Hygienic Centrifugal Pump

Heavy Duty

Pedestal Mounted

The Industry Standard

What is the FP Series?

The Fristam FP Series Hygienic Centrifugal Pump is a pedestal-mounted pump engineered for maximum durability, efficiency, and reliability in demanding process applications. First introduced in Germany in 1936 and later brought to the U.S. on evaporator systems, the FP quickly earned its reputation as a trusted solution for industries requiring robust, hygienic pumping performance.

With its cast and forged construction, precision impellers, and self-aligning shaft design, the FP continues to deliver long service life and quiet, efficient operation for today’s most challenging hygienic processes.

Where is it Used? (Key Applications)

The FP is widely used across industries that demand cleanability, reliability, and consistent flow:

  • Dairy: Transfer of milk, cream, and yogurt
  • Beverage: Handling juices, soft drinks, and beer
  • Food: Efficient transfer of soups, sauces, and syrups
  • Personal Care: Reliable pumping of lotions, gels, and cosmetic products
  • Biopharma: Medicines, WFI (Water for Injection), and critical process liquids

How Does it Work? (Theory of Operation)

At the heart of the FP is the centrifugal pumping principle:

  • Product enters through the central inlet (eye) of the impeller
  • Optimized impeller vanes accelerate the product outward using centrifugal force
  • Liquid is directed against the casing wall and discharged through the outlet

This streamlined hydraulic design ensures maximum efficiency, gentle product handling, and reliable operation, even under challenging suction conditions.

Key Features and Benefits

Strength and Reliability

  • Heavy-Duty Construction – Cast and forged stainless steel components provide superior durability compared to stamped designs, minimizing vibration and noise while resisting hydraulic shock and cavitation.
  • Long Service Life – Rugged build quality extends pump life and protects internal parts, reducing downtime and maintenance costs.

Optimized Hydraulic Performance

  • Efficient, Reliable Flow – Engineered impellers deliver high efficiency and consistent performance under demanding conditions, even with low NPSH.
  • Gentle, Hygienic Handling – Smooth vane design protects sensitive products, reduces shear, and minimizes product waste.
  • CIP-Ready – Precision tolerances improve cleaning-in-place cycles, ensuring fast, thorough sanitation between runs.

Engineered for Savings

  • Lower Total Cost of Ownership – Energy-efficient performance, extended seal life, and minimal maintenance needs translate to long-term operating savings.
  • Easy Installation & Service – Simplified setup, quick seal gapping, and reduced adjustment requirements maximize uptime and productivity.

Available Options

The FP Series is offered in multiple sizes and configurations to match specific process needs, with a range of impeller designs, seal options, and connection types to optimize performance for your application.

 Why Choose the FP Series?

For more than 85 years, the Fristam FP has set the standard for hygienic centrifugal pumps. Combining German engineering heritage with continuous innovation, the FP delivers unmatched reliability, gentle product handling, and long-lasting performance in the most demanding applications.

When your process demands strength, efficiency, and cleanability, the Fristam FP Series is the pump you can count on.

Long Seal Life

Fristam’s unique internal seal uses the cooling and lubrication of the product to provide longer seal life. Even under extreme conditions, Fristam’s seal life is often measured in years.

Self-Aligning Shaft

A self-aligning shaft design allows for easy installation and gapping on Fristam centrifugal pumps. The concentric collar on the shaft prevents run-out, protecting the seal from damage.

Pharmaceutical Options

All standard Fristam centrifugal pump stainless steel components are 316L. Special castings are available in low-ferrite stainless steel or high-performance alloys such as Hastelloy® and AL-6XN®. USP Class VI elastomers are standard for pharmaceutical applications, with perfluoroelastomers available. Seal material options include silicon carbide, chrome oxide-coated stainless steel, and carbon. Electropolishing and enhanced internal surface finishes to 15 Ra are available on most products. Casing drain and mounting options provide complete drainability critical for long-term system cleanliness. Pumps can be easily configured for steam-in-place sterilization, with no external cooling devices required.
