Common Challenges in Precision Vacuum Working Conditions

Pump Oil Backflow Contaminates the Chamber, Causing Precision Process Failure

Oil vapor backflow from oil-lubricated vacuum pumps contaminates the instrument chamber, causing test distortion and scrapping of coated products.

High Noise and Vibration, Not Suitable for Built-in Instrument Cabinets

Traditional pumps have high noise and vibration, which interfere with instruments and operators when placed in laboratories or integrated into equipment cabinets.

Shaft Seal Wear and Leakage, Process Gas Escape

Rotating shaft seals are prone to wear, causing media to leak outward, unstable vacuum degree, and inability to recover rare gases.

Complicated Maintenance, Must Return to Factory for Disassembly, Long Downtime

Replacement of wearing parts requires returning to the factory for disassembly, resulting in a long equipment downtime cycle and affecting the experimental progress of precision instrument production lines.

Working Principle of Leynow WX Dry Scroll Vacuum Pump

  • The WX dry scroll vacuum pump is based on single-sided scroll technology, integrating dry compression with a fully enclosed structure. The pump body consists of a fixed scroll and an orbiting scroll.

  • The motor drives the orbiting scroll to perform eccentric revolution, and the orbiting scroll moves along the internal track of the fixed scroll; continuously forming, moving, and shrinking crescent-shaped compression chambers; gas is drawn in from the inlet, compressed through the scroll chambers, and discharged from the central exhaust port.

  • Metal bellows static sealing, no rotating shaft seal, preventing process gas leakage; long-life lubricated bearings; maintenance only requires replacing the scroll tip seal without special tools, which can be done by the operator on-site.

  • The entire machine has low noise and low vibration, and is a well-proven dry vacuum solution for medium vacuum analytical instruments and scientific equipment.

Applicable Industries and Typical Processes

Leynow WX dry scroll vacuum pump, dry and oil-free, low noise and low vibration, oriented towards precision medium vacuum scenarios, widely used in clean processes such as instruments, semiconductors, and gas recovery.

  • The scroll vacuum pump adopts single-sided scroll dry compression and a fully sealed shaft-seal-free structure, outputting clean medium vacuum and operating virtually maintenance-free.

  • Suitable for helium leak detection, molecular pump backing pre-pumping, rare gas recovery, and precision sample processing. It can be used as a standalone machine or embedded in complete equipment as a built-in vacuum source.

Technical Information & Materials

Compiled technical reference materials related to vacuum pumps for selection, equipment commissioning, and troubleshooting.

Project Selection Reference Suggestions
  • Confirm core indicators: required ultimate vacuum, actual pumping volume;
  • Clarify the extracted medium: water vapor, dust, corrosive gases, etc., to determine whether filtration, condensation, or explosion-proofing is needed;
  • Confirm the usage environment: indoor/outdoor, on ships, high temperature and humidity, dust environment;
  • Usage mode: intermittent use or long-term continuous operation;
  • Standalone equipment or a complete central vacuum station.

Customer FAQs

What is the difference between a scroll vacuum pump and an oil-free carbon vane rotary vane pump?

Scroll pumps have non-contact fixed and orbiting scrolls, no carbon vane consumables, lower vibration and noise, fully sealed with no shaft seal leakage, and are more suitable for precision instrument leak detection and molecular pump backing; carbon vane rotary vane pumps rely on graphite carbon vane friction, and carbon vanes are consumables, making them more suitable for rough vacuum conditions such as CNC and packaging adsorption.

Can a scroll pump be used directly as a backing pump for a molecular pump?

The WX series dry scroll pump is an ideal dry backing pump for turbo molecular pumps. It is oil-free and will not contaminate the molecular pump and chamber, and is widely used in high vacuum analytical equipment.

Does "almost maintenance-free" mean no maintenance is required at all?

No; the main maintenance point is the scroll tip seal, which can be replaced on-site without returning to the factory; regularly check the intake filter; bearings are long-life lubricated, and periodic inspections are sufficient.

Is the scroll pump suitable for helium leak detection and rare gas recovery?

Highly suitable, fully static sealing with no shaft seal leakage; the pump chamber is dry and oil-free, will not contaminate helium and various rare gases, ensuring the purity of recovered gas.
