EW pumps Parts & Tools

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 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.
