Our Mission is…

  • To inspire loyalty from our customers through solution-driven thinking and extraordinary personal service.
  • To provide a rewarding work environment for our employee owners.

 J. M. Grimstad was established in 1934 as an independent manufacturer representative for Tomkins-Johnson Cylinders and Racine Hydraulics Vane Pumps.  We have come a long way since those early years as a “basic” hydraulics company and are now proud to include leading manufacturers that allow us to expand and provide expertise beyond traditional hydraulics.  For example, Pall Corporation is a premier filter supplier for our fluid cleanliness solutions; Delta Computer Systems provides high-performance electronics controls for industrial motion control applications;  Metal Work Pneumatics offers a full line of valves, cylinders and FRL’s, and is on the leading edge of pneumatic technology.  We are the exclusive distributor of Atos hydraulic products manufactured in Italy, offering the highest level of proportional valve technology available.  Moog servo products are second to none in hydraulic servo and electro-mechanical actuator products.


J. M. Grimstad, Inc. truly is a unique company whose 100% employee ownership sets it apart from all the competition in the upper mid-west.  We have been blessed with individuals who have considerable knowledge of the industries and the highest level of technology available to serve you.  We would be honored for you to afford us the opportunity to demonstrate our expertise in motion and control solutions.
