Frequently Asked Questions
What are the main parts of the pumping unit?
The main parts include the Motor, Reducer box, Crank, Connecting rod, Walking beam, Support frame, Base seat, and Brake device.
What is the maximum rated rod load for Type C pumping units?
Based on the specifications, the maximum rated rod load for Type C pumping units reaches up to 47,000 lbs (e.g., model C-912D-470-240).
What is the stroke range available for Type B pumping units?
The stroke lengths for Type B units range from 23 inches up to 64 inches, depending on the specific model requirements.
How much rated torque can the largest Type C gearboxes handle?
The largest positive speed gearboxes in the Type C series can handle a rated torque of up to 1,824,000 in.lbs.
Are there different models available for various load requirements?
Yes, both Type C and Type B pumping units come in a wide variety of models with different rated rod loads, stroke lengths, and gearbox torques to meet specific operational requirements.
What is the difference in application between Type C and Type B units?
While both are highly efficient pumping units, Type C models are generally designed for heavier duty operations with higher rod loads and longer strokes, whereas Type B models are suited for lighter to medium load applications.
