Q: What is the disadvantage of progressive cavity pump?

They PC and screw pumps both have little or no pulsation. The disadvantage of both progressive cavity dosing pumps and screw pumps is that they can not be run dry or they will be damaged. They also can not pump against a closed discharge or they will be damaged.

Q: What is <strong>progressive cavity pump working</strong> principle？

The progressive cavity pumps , also known as a helical rotor pump or a single screw pump, operates based on the principle of positive displacement. It consists of a helical rotor that rotates within a stator with a similar helical profile. As the rotor turns, it creates cavities that move fluid along the axis of the pump from the suction port to the discharge port. The tight fit between the rotor and stator allows for a continuous flow of fluid without any slipping or pulsation. This results in a steady, low-shear flow that is ideal for pumping viscous fluids or those containing solids.cavity pump principle

Question 3

Applications of micro screw pump?

Accepted Answer

It is widely used in industries such as food, chemical, pharmaceutical, sewage treatment systems for quantitative dosing, electronics, batteries, energy, cosmetics, and especially in highly automated professional metering and coating systems. Examples include lithium battery coating, automotive sealing and gluing, laboratory slurries, drug mixing and proportioning, drug metering and filling, solar cell panel coating with conductive paint, and glue dispensing in the electronics industry.

Question 4

What is a progressing cavity pump function?

Accepted Answer

A progressing cavity pump is a type of positive displacement pump that uses a rotating screw-like element called a rotor to move fluid through the pump. The rotor rotates eccentrically within a rubber or elastomer stator, creating cavities that progress from one end of the pump to the other and thereby moving the fluid along. These pumps are often used in applications where a consistent flow rate, high viscosity liquids, or solids-laden fluids need to be moved.

Question 5

What progressive cavity pump uses？

Accepted Answer

Progressive cavity pumps are used in various industries for handling viscous fluids and solids. They are commonly used in industries such as food and beverage, chemical, oil and gas, wastewater treatment, mining, and construction.

Question 6

How to size a progressive cavity pump?

Accepted Answer

To size a progressive cavity pump, you need to consider factors such as the required flow rate, viscosity of the fluid being pumped, operating pressure, and the characteristics of the pump itself.

Question 7

How can use progressive cavity pump stator will be less damaged?

Accepted Answer

To minimize damage to the progressive cavity pump stator, you can ensure proper lubrication, monitor operating conditions, avoid abrasive materials, implement preventive maintenance, and ensure correct installation.
