FK

Positive Displacement Pump

Circumferential piston pump – Gentle on high viscous product, with high flow rates.

Boost efficiency with FK series pumps! Designed with ultra-narrow clearances, the FK delivers powerful suction and high flow rates, even for viscous products. Engineered for high-differential heads, they excel in food, beverage, pharmaceutical and chemical industries.

Tailored Rotor Options for Maximum Performance:
The FK Series circumferential piston pumps offer unmatched precision with a choice of two rotor types, ensuring optimal performance:

  • One-wing rotors – Ideal for handling delicate, inhomogeneous products.
  • Two-wing rotors – Designed for high-speed processes with minimal shear.

Circumferential Pistons
The rotating pistons are perfectly matched to the FK’s pump body. This creates a long sealing path. Without having to use valves or other complex parts the result is a smooth product flow, free of slippage, excessive pulsation, pressure peaks or backflow loss.

Benefits of the Fristam FK Pump:

Unmatched Reliability

  • Sturdy, compact design ensures minimal downtime and long-lasting durability. Precision engineering delivers exceptional performance with low maintenance and a smart layout allows quick and easy wear part replacement.

Gentle Product Handling
Specially designed pistons ensure smooth, consistent displacement with minimal shear for gentle transportation of delicate, non-homogeneous products. This preserves product integrity across various speeds.

Precise Metering

  • Delivers exact quantities for filling applications, ensuring consistency in high-precision processes. Ideal for pharmaceutical, dairy, and chemical industries.

Hygienic Standards

  • Constructed with corrosion-resistant 316L chromium molybdenum steel (6.0 mm minimum thickness).
  • 3.1 material certification available upon request

Self-Priming Operation

  • Ultra-tight internal clearances enable vacuum operation, enabling an exceptional suction performance. Transfers even the most viscous products smoothly without rubbing or damage to itself or the product.

Constant Efficiency

  • Adjustable flow rate adapts to operating conditions by changing pump speed, keeping efficiency as high as possible, regardless of the system pressure.
  • CIP & SIP Compatible – Designed for seamless cleaning and sterilization processes

Options: ATEX, electro-polish, rectangular connections, heated jacket, drain, individual adaptations for specific products, processes and systems.

Tight Clearances

Fristam’s FK series is characterized by extremely tight clearances in the pump interior. Together with the special seal area, the FK’s short and sturdy shaft contributes to absolutely minimal distortion during process.

The FK’s excentric design principle in the mechanical seal provides functional protection against twisting and leakage. The overall results are absolute reliability and remarkably gentle operation.

Two-Wing Rotor – High-Speed Performance

As the standard rotor for the FK Series, the two-wing design is optimized for high-revolution applications. With extremely low shear, it is ideal for processing: Thick sauces, cheese spreads, soups and chocolate. This design maintains product integrity while ensuring an efficient, uninterrupted flow in demanding production environments.

One-Wing Rotor – Gentle Product Handling

Engineered for the most delicate processing, the one-wing rotor is perfect for products with large particles, such as: Fruit salads, strawberry preserves, potato salad, canned fruits & vegetables, berry compotes. Its specialized design ensures gentle movement, preventing damage to sensitive ingredients while maintaining texture and consistency.
