About Us

Joel Pumper established Mechanical Systems Incorporated in September 2001, and the company remains family owned and operated still today. Mechanical Systems Incorporated is based on Joel’s values of honesty and ethical conduct. We work directly with your company to make sure your objectives are our objectives. We provide you with up-front cost estimates, efficient turnaround/shutdown schedules, and detailed planning. Throughout the duration of the project, we remain in contact with your company to ensure all of your goals are achieved on time and on budget.

With this attention to customer care and job satisfaction, Joel has taken Mechanical Systems Incorporated (MSI) from a home-based two-man shop, to a full-service company. MSI’s home office and primary fabrication facility are headquartered in Dundas, MN. Increased business volume led to the expansion of branch offices in Madison, Wisconsin in 2006, Fargo, North Dakota in 2010, and Broussard, Louisiana in 2016. Continued growth, evolution of services, and new product offerings give MSI the ability to manage multiple projects while continuing to deliver on their promise of quality products and services.

Despite the substantial growth, Joel’s original mission for Mechanical Systems Incorporated remains the same: Provide quality workmanship to your specifications.
