The wastewater treatment industry has dual requirements for production continuity and corrosion resistance. Traditional oil-lubricated vacuum pumps generate oil mist during operation, posing a risk of contaminating water bodies and affecting treatment chemicals and effluent quality. They also require regular oil changes and maintenance, affecting continuous treatment. Leynow oil-free vacuum pumps adopt an oil-free lubrication structure to prevent oil contamination from entering the vacuum system from the source, and have become the preferred configuration for multiple processes such as vacuum evaporation and concentration, MVR systems, vacuum filtration and dewatering, sludge dewatering, and wastewater vacuum degassing.
Challenges Faced by the Industry
The requirements of wastewater treatment for vacuum systems are not just about "pulling a vacuum", but more importantly, cleanliness, corrosion resistance, and resistance to continuous operation. In practical applications, customers often encounter the following types of problems:
Risk of Oil Contamination
Oil-lubricated vacuum pumps generate oil mist during exhaust, which may contaminate water bodies and treatment chemicals, affecting effluent quality and evaporation concentration effects.
Pumping Speed Cannot Keep Up with Treatment Capacity
Evaporation concentration and MVR systems have large treatment capacities. Insufficient pumping speed of the vacuum pump will lead to decreased evaporation efficiency and affect treatment capacity.
Corrosion and Unstable Continuous Operation
Wastewater treatment often requires 24-hour continuous operation, with water vapor and acid-base corrosive gases. Pump body overheating or vacuum fluctuations directly affect treatment effects.
High Maintenance Costs
Vacuum pump oil needs to be replaced regularly. Under working conditions with water vapor, the oil is prone to emulsification and deterioration, and downtime for maintenance affects overall treatment efficiency.
Leynow Wastewater Industry Solutions
Targeting the actual working conditions of the wastewater industry, Leynow provides overall vacuum solutions centered on oil-free vacuum pumps, forming a complete service closed loop from equipment selection and installation and commissioning to post-maintenance.
Clean and Oil-free Vacuum Acquisition Method
Oil-free vacuum pumps adopt a self-lubricating structure, and the inner wall of the cylinder is specially treated. They do not generate oil mist or exhaust gas, preventing lubricating oil from entering the vacuum system, meeting the requirements of wastewater treatment for cleanliness and effluent quality.
Selection Solutions Matched to Treatment Processes
Based on the evaporator type, MVR system pumping volume, vacuum degree requirements of filtration equipment, and treatment water volume, professional engineers provide selection suggestions to avoid efficiency and lifespan issues caused by "using a large pump for a small job" or "overloading a small pump".
Guarantee of Stable and Continuous Operation
For wastewater treatment production lines operating continuously for 24 hours, the heat dissipation and anti-corrosion structures are optimized to reduce the risks of pump body overheating and water vapor corrosion, maintain stable vacuum degree output, and ensure evaporation and dewatering efficiency.
Full-cycle Service and Parts Guarantee
Providing installation and commissioning, regular follow-up visits, and maintenance contract services. Repair parts are Leynow original genuine parts. All repair projects come with a 12-month warranty to reduce unplanned downtime.
