Product Description
15-105-RHBM Small Model Mechanical Seating Sucker Rod Pump
This small model mechanical seating sucker rod pump is engineered for reliable downhole operations in oilfield applications, featuring robust construction and API-compliant design standards.
API Classification System
Sucker rod pumps are classified according to API Spec. 11AX standards based on barrel type, seating location, and assembly configuration. The complete API designation includes:
- Nominal tubing size (1.9" to 4.5" OD)
- Basic bore diameter (1.0625" to 3.75")
- Pump type (rod or tubing)
- Barrel type (heavy, thin, or X type)
- Seating assembly location (top or bottom)
- Seating assembly type (cup or mechanical)
- Barrel length and plunger length specifications
- Upper and lower extension lengths when required

Pump Components
Complete pump assembly includes standing and traveling valves, plunger, barrel, seating assembly, pull tube or valve rod (for insert pump), and all necessary fittings for secure assembly.
Setting Depth Considerations
Maximum recommended setting depth is determined by API RP 11AR standards, which analyze burst, collapse, and axial-loading stresses on pump barrels and components. Proper selection of size, type, and metallurgy is essential for optimal performance and longevity in downhole applications.
