The Small Progressive Cavity Pump – A Helical Rotor Pump for Fluid Transfer

The small progressive cavity pump, also known as a helical rotor pump or a single screw pump, is a positive displacement pump that uses a single rotating screw to move fluid through the pump. The screw rotates inside a stator, which has a helical shape, creating a series of sealed cavities that move the fluid from the inlet of the pump to the outlet.

Small Progressive Cavity Pumps – Versatile and Ideal for Various Industries

Small progressive cavity pumps are widely used in many industries for various applications, such as food and beverage processing, chemical processing, wastewater treatment, and oil and gas production. They are particularly suitable for pumping viscous fluids with high solids content, as well as delicate fluids that require gentle handling.

Key Features of Small Progressive Cavity Pumps for Efficient Fluid Transfer

High Efficiency: Small progressive cavity pump have a high volumetric efficiency due to their positive displacement design, which means they can handle a wide range of viscosities and flow rates with low pulsation and shear.
Low Maintenance: These pumps have a simple design with few moving parts, and they are easy to maintain and repair in the field without dismantling the entire pump.
Self-Priming: Small progressive cavity pumps can self-prime against a dry suction line, eliminating the need for a separate priming mechanism.
Versatile: The design of these pumps allows them to handle a wide range of fluids, including abrasive, corrosive, and viscous fluids.
Cost-Effective: Small progressive cavity pumps offer a cost-effective solution for many applications, as they have a relatively low initial cost and low operating costs compared to other types of pumps.

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

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.

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.

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.

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.

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.
