Sanitary rotary piston positive displacement pumps





Video: Features and Benefits of Fristam's FKL-A PD Pumps

Fristam has been designing and manufacturing positive displacement pumps for over 50 years. In 1995, Fristam introduced the FKL, the first close-clearance PD pump designed for 'True CIP.'

Fristam now announces the release of the new FKL "A" for models 15–250, featuring a cleaner exterior, split-style gearbox for easy access to bearings and shafts, and customizable port-to-port dimensions for easy drop-in replacement of other PD pumps.

Models 15, 20, 25, 50, 75, and 150 are available now, with the 205 and 250 to come this summer. Original FKL models will be available until the new models are released. After that, they will be "retired." The larger models (400, 580, and 600) will remain in the original style. Please contact PureServe Systems for more information.
    Features & Benefits of the FKL Series:
  • Heavy Duty Construction
  • Balanced Rotors and Robust Shaft (Up to 25% Larger than the Competition) for Less Deflection and Wear
  • Bearing-Supported Gears
  • Tight Clearances
  • High Efficiency
  • Low Maintenance
  • Gentle Product Handling

  • Pressures to 500 PSI, Viscosity to one million centipoise (CPS)
Fristam’s high performance FKL pumps use an advanced rotary piston design to handle demanding applications. Patented technology allows these pumps to operate in demanding applications, including continuous pressures up to 500 PSI, viscosity up to one million centipoise (CPS), shear sensitive products, and adverse suction conditions.

Its balanced rotor means less deflection and wear, and also makes it possible to clean most products from the pump without disassembly or any loss of performance. Innovations in the shaft, bearings and seals increase the FKL’s robust dependability, simplify maintenance and improve pumping efficiency. Stainless steel rotors are available to handle a wider range of chemicals and pharmaceutical products.

Fristam FL 3 Series Sanitary Helical Rotary Lobe Pumps
Gentle Handling Transfer and CIP in One PD Pump

The FL 3’s unique three-wing helical rotor design expands the application range of the FL positive displacement sanitary rotary lobe pumps. The helix-shaped tri-wing rotary lobes virtually eliminate pulsation, provide reduced noice and gentle product handling, and allow higher transfer capacity and effective CIP.

They ensure an almost perfectly steady product stream, with exceptionally gentle treatment of your product. This rotor design allows the pump to be run at higher RPM to accommodate higher flow cleaning of the system (CIP).


Fristam FL 3 Series Sanitary Helical Rotary Lobe Pumps Brochure


Design: Rotary lobe pump with counter-rotating rotors designed to handle viscous and non-viscous products. Construction: Special three-wing design helical rotors allow safe and gentle product handling and virtually eliminate pulsation. Consequently the pump operates at faster speeds and reduced noise.
Advantages: Smooth operation. Higher flow rates achieved with the same pump size. Dual duty, using only one pump for product and CIP operation. Very gentle product handling.
