Gas & Diesel Engines
Prime mover engines power the beam pumping units, compressors, and auxiliary equipment that keep oilfield production running. Selecting the right engine — matched to the load, fuel type, altitude, and ambient temperature of the application — directly affects fuel efficiency, maintenance intervals, and equipment uptime.
Proxima supplies gas and diesel engines for oilfield applications through Power Flow International Sales, representing Arrow Engine, Waukesha, and Caterpillar.
Oilfield Engine Applications
- Beam pump / pumping unit drives
- Natural gas compressors
- Water injection pump drives
- Wellsite power generation
- Auxiliary and utility equipment
Engine Range
Arrow Engine — Natural Gas Engines
Arrow Engine Company manufactures natural gas engines specifically designed for oilfield service. Arrow engines run on field gas — eliminating diesel fuel costs — and are built for continuous-duty operation in remote wellsite conditions. They are a standard prime mover for beam pump units across North America and international markets.
Available in a range of horsepower ratings to match pumping unit requirements. Parts availability and service support are provided through Power Flow.
Waukesha Engines
Waukesha manufactures high-performance natural gas engines for compressor drive and power generation applications. Known for high thermal efficiency and long service intervals, Waukesha engines are widely used in gas compression and processing facilities.
Caterpillar Engines
Caterpillar diesel and gas engines cover a broad power range for heavy-duty oilfield and industrial applications. Used where diesel fuel is preferred or where higher power output is required than natural gas engines provide.

Frequently Asked Questions
Q: Can Arrow engines run on associated field gas?
Yes. Arrow natural gas engines are designed to run on field gas, including gas with varying BTU content. Specify the gas composition when ordering to ensure the correct carburetion setting.
Q: What maintenance intervals are typical for an Arrow Engine on a beam pump?
Maintenance intervals depend on engine model and operating conditions. Typical oil change intervals are 250–500 hours. Proxima supplies engine manuals and maintenance schedules with all engine orders.
Q: Can Proxima supply replacement engines for existing pumping units?
Yes. Provide the pumping unit model, required horsepower, and existing engine configuration, and we will specify a replacement engine. Power Flow has extensive experience matching engines to existing equipment.
