Frequently Asked Questions
What drilling applications are SB series sand pumps designed for?
SB series sand pumps are specifically engineered for oil & gas drilling operations. They are used to transfer drilling fluids between shale shakers and mud pumps, handling abrasive slurries with high solid content in both onshore and offshore environments.
What is the power range available across the SB series models?
The SB series covers five models ranging from 5.5kW to 75kW. The SB2×3 starts at 5.5kW for light-duty tasks, while the SB6×8 reaches up to 75kW for deep rigs (≥3200m). This range ensures suitable options for virtually every drilling scenario.
What patented sealing technology do the SB pumps use?
SB series pumps feature a dual sealing system protected by Patent ZL200720079857.2. The primary seal uses a tungsten carbide mechanical seal for superior wear resistance, backed by a packing seal for pressure surge protection. Lubrication is provided via grease for the shaft and oil or grease for the bearings.
Are seals interchangeable between different SB models?
Yes. Seals are fully interchangeable between the SB5×6 and SB6×8 models. This parts commonality simplifies spare parts inventory management and significantly reduces downtime during maintenance on rig sites.
How quickly can seal replacement be completed in the field?
Seal replacement on SB series pumps can typically be completed in less than 2 hours under field conditions. The design prioritizes ease of maintenance, with grease nipples on bearing covers for straightforward bearing servicing without requiring specialized tools.
What is the lead time for spare parts delivery to rig sites?
We offer a 48-hour spare parts delivery commitment to rig sites worldwide. Combined with reversible volute conversion support and our global service network, SB series pumps are backed by comprehensive after-sales support to minimize operational downtime.
