Reliable Milk and Cream Transfer with Fristam’s FDS Screw Pump
When a dairy producer supplying milk for Grana Padano cheese began experiencing frequent equipment failures and hygiene issues, it knew it was time for a change. The progressive cavity pump was struggling — its rubber stator degraded quickly, leading to unpredictable flow rates, excessive downtime, and risks to product quality. To resolve these issues, the dairy turned to Fristam Pumps. The solution: a trial installation of the FDS 3L-2 double screw pump, designed for hygienic applications and challenging duty conditions.
Efficiency Without Compromise
Installed on a “Sales on Return” basis, the FDS pump was seamlessly integrated into the existing process with no layout modifications. Within weeks, it was clear the change had paid off.
Thanks to its contact-free screw design, the FDS delivered stable, wear-free performance, eliminating the gradual degradation the previous pump suffered. Operators reported that certain process phases were completed in half the time, and product quality remained consistently high even at lower speeds. The pump also handled multiple tasks — milk transfer, cream unloading, and CIP — with equal ease. Its ability to process up to 70% air without cavitation proved invaluable in maintaining flow stability with dairy products.
Low Maintenance, High Satisfaction
Staff were quick to note the quiet operation and minimal maintenance demands. With fewer interventions needed, operators could focus on other critical areas of production.
Proven Results, Trusted Partner
Following the successful trial, and building on positive experience with an earlier FDS installation on a ricotta line, the dairy has reaffirmed its confidence in Fristam as a trusted process partner. With its hygienic design, operational reliability and technical support, Fristam’s FDS pump is proving itself an ideal solution for modern dairy production.
