Our Story

MDM was founded as a non-metallic pump manufacturer in 1978 by Gene Ashe, a fourth generation pump specialist.  Gene’s great grandfather sold Dempster Windmills.  His grandfather purchased Shaw Pump and Gene’s father expanded the business selling Jacuzzi and Berkeley pumps.  The same way that farm and ranching families describe what they do as being in their blood and a way of life, pumps are a way of life for the Ashe family, with a fifth and sixth generation lined up to continue business development.

The inspiration for MDM was a proprietary seal design that Gene developed to be able to offer plastic pump technology for chemical processing applications, assuring fluid purity.  With insight gained as Gene says from standing on the shoulders of his forefathers, Gene bought tooling abandoned by Purex and made the product work.  Steps to develop the patented Impenatra® seal design for use in highly corrosive industrial applications have been a guide for continuous product, process and organization development at MDM – expressed in terms of Core Values.
