Lobe Pump

Gentle Product Handling with Maximum Efficiency

What is the FL2 PD Pump?

The Fristam FL2 Positive Displacement Pump is a sanitary, bi-wing rotor pump engineered for applications requiring product integrity, clean-in-place (CIP) capability, and easy maintenance. Built to handle viscosities up to 100,000 cps and pressures up to 170 PSI, the FL2 offers reliable, efficient operation for a wide range of sanitary processing industries.

Where is the FL2 Pump Used? (Key Applications)

The FL2 is trusted in industries where cleanability, gentle handling, and operational efficiency are critical, including:

• Food & Beverage Processing — sauces, syrups, oils, and yeast
• Dairy & Cheese Manufacturing — yogurt, cream, curds, and whey
• Pharmaceutical Production — sterile fluids, ointments, and suspensions
• Brewing & Distilling — yeast slurries, flavor concentrates
• Cosmetic & Personal Care — lotions, creams, and gels

How Does the FL2 Pump Work? (Theory of Operation)

The FL2 utilizes a low-slip bi-wing rotor design, creating large displacement cavities that move product gently with a smooth, circular motion. This design minimizes shear and protects sensitive products from damage.
The long slip path of the bi-wing rotors also improves volumetric efficiency — even when handling low-viscosity products or operating at elevated temperatures. Simple external timing gears prevent rotor-to-rotor contact, while precision manufacturing ensures repeatable performance with every cycle.

Features & Associated Benefits

• Low-Slip Bi-Wing Rotors
  • Minimize shear for gentle product handling and reduced slip, maintaining efficiency across a range of viscosities.
• Tool-Free, Pinless Seal Design
  • Allows quick maintenance with a unique locking system—no pins, set screws, or guesswork required.
• Universal Mounting & Easy Timing
  • Simplified rotor gap setting outside the gearbox with a spacer ensures fast, accurate maintenance.
• Extended Life Oil Lubrication
  • Oil-bath bearing system lasts up to 8 times longer than grease, reducing maintenance intervals and downtime.
• CIP & SIP Cleanability
  • Clean-in-place with rotors installed. Optional high-temperature rotors allow for sterilize-in-place (SIP). Vertical mounting ensures full self-drainability.
• Optional Jacketed Housing
  • Enables precise temperature control for heat-sensitive products like chocolate, oils, and brewer’s yeast.

Available Options:

• High-Temperature Rotors for SIP applications
• Jacketed Pump Housing & Cover for thermal control
• Pharmaceutical Package:
  • 15 Ra Surface Finish & Electropolish
  • Silicon Carbide Seals & USP Class VI Elastomers
  • Full Validation Documentation
