FPH-FPHP-FPHM
Centrifugal Pump

Non-Pulsating Flow.  Long Life. Proven Sanitary Performance.

What are they?

Fristam’s Sanitary High Pressure Centrifugal Pumps (FM / FPH / FPHP / FPHM Series) are designed for demanding processing environments requiring high discharge pressures, smooth, continuous flow, and maximum uptime. Available in single-stage and multi-stage configurations, these pumps are engineered to meet the needs of filtration, reverse osmosis, and high-pressure recirculation systems—while ensuring sanitary operation.

Where are they used?

These pumps are trusted in a wide range of sanitary processing industries, including:

• Reverse Osmosis (RO) Systems
• Filtration / Ultrafiltration (UF)
• Pressure Feed Applications
• Recirculation Systems
• Dairy, Beverage, Food, Pharmaceutical & Biotech

Whether used for membrane feed, CIP return, or product transfer, Fristam’s high-pressure pumps offer unmatched reliability in high-resistance applications.

How do they work?

Fristam high-pressure centrifugal pumps utilize rotating impellers to impart velocity and pressure to the process fluid. In single-stage models (FPH, FPHP, FPHM), one impeller delivers high efficiency for elevated inlet pressures or recirculation. In multi-stage models (FM series), several impellers in series generate significantly higher discharge pressures while maintaining non-pulsating, sanitary flow.

This smooth operation ensures consistent product integrity, less wear on system components, and lower maintenance over time.

Features and Benefits

FM Multi-Stage Pumps

• Up to 4 stages for high pressure and high flow
• Withstands inlet pressures up to 1,000 PSI
• Non-pulsating performance for high product quality
