Centrifugal sand pumps, commonly known as Mission-style pumps or SB series pumps, play a critical role in oilfield drilling operations. These supplementary pumps are specifically designed and manufactured to handle the demanding conditions of petroleum and natural gas drilling equipment. Featuring an axial suction structure and wear-resistant cast iron for flow-passing parts, they excel at transporting corrosive drilling fluids containing suspended particulates or similar media.
These pumps are ideal for feeding desanders, desilters, and jet mud mixers, as well as serving as charging pumps for triplex mud pumps in solids control systems. Their robust construction ensures reliable performance in abrasive and viscous environments, making them essential for efficient mud circulation and solids removal.
Key Features of SB Series Centrifugal Sand Pumps
The conventional SB series models for oilfield applications include:
- SB10×8×14
- SB8×6×14
- SB6×5×14
- SB5×4×14
- SB4×3×13
- SB3×2×13 (or similar variants like SB2×3×13)
Sub-models vary based on impeller diameter, which directly impacts performance metrics such as flow rate, head, and power requirements. Available motor powers range from 5.5 kW to 75 kW (including common options like 7.5 kW, 11 kW, 15 kW, 22 kW, 30 kW, 45 kW, 55 kW, and 75 kW). Pump speeds are typically 1450 RPM (for 50Hz systems) or 1750 RPM (for 60Hz systems), depending on voltage and frequency.
These pumps offer excellent wear resistance, open or semi-open impeller designs for handling solids, and mechanical seals for extended service life.
How to Select the Right Centrifugal Sand Pump
Proper selection of a centrifugal sand pump is essential for optimal performance in mud solids control systems. The primary factors to consider are:
1. Required Flow Rate and Head: Match the pump to the feeding volume and pressure needs of your solids control equipment (e.g., desanders, desilters, or mud mixers).
2. Drilling Rig Capacity: Pump size often correlates with rig depth and mud volume.
- For ZJ30 rigs: Typically equipped with a 30 kW sand pump.
- For ZJ40–ZJ50 rigs: Often use a 55 kW sand pump.
- For ZJ70 rigs: Commonly paired with a 75 kW centrifugal pump.
3. Fluid Properties: Account for viscosity, specific gravity, abrasiveness, and corrosiveness of the drilling mud.
4. Application-Specific Needs: Larger pumps (e.g., SB8×6×14 or SB10×8×14) for high-volume, deep-well operations; smaller ones (e.g., SB4×3×13) for charging or auxiliary roles.
Always consult performance curves and ensure compatibility with your system’s power supply and space constraints. Over-sizing can lead to inefficiency, while under-sizing may cause inadequate circulation.
