For companies that manufacture, rebuild, rent or develop drilling motors, the ability to test performance before a motor goes downhole can provide valuable information that is difficult to replicate in the field.

Wenzel Industries is now offering its full-scale drilling motor test stand and dynamometer system for sale from our Edmonton, Alberta facility. The DynoFlow system combines high-pressure fluid supply, controlled motor loading, measurement equipment and computer controls into an established testing installation designed specifically for drilling motors.

For a qualified buyer looking to add or expand internal motor-testing capabilities, this is an opportunity to acquire a highly specialized system rather than beginning with the engineering, sourcing and integration of an entirely new test facility.

A drilling motor may look ready for service after manufacturing or rebuilding, but controlled testing can provide another level of information before it is deployed.

The Wenzel test stand captures torque, RPM, pressure and flow simultaneously, allowing users to evaluate motor performance under controlled conditions. Torque load can also be adjusted and maintained through the system while the test arrangement is designed to minimize external force applied to the motor bearings.

That makes the equipment particularly relevant for several types of operations.

Motor manufacturers can use the system for production testing and engineering validation. Rental and service organizations can incorporate testing into QA/QC procedures before rebuilt or serviced motors return to customers. Engineering teams can compare power-section configurations, fit parameters and design changes. Organizations developing new motors or drilling technologies can also use the test stand for prototype and R&D work.

For companies currently outsourcing this work, acquiring an internal test capability may also provide greater control over testing schedules and the information available to engineering and operations teams.

This is not a general-purpose dynamometer adapted to drilling applications. The system was assembled around the requirements of full-scale drilling motor testing.

At the heart of the installation is a 700 HP Caterpillar C18 diesel engine with approximately 5,500 operating hours, driving a KAMAT 55140 triplex pump through a ZF AS Tronic transmission. The engine is housed in a heated and insulated custom-built enclosure.

The test system also incorporates an NOV Log Master II computer system and HMI touchscreen, a 60,000 lb-ft water-cooled brake system, high-accuracy load cell, hydraulic centering clamp and hydraulic tool supports. Wenzel also has original operating and service documentation for major components, as well as detailed National Oilwell Varco testing-bench computer and electronics drawings.

Key operating capabilities include 2,100 psi maximum pressure, 716 GPM maximum flow and 30,000 lb-ft maximum motor torque. The system accommodates tools from approximately 3.5 in. to 11 in. OD, with clean and dirty fluid tanks incorporated into the installation.

Building a drilling motor test facility is not simply a matter of purchasing one piece of equipment. A complete installation requires pumping capacity, power, loading equipment, controls, instrumentation, motor supports, tanks and the engineering required to make those systems operate together.

Wenzel’s DynoFlow offers an alternative: acquire an existing integrated drilling motor test stand with a documented operating history and the major supporting systems already in place.

That can be particularly compelling for a company planning to expand its motor manufacturing or rebuilding operation, establish a new regional service facility, strengthen an existing QA/QC program or develop new drilling motor technology.

Rather than waiting until additional testing capacity becomes an operational constraint, a buyer can evaluate an established system now and determine how it could fit into future production, service or engineering plans.

The drilling motor dynamometer is currently located at Wenzel Industries in Edmonton, Alberta, Canada. Wenzel welcomes inquiries from prospective buyers in Canada, the United States, the Middle East, Latin America and other international drilling markets.

Disassembly, transportation, installation and commissioning arrangements can be discussed with the eventual buyer, and on-site training from experienced Wenzel personnel may also be included as part of the sale.

If your organization manufactures, rebuilds, rents or develops drilling motors, this is an opportunity to add a capability that does not often become available as a complete system.

Contact Wenzel Industries to request detailed specifications, additional photographs, available technical documentation or to arrange a demonstration of the drilling motor test stand.
