ZM
Single Stage Centrifugal Pump
The ZM pump is especially designed for industrial refrigeration because it has a degasification chamber system that avoids bubbles as well as unexpected cavitation. The product entrance turbine is closed with a labyrinthic seal in order to avoid turbulence. Due to the design of its chambers, the pump does not require a specific amount of liquid for its correct functioning.
Applications
▪ Recirculation of ammonia and freons in freezer plants.
▪ No cavitation, degasification chamber that avoids the formation of bubbles.
▪ Mechanical seal with heat treated steel insert.
▪ Coupling system Bombadur ACDG® that doesn't require alingment.
▪ High performance with impellers available in accordance to flow and pressure required by installation.
▪ Three phase asynchronous, IP55 protected, flanged model type.
▪ Simple maintenance and low cost spare parts.
