Fristam FZ Pump Hygienic side-channel pump

The Fristam FZ is a hygienic side-channel pump designed for the reliable handling of liquids containing air or gas. Based on the liquid ring principle, it enables continuous pumping of aerated media where standard centrifugal pumps would lose performance or air lock.
The FZ is particularly suited to tank emptying, line evacuation and CIP return processes, where strong suction capability and consistent flow are essential.

Designed for aerated and return processes:
Unlike conventional centrifugal pumps, the FZ can handle air-liquid mixtures without interruption, maintaining stable operation even under fluctuating conditions. Its design allows for complete draining of tanks and pipelines, reducing product loss and improving process efficiency.

Key benefits:
• Side-channel (liquid ring) technology for pumping liquids with entrained air or gas
• Reliable, self-priming operation for suction and return applications
• Continuous flow with aerated media without air locking
• Efficient tank and line emptying to minimise product loss
• Hygienic design suitable for CIP processes and regulated industries

Typical applications:
• CIP return systems
• Tank and vessel emptying
• Aerated or foaming products
• Food, beverage and pharmaceutical processes

The Fristam FZ provides reliable, hygienic pumping wherever air and liquid must be handled together.
