GERSTENBERG POLARON PUMP
Built for performance and hygienic processing
The Polaron High Pressure Pump is carefully engineered to deliver stable, gentle product flow, protecting product integrity while ensuring efficient, reliable operation throughout your process line.
Its self-lubricating design reduces wear on moving parts, minimises maintenance requirements, and extends equipment lifespan. The pump is also fully compatible with CIP (Clean-in-Place) and sterilisation routines, simplifying hygiene management and reducing downtime.
Meeting the latest market demands for food safety and sanitary processing, the Polaron pump complies with 3-A Sanitary Standards, with all product-contact surfaces constructed from AISI 316 stainless steel or higher grades for maximum durability and corrosion resistance.
For added flexibility, the Polaron High Pressure Pump features a variable capacity easily adjusted via a frequency converter, allowing you to optimise performance for different products and production volumes.
Production capabilities and applications
The Polaron High Pressure Pump is built for versatility and seamless integration into modern fat processing lines. It’s designed to work seamlessly with the Gerstenberg Polaron SSHE (Scraped Surface Heat Exchanger), as well as to serve as a reliable, efficient upgrade when replacing older high-pressure pumps in existing production systems.
For applications such as shortening, margarine, and specialty fats, the Polaron pump can be equipped with optional nitrogen (N₂) aeration equipment, allowing for precise control of product aeration. This feature is particularly valuable for adjusting texture, structure, and density in products where aeration directly affects final quality, appearance, and performance.
The Polaron pump is engineered for a working pressure of up to 120 bar, depending on the product type and required capacity, delivering the stable, high-pressure performance essential for crystallisation, emulsification, and cooling processes. Its adjustable capacity via frequency converter makes it easy to adapt to varying production needs, offering both flexibility and process control in demanding, continuous operations.
BENEFITS OF THE POLARON HIGH PRESSURE PUMP
REDUCED PRODUCT STRESS
The Polaron pump delivers smooth, low-pulsation operation, minimising mechanical stress on margarine emulsions, shortenings, and specialty fats. This ensures consistent product texture, appearance, and quality throughout production.
MINIMISED DOWNTIME
Built for continuous operation, the Polaron pump’s robust, hygienic design reduces the risk of unplanned stoppages. Its easy-to-maintain components and CIP (clean-in-place) compatibility help keep production lines running reliably.
IMPROVED PRODUCTION EFFICIENCY
With precise pressure control and optimised energy consumption, the Polaron pump enhances overall processing efficiency. This allows manufacturers to maintain higher throughput without compromising on product quality.
LOWER MAINTENANCE COSTS
The durable, modular design of the Polaron pump simplifies routine servicing and extends equipment lifespan. Fewer breakdowns and easier parts replacement contribute to lower long-term maintenance expenses.
Trusted performance backed by experience
When it comes to processing specialty fats, shortenings, and emulsions, reliability and product integrity are everything. That’s why leading manufacturers worldwide trust Gerstenberg Services’ Polaron High Pressure Pump.
With decades of experience in designing and delivering high-performance processing equipment, Gerstenberg Services understands the demands for continuous, high-capacity production environments.

SIMPLE OPERATION & MAINTENANCE
The self-lubricating design eliminates the need for external lubrication, reducing maintenance and wear. The Polaron is also built for fast servicing and easy CIP cleaning to minimise downtime.
EASY TO ADJUST
With a variable capacity easily controlled via a frequency converter, plus both a pressure gauge and pressure transmitter, the Polaron offers precise, flexible control to suit your production needs.
MINIMAL NOISE
Mounted on vibration-resistant and adjustable feet, the Polaron pump operates at noise levels below 76 dB – even at maximum power.
Hygienic Seal-design
The pump features a built-in mesh filter designed to protect the plunger, seals and valves
from debris. The filter is made of stainless steel and is easy to remove and clean without
special tools. Mesh size is optimized for efficient filtration while maintaining high flow rates.
All metal components are manufactured from high-quality AISI 304/316 stainless steel for
corrosion resistance and long service life. All metal components are polished to Ra ≤ 0.8
μm ensuring no contamination between material and product. All O-rings and gaskets are
FDA-approved and compliant with EU Food Contact Material Regulation (EC) 1935/2004
and fully compatibility with CIP cleaning.
Media Efficiency
The Polaron pumps plunger design ensures high media efficiency with volumetric efficiencies of >95% (low slip). Its positive displacement design minimizes product loss. Hygienic, dead-space-free design further reduces media waste during cleaning and changeover.
Built-in filter
The pump features a built-in mesh filter designed to protect the plunger, seals and valves from debris. The filter is made of stainless steel and is easy to remove and clean without special tools. Mesh size is optimized for efficient filtration while maintaining high flow rates.
Hygienic Safety valve
The safety valve is designed to automatically release pressure from the pump if it exceeds a predetermined limit, preventing potential damage or failure. It ensures the system operates within safe pressure parameters.
Hygienic design
The Polaron pump is designed after 3A standard and made with a hygienic seal design in accordance with FDA and EU Food Contact Material Regulation (EC) 1935/2004. All seals are dead-space-free, ensuring no product residues remain after operation. Surfaces in contact with the medium are polished to Ra ≤ 0.8 μm. The seals are designed for CIP compatibility and are easily replaceable without special tools.
N2 Dosing equipment
Polaron pump features hygienic valves available as either spring-loaded conical valves or ball valves depending on customer needs. Optional water flush plunger seals provide cooling, reduce wear, and flush away product residues for hygienic operation. Manual or automatic N2 dosing equipment is available for production of shortening, giving the product a lighter appearance.
