Houston, Texas -- To eliminate equipment compatibility issues and the prospect of additional spare-parts inventories for drilling contractors, the LeTourneau Ellis Williams Company (LEWCO) can factory-equip its heavy-duty W-Series and general-duty WH-Series mud pumps with virtually any major brand of fluid end module. Customers not specifying a particular brand receive LEWCO"s standard one-piece or two-piece fluid end modules made of quenched and tempered forged steel, featuring "off the shelf" expendables readily available from domestic and international sources.

LEWCO mud pumps are in-house manufactured. For maximum quality assurance -- with job-ready performance verified in advance -- every pump is tested under full load prior to shipment, in the company"s fully equipped, million-dollar "mud pump laboratory." LEWCO pumps provide input ratings of 300 to 3,000 horsepower (224 kW to 2,237 kW) and deep-drilling discharge pressures as great as 7,500 pounds per square inch (527 kg/cm2). Their premium components include a pressurized lubrication system that force-feeds lubricant to all power-end bearings including upper and lower crosshead slides; a balanced forged steel crankshaft that reduces noise and vibration and helps extend component life throughout the pump; and a robust frame of double-wall, welded-steel, mounted on a heavy-duty oilfield skid.

The LeTourneau Ellis Williams Company builds high-performance mud pumps for oil and gas drilling (on land and offshore), petroleum production and processing, well-servicing, and horizontal directional drilling; as well as ancillary drilling products including pulsation dampeners; drawworks; rotary tables, transmissions, and drives; and swivels. Located in Houston, Texas, LEWCO is a wholly owned subsidiary of LeTourneau Incorporated, a leading manufacturer of self-elevating offshore drilling rigs, forestry equipment, and wheel loaders.

The 2,200-hp mud pump for offshore applications is a single-acting reciprocating triplex mud pump designed for high fluid flow rates, even at low operating speeds, and with a long stroke design. These features reduce the number of load reversals in critical components and increase the life of fluid end parts.

The pump’s critical components are strategically placed to make maintenance and inspection far easier and safer. The two-piece, quick-release piston rod lets you remove the piston without disturbing the liner, minimizing downtime when you’re replacing fluid parts.

Cameron manufactures high-performance, robust LEWCO™ mud pumps for onshore and offshore oiland gas drilling applications. Each mud pump features a one-piece, forged and fabricated alloy steelcrankshaft for smooth operation and enhanced longevity. In addition, LEWCO mud pumps includea welded steel power frame, forged alloy steel pinions and gears and triple-redundant power endlubrication. Prior to delivery, LEWCO mud pumps are tested in our quality control facility to verifyperformance expectations.

For maximized drilling performance and efficiency, LEWCO mud pumps offer high discharge flow rates,impressive power-to-weight ratios and small footprints. Cameron can also furnish fluid end modulesto match the customer’s existing inventory. Cameron takes pride in their ability to provide integratedpump packages, including top or rear mount AC or DC electric drives, controls, manifolds, piping andaccessories. Pumps are installed on a heavy-duty skid or trailer mounted for portability.

One-Piece Forged and Fabricated Alloy Steel Crankshaft The power balanced crankshaft reduces noise and vibration and extends the life of the bearing and crankshaft life. Rather than using a multipiece bolted component, the LEWCO crankshaft is made of one-piece, forged and fabricated alloy steel construction. It is repairable to help reduce operating expense and its bearings are lubricated via drilled internal passageways for longevity.

Welded Steel Power Frame The mud pump power frame is engineered for performance, reliability and toughness. Designed for discharge pressures as high as 7500 psi, it is an independent, precision-fabricated structure of double-wall welded steel, with stiffeners and gussets for added strength and durability. As opposed to pumps mounted on an integral skid, LEWCO mud pumps come mounted on a heavy-duty oilfield skid for mobility and increased alignment capability, reducing component wear caused by internal stresses.

Triple-Redundant Power End Lubrication The LEWCO triple-redundant, filtered lubrication system includes internal gravity/splash plus internal/external force-feeding of most of its power end bearings and upper/lower crosshead slides. For protection even at low operating speeds, the system includes a gear-driven mechanical pump off the main gear and a second pump driven by an electric motor.

Fluid End Modules LEWCO fluid end modules are available in one or two-piece configurations using quenched and tempered forged steel material. Cameron can furnish fluid end modules compatible with various mud pump brands already in use, eliminating the need to stock extra spares. Fluid end expendables are off-the-shelf parts, readily available from domestic and international Cameron facilities, further minimizing the need for additional stocking.

Steel Connecting RodsThe LEWCO rolled plate, low-carbon steel connecting rods maintain precisealignment between the crankshaft and crosshead under maximum load. These rodsfeature double-row cylindrical roller bearings in the crosshead end and single rowcylindrical bearings in the crankshaft end, reducing wear and friction under severeoperating conditions.

Discharge Manifold and CrossMade of forged, heat-treated steel for ruggedness, LEWCO discharge manifolds aredesigned to provide reliable connections and easy module maintenance. The piecesare available in working pressures of 3000, 5000 and 7500 psi and in various flangeoutlet configurations with clean-out strainers. On LEWCO pumps, the single-piece,trepanned manifold mounts directly to the front or back of the fluid ends, whicheliminates connections between the discharge modules.

Developed for increased mobility, the WH-Series mud pumps deliver high performance in a compact design. Featuring small footprints and less weight, these pumps are ideal for applications where space is limited. LEWCO mud pumps feature a power balanced, single-piece forged steel crankshaft for smooth operation.

Continental Emsco Drilling Products, Inc., which consisted of Emsco drilling machinery and Wilson mobile rigs, was purchased by National-Oilwell, Inc on July 7, 1999. To our knowledge, no pumps have been manufactured and sold under the Emsco brand name since National-Oilwell acquired them.

Fairbanks Morse pumps are currently manufactured in Kansas City, Kansas. Fairbanks Morse is a division of Pentair ever since August, 1997 when Pentair purchased the General Signal Pump Group.

Gaso pumps are manufactured by National Oilwell Varco. Gaso was acquired as "Wheatley Gaso" by National-Oilwell in the year 2000. At the time, Wheatley Gaso was owned by Halliburton.

Skytop Brewster pumps are no longer available as new pumps. Skytop Brewster(Cnsld Gold), a unit of Hansen PLC"s Consolidated Gold Fields subsidiary, was acquired while in bankruptcy by National-Oilwell, Inc. in November, 1999.

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 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.

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.

The Ellis Williams Company (EWCO) is renamed to LEWCO, because of LeTourneau Technologies Drilling Systems, Inc. The Company has been renamed LEWCO and has greatly expanded in its operations under the Rowan / LeTourneau ownership. Mr. Ellis Williams still serves as a consultant to LEWCO and realized one of his career dreams when the first EWCO 3,000 horsepower pump was completed in early 2002

We do have all LEWCO / EWCO / Ellis Williams parts available and in stock and ready to be shipped in Europe or elsewhere. This can be original and OEM parts, however the customer wishes.
