Industrial Screw Vacuum Pumps

Oil-Injected & Oil-Free Series

Core Advantages

• Intelligent Drive – Adaptive power management lowers energy bills by up to 50%, suppresses inrush current, and maintains 97.5% operating efficiency.
• Advanced Separation – Proprietary 3-stage oil removal system reduces running costs, extends overhaul intervals, and cuts servicing time on lubricated units.
• Dual-Zone Thermal Design – Isolated hot and cold sections block steam condensation, safeguard sensitive electronics, and dampen operating noise.
• Heavy-Duty Engineering – Robust airends, sealed IR motors with extra-large bearings, and EC variable-speed fans deliver steady output with minimal vibration.

Oil-Lubricated Screw Pumps

Oil-Free Screw Pumps

F A Q

Q: Which version should I choose – oil-injected or oil-free?
A: Oil-injected units offer higher throughput and deeper vacuum (0.35 mbar), making them ideal for heavy industrial duty. Oil-free variants eliminate any risk of process contamination, so they are preferred in clean production lines, medical device manufacturing, and sensitive R&D environments.

Q: Is the energy-saving claim proven in real operation?
A: Yes. The closed-loop regulation continuously matches pump speed to system demand. Field data shows typical savings of 40–50% versus conventional on/off or throttle-controlled pumps, with peak efficiency exceeding 97%.

Q: What about noise and footprint?
A: The thermally split enclosure and precision-balanced rotors keep sound levels remarkably low. Compact skid designs (dimensions listed in full catalog) fit tight machine rooms without compromising service access.

Q: How does the 3-stage separator improve maintenance?
A: It reduces oil carry-over, so downstream filters stay cleaner for longer. The cartridge design allows quick element replacement without special tools – typical service intervals are 2× longer than conventional two-stage separators.

Q: Can these pumps run under high ambient temperatures?
A: Yes. The independent cooling circuit, oversized heat exchangers, and intelligent thermostatic bypass valve maintain stable thermal balance even in hot workshop conditions up to 45°C.

Q: Are the drives compatible with existing plant control systems?
A: Absolutely. Standard Modbus RTU/TCP, Profibus, and analog I/O interfaces enable seamless integration with PLC, SCADA, and building management networks.
