If you’ve ever struggled with inconsistent flow rates or frustrating pressure drops in your LACT (Lease Automatic Custody Transfer) units or pipeline boosting stations, you’re not alone. These pain points are common in oil and gas operations, especially when handling viscous, abrasive, or contaminated fluids. The good news? IMO 3-screw pumps offer a proven solution that tackles these challenges head-on, delivering reliable, efficient, and steady performance where it matters most.
Why Flow Loss and Pressure Drop Are Serious Problems
Accurate custody transfer and efficient pipeline operation depend on maintaining stable flow and pressure. Unfortunately, traditional pump technologies—like external gear pumps—often struggle when faced with:
- High-viscosity crude
- Variable or contaminated oil quality
- Long pipeline runs with significant friction loss
- Demanding start-stop cycles
When flow rates sag or pressure drops unexpectedly, you risk inaccurate measurement, reduced throughput, and even costly unplanned shutdowns. Over time, these issues can erode profitability and damage customer trust.
How IMO 3-Screw Pumps Address These Pain Points
IMO 3-screw pumps are engineered for the realities of oilfield and pipeline service. Here’s why they excel where other pumps fall short:
1. Superior Flow Retention
The unique intermeshing screw design of IMO pumps creates a continuous, non-pulsating flow—even with thick or contaminated fluids. Unlike gear pumps, which can lose efficiency as clearances wear or as viscosity increases, IMO screw pumps maintain tight internal sealing. This means:
- Minimal slip and leakage, even at high pressures
- Consistent flow rates across a wide viscosity range
- Reliable performance over extended service intervals
2. High-Pressure Capability
IMO LB6D and similar series are built to handle the high discharge pressures required in LACT and pipeline boosting—often up to 450 PSI (31 bar) or more. This capability ensures your product moves efficiently, even over long distances or through restrictive piping systems.
3. Robustness in Challenging Fluids
Where gear pumps can quickly wear out when exposed to sand, water, or other contaminants, IMO screw pumps’ hydrodynamic film separates moving parts, reducing abrasive wear. The result? Longer pump life and fewer maintenance headaches, even in harsh oilfield conditions.
4. Energy Efficiency and Quiet Operation
Thanks to their low internal friction and smooth, pulsation-free flow, IMO screw pumps consume less energy and generate less noise than many alternatives. That means lower operating costs and a safer, more comfortable work environment.
Comparing IMO 3-Screw Pumps and External Gear Pumps
| Feature | External Gear Pump | IMO 3-Screw Pump |
|---|---|---|
| Flow Pulsation | Moderate to high | Minimal (smooth, steady flow) |
| Handling of Viscous/Contaminated Fluids | Prone to wear and slip | Excellent, thanks to hydrodynamic sealing |
| Pressure Capability | Limited (often <200 PSI) | High (up to 450 PSI+) |
| Maintenance Interval | Shorter, frequent servicing | Longer, less frequent servicing |
| Energy Efficiency | Lower | Higher |
Maintenance Tips for IMO Screw Pumps in Oil & Gas Service
- Monitor differential pressure and flow rates to catch early signs of wear.
- Use clean, filtered oil when possible, but trust that the pump can handle occasional contaminants.
- Follow recommended lubrication and inspection intervals for optimal longevity.
- Partner with a knowledgeable supplier for genuine parts and technical support.
Conclusion
If you’re tired of battling flow instability, pressure drops, and constant maintenance in your LACT or pipeline systems, IMO 3-screw pumps are the upgrade you need. Their robust design, superior flow retention, and high-pressure capability mean you can count on steady, accurate performance—no matter what your oilfield throws at them.

FAQ
1. Can IMO 3-screw pumps handle abrasive or contaminated crude?
Absolutely. Their hydrodynamic sealing and robust construction make them ideal for fluids with sand, water, or other contaminants.
2. How do IMO pumps improve custody transfer accuracy?
By delivering consistent, pulsation-free flow even as viscosity or pressure changes, they support precise metering and measurement.
3. Are IMO screw pumps energy efficient?
Yes! Their low internal friction and smooth flow translate into lower energy consumption compared to many traditional pumps.
4. What maintenance is required for IMO 3-screw pumps?
Routine inspections and lubrication are usually sufficient. With proper care, service intervals are much longer than with gear pumps.
5. Can IMO 3-screw pumps be retrofitted into existing LACT or pipeline systems?
In most cases, yes. The HMFT team can help assess your setup and recommend the best-fit IMO solution for your needs.
