Fristam FKL: Most Durable and Reliable PD Pump

Stop rebuilding, replacing, and spending your valuable time on other PD pumps. Fristam’s FKL pump simply runs better and lasts longer.

Engineered for lasting performance, its large diameter shaft is stronger than others. The FKL’s shaft and unique balanced rotor design reduce rotor-to-housing contact that can prematurely wear your pump. In fact, the shaft is guaranteed for life never to break.

The FKL is the first close-clearance sanitary PD pump to be designed for “True CIP.” Fristam’s FKL needs nothing removed from the pump for CIP. The cover and rotors remain in place. This provides a simple and effective solution with minimal downtime and no performance loss.

The FKL’s port-to-port dimensions can be customized for easy replacement of other PD pumps, so make the change.


What Makes the FKL Unique

Lasting Performance

"True" CIP

Easy Access Gearbox

High-Performance Alloys

Because Fristam has full machining capabilities in-house, we can provide 'super alloys' pumps when others cannot.

Versatile, corrosion resistant alloy. Very good resistance to reducing, and mildly oxidizing corrosives. Excellent stress corrosion cracking resistance.

A super-austenitic metal alloy designed to resist crevice corrosion, pitting, chloride-induced corrosion, and stress corrosion cracking.

FKL COP Version for Daily Strip Cleaning

We’ve taken the toughest, most durable sanitary positive displacement pump and optimized it for those who need to strip clean their pumps daily or between batches.

  • Robust design and construction allow for elevated pressure and longer life
  • Tight internal clearances provide high efficiency
  • O-ring seals and fewer components make assembly and disassembly simple
