Jessberger Progressive Cavity Pumps: What Are They and How Do They Work?

AgiPompe has been a trusted partner of Jessberger for over 20 years, providing high-quality industrial solutions with a strong focus on progressive cavity pumps. Also known as eccentric screw pumps or single screw pumps, these pumps are ideal for transferring high-viscosity fluids, abrasive materials, or liquids with suspended solids. Thanks to their positive displacement operating principle, progressive cavity pumps ensure a steady, low-pulsation flow, making them the perfect choice for demanding applications in the chemical, food and beverage, pharmaceutical, and wastewater treatment industries.

Progressive cavity pumps operate through the rotary motion of a helical rotor inside a stator with an eccentric shape. This movement creates sealed cavities that move the fluid continuously and without pulsation. This positive displacement pumping principle allows for the efficient handling of viscous liquids and fluids containing suspended particles, ensuring a consistent and uninterrupted flow. These pumps are especially well-suited for industries that require precise, leak-free fluid transfer, such as the handling of oils, sludges, and sensitive food products. Their ability to maintain stable performance under challenging conditions makes them a reliable choice for both industrial and sanitary applications.

Eccentric screw pumps: AGI Pompe solutions

AGI Pompe, the official partner of Jessberger, offers a complete range of high-performance progressive cavity pumps, designed for the transfer of fluids with varying viscosities, including those containing solids or fibers. These pumps are known for their high efficiency, continuous flow, and low pulsation, ensuring maximum reliability even in demanding industrial environments.

Available with pump bodies in stainless steel or other corrosion-resistant materials, Jessberger pumps are ideal for numerous applications—from chemical dosing to the pumping of oils, sludges, and delicate food products such as honey, fruit juices, syrups, and doughs. Thanks to their modular design and easy maintenance, they offer excellent flexibility and are easy to integrate into various plant configurations.

A flagship model is the horizontal screw pump JP-700 H made of stainless steel 316Ti, ideal for handling fluids with variable viscosity. It is particularly appreciated for its compact construction and its ability to operate continuously even with difficult media.

To complete the range, two vertical pump models are available, designed for space-saving installations or specific industrial layouts:

- The JP-700 DR, equipped with electric and/or pneumatic three-phase motors, offers high energy efficiency and great operational flexibility.

- The JP-700 SR, featuring an integrated speed reducer and single-phase motors, is perfect for precise flow control and optimized operation in heavy-duty conditions.

Thanks to the wide variety of models and configurations, Jessberger progressive cavity pumps, distributed by AGI Pompe, represent a reliable, long-lasting, and efficient solution for every kind of industrial pumping process.
