Advantages And Disadvantages Of Sanitary Rotary Lobe Pumps

Sanitary Rotary Lobe Pump Before working, the pump body and the water inlet pipe must be filled with water to form a vacuum state. When the impeller rotates quickly, the blades cause the water to rotate quickly. The rotating water flies out of the impeller under the action of centrifugal force. After the water in the pump is thrown out, a vacuum area is formed in the center of the impeller.

Advantages:
1. Small size and small footprint.
2. Simple structure, few parts, easy to maintain.
3. Stable flow and pressure, small vibration when the pump is running normally.
Disadvantages:
1. When operating at a small flow rate below the rated flow rate, the pump efficiency is low.
2. Suitable for conveying various liquids with low viscosity. The viscosity of the liquid has a greater impact on the performance of the pump.
3. Poor self-priming ability and easy to empty. If the dynamic liquid level of the pumped liquid is below the center line of the pump, it must be filled or emptied before starting the pump, otherwise the centrifugal pump will not work properly.
Although the sanitary rotary cam pump can now meet the basic use requirements, it should also be seen that it is insufficient and needs to increase research and development efforts to ensure that it can be more efficient, safe and fast during the conveying process.
