History of Trinity Pump Products

Robert E. Oklejas (Rob) started his career in the pump industry over 20 years ago with Pump Engineering, Inc. (PEI). His work with PEI primarily involved building a Swiss sales & service facility to support the European and Middle East reverse osmosis industry.  Pump Engineering, Inc. focused on developing and manufacturing pumps, parts and supplying various services to the Reverse Osmosis market. Rob went on to be the founder and managing director of Trinity Pumpenwerk GmbH in Weil am Rhein, Germany.  Trinity Pumpenwerk focused on providing pumps, parts and service to the European Horizontal Directional Drilling market. This company was sold to Prime Drilling GmbH (a major horizontal directional drilling rig manufacturer) in July, 2012.  Returning to the USA after the sale of Trinity Pumpenwerk, Rob and his wife Laura created TRINITY Pumpworks to provide high quality, market driven pump products to select markets.

Rob was born in Monroe, MI and studied business commerce and manufacturing processes.  Robert is a decorated US Army combat infantryman having served in both the Desert Storm and Desert Shield conflicts. Having lived in and traveled extensively through Europe and the Middle East, Robert has at least cursory knowledge of several languages and is especially fluent in German.
