Discover now Frigostrella’s newest release, the Ammonia/Freon 50Hz Centrifugal Pump. WIth an exclusive design, it was speclally developed to serve countries with electricity In the 50Hz format, this way Frigostrella will expand its operation area even more, focusing mainly in South America and Europe.

 The tested and approved project of the ZM Frigostrella Centrifugal Pumps has been resized to work with this 50Hz frequency on BZM models. Take a look now at the main changes of this product format:

 • Its internal recirculation chamber has been resized, thus ensuring, at nominal flow rate, the orking pressure of40mWC for electrical systems that use this frequency.

 • Besides application in 50Hz it can be used in other electric frequencies or controlled by frequency inverter, according to flow demand and pressure of the refrigeration system.

 • All performance features have been malntalned and with resizing we have made the product even more compact.

 • It has an internal recirculation chamber that prevents the occurrence of “cavitation”, Increasing the volumetric efficlency and the performance.

 It has a triple mechanical seal system that guarantees the ightness of the recirculation chamber of the cooling fluid and the oil chamber.
