About Us
Jim and Angela Murray founded the business in Colgate, Wis. in 1958. They designed and built residential sump pumps, which quickly became identified for their quality and reliability. Today, JMI Pump Systems is known as the “go to” specialist and trusted source you can turn to for even your most difficult pumping problems.
In May of 2017, Jim Murray, Jr. and his wife Patti sold the business to Mike Blum. Mike has been in the pump industry since 2006, most recently as Sales Director of Franklin Electric, which included responsibility for the Little Giant pump business. The loyal and dedicated team at JMI Pump Systems will continue to serve your needs in the tradition that we have provided since 1958.
JMI Pump Systems supplies customers throughout Wisconsin and Illinois with the right sump, effluent, sewage, and booster pumps and systems. We build pre-packaged pump systems using products from the top names in the business, including Little Giant, Barnes, Metropolitan Industries, Tsurumi, Glentronics PHCC, Topp Industries, SJE Rhombus, Alderon, Jackel and more.
OUR STAFF
With a combined total of more than 175 years of industry experience, the staff of JMI Pump Systems is comprised of a well-trained, hands on group of individuals that have real life experiences working with the products we sell.
In addition to the product knowledge, we get to know our customers by asking the right questions. We go overboard to insure that they get the right product for their applications.
We routinely instruct approved continuing education classes for plumbing license renewal in both Wisconsin and Illinois.
Real people making the real difference.
