The sanitary lobe pump rotor pump has a constant displacement when the pressure changes, and discharges the liquid by the squeezing action of the rotating rotor, so when the piston presses the liquid, the flow is usually small, which is a kind of rotor pump.

What are the advantages of sanitary lobe pump?
The sanitary lobe pump is one of the most advanced fluid equipment in the world. Its rotor is fully rubber-coated, and the rotor and the shell have a high-precision clearance fit. Compared with gear pumps and screw pumps, sanitary lobe pumps are more abrasive, with strong self-priming and high lift forces. The pumps are reliable, sturdy, energy-saving, and can transport various viscous or particulate-containing media. High efficiency, energy saving, time saving, no need for drainage and irrigation pumps, and can be applied to various complex fluid media.
What is the working principle of sanitary lobe pump?
The sanitary lobe pumps rely on two synchronous counter-rotating rotors to generate suction (vacuum) at the inlet during the rotation, thereby sucking in the material to be transported. The two rotors divide the rotor chamber of sanitary lobe pumps into several small spaces and operate in the order of ABCD; when it runs to position A, only chamber I is filled with medium; when it reaches position B, part of the medium is closed in chamber B leading position C At the time, part of the medium is also enclosed in the A chamber; at the position D. Room A and Room B communicate with Room II, and the medium is transported to the discharge port.
What is the difference between sanitary lobe pump and gear pump screw pump?
1. The internal structure of sanitary lobe pump and screw pump is different. The sanitary lobe pump uses two counter-rotating rotors to change the volume from the feed port to the delivery port from large to small to achieve the purpose of conveying materials. The screw pump uses a spiral screw to rotate at high speed in the rubber stator. , So that the material can be spirally rotated from front to back and finally discharged from the discharge port.
2. The service life of parts of sanitary lobe pump and screw pump is different. Since the parts of sanitary lobe pump are basically zero-wear and have a longer service life, the wear on the flow-through parts mainly comes from the abrasive and corrosive chemical components in the medium; there is friction between the rotor and the stator of the screw pump. Conveyor belt particles easily affect the life of wear parts. The stator bears the stress generated by the eccentrically rotating rotor, which increases the wear between the components. Even if the medium is transported without any particulate matter, the stator of the screw pump will experience a certain amount of wear over time.
