What is a Variable Primary Flow Pumping System?


Low Installed Cost. High Efficiency.

Variable primary flow (VPF) pumping systems offer many benefits for water-cooled, as well as some air-cooled, chilled water pumping designs.

In this video, YORK® experts share an example of a water-cooled system to detail what a typical VPF pumping system looks like. Using comparisons to other pumping systems, you'll see why VPF is the most popular pumping system currently in use.

Variable primary flow (VPF) pumping systems increase efficiency and provide a low install cost.
