Overcoming Traditional Vacuum Pump Limitations
Reducing operational costs, improving production efficiency, and adapting to demanding process requirements. Ultimate vacuum capability down to 1Pa.
High Energy Consumption & Environmental Pollution
Traditional vacuum systems waste power at common duty points, inflating total cost of ownership while contributing to environmental pollution through excessive energy usage.
Superior Energy Efficiency & Eco-Friendly
Our optimized approach delivers superior energy efficiency and environmental benefits:
- Optimized screw profile geometry improves volumetric efficiency in typical high-vacuum ranges
- Application-tuned controls (VFD-ready) to match load fluctuations and reduce off-design losses
- Dry-process–friendly configuration options to minimize parasitic losses from working fluids
Frequent Maintenance & Downtime
Complex internals and wear-prone parts force frequent stops, hurting OEE (Overall Equipment Effectiveness) and increasing operational costs.
Extended Maintenance Intervals
Engineered for reliability and easy maintenance:
- Non-contacting screw profiles reduce internal wear under clean-process conditions
- Special alloy materials effectively extend overall equipment lifespan
- Modular layout provides fast access to serviceable components, shortening planned downtime
- Condition-monitoring interface (sensors-ready) helps move from reactive to planned maintenance
Complex Process Requirements
Processes involve condensables, solvents, or variable loads that standard pumps struggle to handle effectively, limiting operational flexibility.
Configurable for Your Application
Customizable to meet specific process demands:
- Process-specific materials & sealing options to improve compatibility with challenging gases/vapors
- Thermal management & gas handling options (purge/inerting readiness) to mitigate condensation risk upstream
- System-level integration capability for central vacuum or multi-pump cascades
Manufactured with Mazak/Matsuura precision equipment
Backed by 25 patents in screw technology and continuous R&D investment
SDHV vs Traditional Solutions
See how SDHV Screw technology compares to traditional vacuum solutions across key performance metrics
| Criterion | SDHV Screw | Liquid Ring | Roots (Booster System) |
|---|---|---|---|
| Specific Energy @ Declared Duty Point | Lower at matched duty point | Higher due to working fluid affected by temperature rise | Depends on backing pump sizing |
| Utilities Consumption | 0 L/h (if dry configuration) | Continuous seal water required | 0 L/h (water) |
| Maintenance Interval | Extended (clean-process, fewer wear parts) | Periodic (scaling/cavitation risks) | Periodic (gears/seals; plus backing pump) |
| Process Compatibility | Configurable materials/seals | Good with wet gases; risk of cross-contamination | Limited with condensables without traps |
| System Complexity | Single primary unit | Internal liquid circulation in pump body | Booster + backing pump |

Test Conditions & Methodology
Test Gas: Dry air (20 °C, 1 atm at inlet)
Configuration Notes: Liquid Ring includes seal-water loop at rated conditions; Roots considered as booster + backing pump sized for the same duty point; SDHV standard configuration without ancillary process traps unless otherwise stated.
Maintenance Interval: Estimated under clean-process assumptions; actual interval depends on gas load, particulates, condensables, and duty cycle.
