, flow and speed is proportional to 0 ~ 500m3 /, flow and speed is proportional to the concentration of the transmission medium affected.
The higher the viscosity the better, solid content can not be too large.
Concentration.
Suitable for low viscosity and solid content of liquid medium.
Not affected by concentration.
Can transport a variety of concentrations, viscosity and wear changes in the media.
Filler or mechanical seal Not required, packing or mechanical seal Slightly greater than mechanical Diaphragm pump Mechanical General, small Pneumatic Leakage Leakage rate No leakage Leakage rate Small Accuracy
