The advantages of multistage centrifugal technology

Multistage centrifugal units are known for their reliable operation under tough conditions or in high-risk environments. That is why they are used in a variety of applications in the oil & gas, energy, or mining industries. They are suited for both pressure (multistage blowers) and vacuum (multistage exhausters) applications of air and gasses.

The strength of the multistage blower design is the ability to select both the number of compression stages and the impeller design of each stage. This will help you to match the blower performance to your process requirements with maximum efficiency.

Our ZM multistage centrifugal solutions

Whether you need air, gas, pressure, or vacuum, our wide performance range of ZM multistage centrifugal blowers and exhausters provides you with the quality you need. With a pressure up to 1.7 bar(g) / 25 psig and a flow up to 68,000 m3/hr / 42,500 cfm, they are suited for a variety of low pressure and vacuum applications that require a high flow rate.

Reliable and safe operation

Our multistage blowers and vacuum solutions are suited for operation in temperatures above 50°C / 120 °F. The stainless steel shaft and different coating options protect the unit from corrosive and dusty operating conditions and is suited for the vacuum removal of biogas, helping you decrease costly downtime of your production process. Our ZM multistage solutions are both ATEX and API 617 compliant, ensuring safe operation in demanding environments.
