Common Challenges in Dry Claw Pump Working Conditions

Oil Mist Contamination, Oil Media Strictly Prohibited in Hydrogen Energy Processes

Oil-lubricated vacuum pumps have oil mist, and hydrogen and fuel cell processes do not allow oil intervention, which can easily cause system failure.

Requires Both Vacuum + Compression, High Cost of Two Sets of Equipment

The process requires both negative pressure vacuum pumping and positive pressure compressed air. Purchasing two pumps results in high procurement costs and occupies more installation space.

High Friction Loss, High Frequent Maintenance Costs

Rotors with mutual friction structure have fast consumption of wearing parts, requiring frequent disassembly for maintenance, increasing operation and maintenance hours and material costs.

Difficult to Find Specialized Parts, Lack of Hydrogen Energy Industry Support

Difficult procurement of dry claw pump parts, lack of professional technical services corresponding to hydrogen recirculation and hydrogen energy equipment.

Core Advantages of Leynow LC Oil-free Claw Vacuum Pump

Dry Non-contact Rotor, Clean and Oil-free Operation

High-precision claw rotors rotate synchronously in opposite directions with no physical contact. The pump chamber requires no lubricating oil, the gas is free of oil mist contamination, and it is suitable for harsh media such as hydrogen.

Dual-purpose in One Machine, Dual Use for Vacuum/Positive Pressure Compression

The same main unit, by switching pipeline interfaces, can extract vacuum negative pressure and output positive pressure compressed air, reducing the number of equipment and floor space.

Virtually Maintenance-free, Reducing O&M Investment

Non-contact rotor with no friction loss eliminates the need for frequent replacement of rotor-type wearing parts, greatly reducing the frequency of disassembly and maintenance, and saving O&M costs in the long run.

Industrial Motor, Supporting 24h Continuous Working Conditions

IP54 protected, Class F insulated motor, optimized heat dissipation, complete machine durability testing, meeting the long-term uninterrupted continuous operation of hydrogen energy and power generation equipment.

Full Series with Multiple Specifications, Adapting to Diverse Scenarios

Full model coverage from LC0100 to LC0650, from small-flow matching to large-flow complete units, usable as standalone machines or integrated systems.

Original Factory Parts, Technical Support for Hydrogen Energy Working Conditions

Filters and seals in stock as original factory parts; mature experience in hydrogen recirculation and fuel cell working conditions, with full support for selection, troubleshooting, and factory repair and maintenance.

Working Principle of Leynow Claw Vacuum Pump

  • The Leynow LC claw vacuum pump and compressor have been iteratively optimized based on decades of claw vacuum application experience. Inside, a pair of high-precision claw rotors rotate synchronously in opposite directions, with a tiny gap maintained between the rotors, achieving non-contact, frictionless, dry operation.

  • The suction-compression-exhaust process is completed through periodic volume changes. The unique feature of this machine is that the same equipment can generate vacuum negative pressure and output positive pressure compressed air. There is no lubricating oil inside the pump chamber, and no oil mist contamination; the non-contact structure results in minimal wear, making the complete machine virtually maintenance-free.

  • It is highly suitable for industrial scenarios requiring constant vacuum or constant positive pressure and oil-free operation, especially processes related to hydrogen recirculation.

Applicable Industries and Typical Processes

The Leynow LC series oil-free claw vacuum pump is dry and oil-free, dual-purpose for vacuum and compression, and is an ideal solution for working conditions such as hydrogen recirculation, transportation equipment, and stationary power generation.

  • The claw vacuum pump adopts a dry non-contact claw rotor structure with an oil-free pump chamber. It can pump vacuum negative pressure and output positive pressure compressed air, operating virtually maintenance-free.

  • It is particularly suitable for hydrogen recirculation, various transportation equipment, and stationary power generation complete systems. It can be used as a standalone machine or integrated into a complete vacuum and compression equipment set.

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 claw pump and an oil-free carbon vane rotary vane pump?

The claw rotor of a claw pump is non-contact and virtually maintenance-free, while supporting both vacuum and positive pressure output; the carbon vane rotary vane pump relies on carbon vane friction self-lubrication, and carbon vanes are consumables requiring regular replacement; claw pumps are more suitable for demanding continuous working conditions such as hydrogen energy and hydrogen circulation.

Can a claw vacuum pump be used for hydrogen recirculation?

The LC series oil-free claw pump is the preferred model for hydrogen recirculation and fuel cell matching. It is dry and oil-free and will not introduce oil media to contaminate hydrogen. Explosion-proof configurations can be provided according to requirements.

How does one claw pump simultaneously achieve vacuum and compression?

Relying on the principle of claw rotor volume change and switching pipeline interfaces, the same main unit can both pump negative pressure vacuum and output positive pressure compressed air, achieving dual-purpose in one machine.

Does virtually maintenance-free mean absolutely no maintenance?

Virtually maintenance-free does not equal zero maintenance; the intake filter needs regular inspection and the front-end filter needs cleaning; although the rotors have no contact wear, seals and bearings still need periodic inspection.

Can you provide accessories and repair and maintenance?

Yes, a complete set of original factory accessories such as filters and seals; providing technical consultation, troubleshooting, and factory repair and maintenance.
