The EWECO Story. 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-plus years, the name Ellis Williams has been synonymous with efficient, innovative and extreme-ly 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 Helical and Herringbone Gearing for Oilfield Mud Pumps. And we have continued to design and build drilling pumps without comparison 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 reward-ing as our history has been, our most exciting chapters lie ahead.

The EWECO Advantage.It’s all about performance. At EWECO, our pumps are designed to deliver maximum performance with minimum pump weight. For us, that means greater horsepower per pound. Higher horsepower pumps—with a smaller footprint and lighter weight—shorten completion time. And because of superior design, EWECO pumps have a longer life expectancy and work a lot harder. In fact, our pumps are rated for 24 hour-a-day true continuous duty.

All EWECO pumps are manufactured in the USA. We cut our own patented herringbone gears which contribute to the longer life span of EWECO pumps. Our crankshafts are also a cut above. Instead of the automotive style, we make all eccentric crankshafts with anti-friction bearings for 25 percent greater efficiency. And while others use cast iron, EWECO’s longer-lasting crankshafts are constructed with forged steel.

In addition to our renowned triplex pumps, EWECO is one of the few companies in the industry to offer quintuplex pumps. In drilling situations where size and weight are critical, these innovative pumps can be extremely cost efficient.

No matter which models are right for your projects, you can depend on EWECO for quality, efficiency and longevity. Indeed, EWECO pumps deliver 95-99 percent mechanical efficiency.

A big advantage for your company, and for the environment, too.

EWECO Mud PumpsFrom design to construction, EWECO pumps are intended to meet tough and exacting standards. Manufactured in our own machine shop, every EWECO pump is fabricated with a high-strength, heat-treated alloy steel power frame. This method allows for easy modification of pump designs to meet your custom applications.

With over 125 utilization methods, EWECO can provide complete pump packages, including prime movers, controls, manifolds, piping, accessories and so on. We can mount equipment on heavy-duty oilfield or industrial type skids. We can also supply portable-trailer mounted units, top drive electric motor-driven units, or whatever your particular requirements demand.

EWECO includes the suction stabilizer on all units. We can also provide each with suction equipment, including discharge dampeners, gauges, relief valves, charge pumps and the like.

Regardless of the size or scope of your project, EWECO has the experience and resources to handle the job. At the same time, you can count on us for fast, flexible and personal service.

Calculate Rod Load

Plunger Load or Piston Load = Pd x Face Area or Piston or Plunger

Calculate Horsepower (input HP required at pump pinion shaft or crankshaft)

Horsepower for Single Acting Pump=(GPM)(PD)(100) - (GPM)(Ps)(Em-5%) (1714)(Em) (1714)(100)

Horsepower for Double Acting Pump= (GPM)(Pd-Ps)(100) (1714)(Em)

Nomenclature:

Pd = Pump Discharge Pressure (PSI)Ps = Pump Suction Pressure (PSI)Em = Pump Mechanical Efficiency (in decimal form: i.e. (0.9), (0.85))GPM = U.S. Gallons Per MinuteRPM = Revolutions Per Minute Of Pump Crankshaft
