Frequently Asked Questions
Q
What is the SB series sand pump designed for?
The SB series sand pump is specifically designed for oil & gas drilling operations. It features axial suction and abrasion-resistant cast iron construction to handle drilling fluids efficiently for shale shakers and mud pumps.
Q
How many models are available in the SB series, and what power ranges do they cover?
There are five models in the SB series: SB2×3, SB3×4, SB4×5, SB5×6, and SB6×8. They collectively cover a power range of 5.5 kW to 75 kW, making them suitable for light-duty auxiliary use all the way up to deep-rig applications of ≥3200m.
Q
What sealing technology does the SB series use?
The SB series features a patented dual sealing system. The primary seal is a tungsten carbide mechanical seal (Patent ZL200720079857.2), while a backup packing seal provides pressure surge protection. Lubrication is handled via grease for the shaft and oil or grease for the bearings.
Q
Are seals interchangeable between different SB models?
Yes. The seals are interchangeable between the SB5×6 and SB6×8 models. This parts commonality reduces spare part inventory requirements and simplifies maintenance on rig sites.
Q
How long does a seal replacement take in the field?
Seal replacement is designed for quick field servicing and can be completed in under 2 hours. Grease nipples on bearing covers also make routine bearing maintenance straightforward without the need for specialized tools or facility access.
Q
Has the SB series been validated in real-world drilling environments?
Yes. The SB series has been globally validated in demanding conditions: the SB6×8 achieved 18,000 hours of continuous operation in Kazakhstan land rigs; the SB5×6 handled 15% solids slurry offshore with a 2-year seal life; and the SB4×5 demonstrated less than 0.15 mm/yr corrosion in 80,000 ppm Cl⁻ brine environments.
