LEWCO Parts & Tools

LEWCO is the producer of industrial pumps. The company started producing Ellis Williams pumps since 1974. We use industrial pumps in our pumping units, high pressure pump and mix pump units.

Pumping units at SiteTec HDD Equipment

Pumping units are used to pump drilling fluids to the drill rig during a horizontal or vertical drilling. Our units are built to pump bentonite based liquids, grout and other drilling fluids. Our range of pumping units varies in capacity of 10 up to 3500 liters per minute and up to 150 bar.

Ellis Williams / LEWCO / EWCO Pumps

Ellis Williams / LEWCO / EWCO Pumps are not a standard in our units. The time of delivery is too long and the transport costs are too high. On customers request we do built them in our units. Therefor we service them and have all wear parts available. Last year we purchased 2 Ellis Williams pumps, type 446 high and a type 440, both pumps received a complete overhauling and were used to construct our rental high pressure pumping unit P2500D and P2500E.

Ellis Williams Company (EWCO)

The Ellis Williams Company, Inc. (EWCO), Houston, Texas, is a manufacturer of premium reciprocating mud pumps, which are used in oilfield drilling and Horizontal directional drillings. The founder, Mr. Ellis Williams, is a pioneer in mud pump design and manufacture. EWCO was owned by Michael and Shirley Williams, and Bob and Ken Gibbs. The owners engaged DAG to find a buyer with two objectives in mind – shareholder liquidity and the ability to expand the EWCO pump line. After an extensive search, DAG negotiated the sale of EWCO to Rowan Companies, Inc. (NYSE:RDC) subsidiary LeTourneau, Inc. EWCO was sold at an attractive multiple which was well received by each shareholder. Management stayed in place through a transition period.
