Packaged Pump Systems

Mitchell Lewis & Staver’s custom engineering team can design and build a custom pressure booster or lift station to meet your unique requirements. MLS represents many major manufacturers, allowing us to select the best combination of high-performance and energy-efficient components for your application. And the technology we offer ensures that you will get the most intuitive, user friendly operator interfaces available. 

The control technology we use allows us to design your system with either manual or automatic backup systems to protect against down time, and we employ open source technology, allowing us to offer replacement parts and service in a timely manner. 

On the wastewater side, MLS represents industry leaders in the handling of sewage and storm water.  We carry a wide range of solids handling, grinder and chopper pumps to handle the most difficult waste streams for lift stations and treatment plants.  Our line of submersible and vertical mixers and aeration equipment can help keep you plant processes running smoothly and efficiently.
