Ellis Williams began his life's work with mud pumps in 1942. Researching, designing, testing—he was relentless in his efforts to build pumps with greater efficiency and durability for rugged oilfield operations.

 

Over the next 30 years, Ellis pioneered single-acting triplex pumps for oilfield drilling. He built many of these ground-breaking pumps for Brewster (the Skytop Brewster Triplex pumps). By the 1970s, most pumps in the industry were designed by Ellis Williams. Clearly, he was ready to design and build superior mud pumps under his own banner. And thus, in 1974, the Ellis Williams Company was born.

 

For the last 30+ years, the name Ellis Williams has been synonymous with efficient, innovative and extremely durable pumps. We originated the use of all-roller bearings, eccentric crankshaft and internal gears. Ellis Williams wrote the AGMA Standard (424.01) Practice for Helocal and Herringbone Gearing for Oilfield Mud Pumps. And we have continued to design and build drilling pumps without peer in the industry.

 

Today, Ellis Williams Engineering Company (EWECO) is a full service engineering and consulting company. Specializing in pumps and pump packages, we bring to our customers over 130 years of experience. We also provide consultation on pump applications, field service analysis and pump maintenance.

 

At EWECO, we wrote the book on mud pumps. But our book is a work in progress. As dynamic and rewarding as our history has been, our most exciting chapters lie ahead.
