About Us



Monarch II Systems began when, Stephen J. King, who had over 40 years of experience in sizing and selling liquid ring vacuum pumps for various industries saw the need for a specialized product.


Prior to creating Monarch II Systems, Stephen was President of Monarch Engineered Systems for 13 years. As principal, he designed, built, and implemented vacuum systems for various industries such as water, wastewater, power, chemical, poultry and phosphate.


For a significant period, he was both a sales and research engineer, as well as, Corporate Treasurer of Clark & Vicario. Clark & Vicario was Nash Engineering Company's exclusive representative in the pump and paper industry, where for over 35 years, he developed and implemented solutions for vacuum systems.


Stephen has a patent pending on the newly designed HDPE Silencer/Separator and has previously authored a patent and co-authored two others in the area of vacuum system technology.


In 2023, Steve sold the business to a group of long-time vacuum industry professionals who look forward to continuing Steve's legacy of USA made HDPE silencers, separators and custom tanks.
