Leynow Vacuum Units | Integrated Vacuum Systems, Central Negative Pressure Stations, Roots Water Ring and Roots Rotary Vane Unit Customization Manufacturer

Common Challenges in Vacuum System Projects

Traditional vacuum systems often face four major pain points in construction and operation.

Scattered Procurement and Self-Assembly, Many Leak Points and Pressure Fluctuations

Separately purchasing pumps, tanks, electrical controls, and filter parts, assembling on-site, resulting in many pipeline joint leak points, unstable vacuum pressure, and large process fluctuations.

Incorrect Pump Unit Matching and Selection, Failing to Meet Process Indicators

Unreasonable matching of the main pump and backing pump, pumping speed and ultimate vacuum cannot meet production process requirements, resulting in low production efficiency.

Manual Operation without Protection, No Fault Warning

No automatic control system, relying on manual start/stop; lack of overload and high-temperature alarms, sudden fault shutdowns causing production losses.

Multi-Workstation Decentralized Pump Configuration, Complicated O&M Management

Multiple equipment in the workshop each equipped with a vacuum pump, large number of equipment, high noise and energy consumption, scattered maintenance points, and high management costs.

Core Advantages of Leynow Integrated Vacuum System

Targeting industry pain points, Leynow provides one-stop integrated solutions.

Complete Integration from the Factory, Plug and Play

Pump main unit, buffer tank, PLC electrical control, filtration and separation, and automatic drainage are integrated and debugged in the factory; ready to use on-site by connecting pipelines and power, reducing leak point risks and on-site workload.

Scientific Pump Unit Ratio, Combined on Demand

Multiple pump unit solutions such as Roots-water ring and Roots-rotary vane; selection and ratio are based on medium, vacuum degree, and pumping volume to avoid energy waste.

PLC Fully Automatic Control, Multiple Safety Protections

Automatic pressure start/stop, pump rotation operation; overload and high-temperature fault audible and visual alarms; can interface with MES, multi-pump rotation in central stations, extending equipment life.

Medium Pre-treatment Module, Protecting the Main Unit

Configurable intake filtration, gas-water separator, condensation recovery, and automatic drainage units to handle water vapor, solvents, and dust, reducing the probability of pump failure.

Two Modes: Standalone Unit / Central Negative Pressure Station

Select independent units for single process equipment; build a central vacuum pipeline network for multi-workstation workshops, one system supplies multiple equipment, simplifying the site and saving costs.

Non-standard Customization, Full Set of Engineering Services

Non-standard sizes, explosion-proof configurations, and redundant backups can be customized; one-stop support including working condition survey, solution drawings, supply, on-site guidance, and parts maintenance.

Working Principle of Leynow System and Unit Products

Leynow integrated vacuum units/central negative pressure stations scientifically match the main pump and backing vacuum pump according to the process target vacuum degree and pumping volume. Gas passes through the intake filtration and gas-water separation pre-treatment units before entering the pump unit; after pre-pumping by the backing pump, the main pump further improves the vacuum.
The vacuum buffer tank stabilizes system pressure. The PLC control system collects pressure signals to automatically start and stop the pump unit, achieving constant pressure; it also features overload, high-temperature, and liquid level fault alarms; the automatic drainage unit discharges condensed water.
Standalone units supply a single process equipment; central vacuum stations distribute negative pressure through a pipeline network to supply multiple workstations in the workshop simultaneously, realizing centralized negative pressure supply.

Customer FAQs

Providing professional answers to customers' core concerns.

How to choose between standalone vacuum units and central vacuum negative pressure stations?

For a few equipment workstations, choose independent complete vacuum units; for more than a dozen or more equipment in a workshop using vacuum simultaneously, prioritize central negative pressure stations for centralized management, energy saving, and reducing the number of on-site equipment.

How to distinguish and select between Roots-water ring and Roots-rotary vane units?

Prioritize Roots-water ring units for high water vapor content; choose Roots-rotary vane units for pursuing higher ultimate vacuum and dry media.

Can the integrated vacuum system be made in an explosion-proof version?

Yes, motors and electrical components are configured with explosion-proof ratings, suitable for flammable and explosive gas working conditions; medium explosion-proof parameters need to be provided.

Can the complete unit be used directly upon arrival?

Assembly, debugging, and leak testing are completed inside the factory; on-site, only process piping and power connections are needed. On-site technical guidance can be provided for some large central stations.

Can you provide solution design, drawings, and later maintenance?

Yes, we provide complete solutions and layout references based on pumping speed, vacuum degree, medium, and number of workstations, and provide original factory parts, troubleshooting, and maintenance services.
