From the installation form, there are two categories: vertical and horizontal. According to the number of impellers, it can be divided into two categories: single-stage and multi-stage. Due to the simple structure, low cost, continuous operation and easy cleaning of centrifugal pumps, centrifugal sanitary pumps are widely used in aseptic processes.
Since the impeller is immersed in the medium, and the high-speed rotation of the impeller will generate high shear force, it will affect the shear-sensitive conveying medium.
advantage:
Simple structure, durable and easy to clean on site;
No overpressure due to discharge valve closing;
Can be connected in series to increase the pressure head;
Can be connected in parallel to increase flow.
shortcoming:
Usually do not have self-priming (except self-priming) ability;
Not suitable for applications with viscosity greater than 500cP;
Shear sensitive products should not be handled;
It is not suitable to handle fluids with high gas content;
The head is not constant with the flow change.
