Well Constructed

Your transmission is as crucial to your power solution as the engine. Caterpillar engineering expertise makes sure

your transmission integrates with the rest of the power train for proven exceptional power, ease of operation, and

shifting options ideal for your well service operation.

Quality

Caterpillar manufacturing quality procedures

meet or exceed SAE, ASTM, ISO, Class A, and DIN

standards. Cat transmissions are built for your

specific application needs:

• For rugged harsh-duty applications,

TH transmissions are built with a robust

cast iron casing.

• For highly mobile applications requiring

permitted loads, CX transmissions are tough,

yet extremely lightweight.

Safety

Even more important on the job site than productivity

is safety. Cat transmissions and packages incorporate

built-in security features to keep operators and site

personnel safe on the job.

Performance

Equipment is proven in the field, and Cat purpose-built

transmissions deliver more power to the well with

fewer trailers. Our well service transmissions deliver

continuous operation under full load, smooth shifting

at any speed, and maximum uptime, with unmatched

durability and easy maintenance.

Single-source package confidence

Cat well service pumps are designed and manufactured to integrate across our product line and industry standards. High

quality materials, advanced manufacturing techniques, heat treatment processes, high-performance surface treatments,

and special coatings ensure exceptional product life and performance.

PUMP ELECTRONIC MONITORING SYSTEM (PEMS)

With PEMS technology for well service operations, you can

reduce downtime, avoid catastrophic failure, extend power

end and fluid end life — and more. PEMS collects real-time

data from onboard sensors and sends an alert to the pump

operator if that data uncovers a potential problem.

• Receive immediate notifications about impending failures

• Make smarter, faster maintenance decisions

• Keep operational interruptions and downtime to a minimum

• Use data to ensure safe operation

U.S. EPA Tier 4 Final Engines (>560 bkW/750 bhp)
