Overview

The Laibao VARODRY oil-free screw pump VD65 ensures the required operating pressure, short section emptying, and final system availability and durability, making it particularly suitable for wet or dusty processes. VARODRY is easy to install and connect, and can be easily integrated into new or existing systems. VARODRY is a 100% air-cooled pump that does not require cooling water. Leybold's developers used fewer, validated mechanical parts and components in their designs. VARODRY enables its users to achieve low maintenance requirements, oil-free emissions, and low operating noise in daily operations. In addition, the pump is dry and clean

Detailed introduction:

Dry screw vacuum pumpVARODRY seriesThere will be no phenomenon of lubricating oil coming into contact with the pumping medium, so an oil-free vacuum can be generated. According to application requirements, different types and working principles of dry compression vacuum pumps can be provided: diaphragm pump DIVAC, vortex pump SCROLLVAC, screw pump VARODRY, SCREWLINE, DRYVAC, and LEYVAC.

We are a professional enterprise that sells imported vacuum pumps and supporting equipment, with business radiating to the East China region. We have established good cooperative relationships with customers in the vacuum application industry in the Yangtze River Delta region. With our vacuum technology team, the company has formed a system that provides pre-sales technical consultation, system configuration, reasonable selection, equipment installation, commissioning, and maintenance services to customers. The company has gained recognition and praise from customers for its vacuum pump technology, product quality, and after-sales service.

The company has strong technical capabilities and can undertake various vacuum engineering projects. The company sells imported vacuum products and conducts professional repairs and maintenance.

VARODRY VD65

Eliminate the low process efficiency caused by vacuum.

The new VARODRY vacuum pump series is designed and produced by Leybold, Germany, specifically for industrial processes. Using a VARODRY vacuum cleaner can easily, efficiently, reliably, and dry relieve headaches.

Efficient pumping

The VARODRY rotor design has been optimized to provide high efficiency.

Pull speed

VARODRY provides competitive pumping speeds across the entire pressure range, with terminal pressures less than 0.01 mbar. It can operate continuously at any inlet pressure.

Power efficiency index

VARODRY can quickly evacuate to a range of 10-2 mbar.

VARODRY has been optimized to address many challenges in industrial applications:

Repeat rapid cycle:VARODRY provides quick evacuation. The pump can withstand atmospheric pressure shocks and repeated vacuum cycles.

Dust/Particle Handling:The principle of pump screw can provide excellent performance to handle small, dry dust particles without wear. If a large amount of dust needs to be processed, various dust filters can be provided.

Steam treatment:Due to its optimized temperature curve and built-in gas ballast, VARODRY has vapor resistance, avoiding internal condensation and corrosion.

Active gashandleSteam (such as hydrocarbons) typically reacts inside hot dry pumps and accumulates internal coatings, leading to pump jamming.

The moderate temperature inside VARODRY actually eliminates this risk.

Liquid handling:Due to the free flow of liquid from the pump, VARODRY can handle droplets or even liquid clumps.

Improve the efficiency of your machine. VARODRY makes it easy.

Operating costs

Due to 100% air-cooled drying, VARODRY only consumes electricity and does not require additional payment for cooling water supply or replacement and disposal of oil/oil filters. Its low power consumption will save a lot of operating costs.

Cost of Ownership Example: Composite Materials (Wind Power Plant)

Compared to oil sealed rotary vane pumps, VARODRY will save over 600 euros in operating costs annually!

User Maintenance

The belt can be easily replaced in less than 30 minutes. The exchange interval depends on the individual application, but is usually greater than 1 year. Provide belt replacement kit and maintenance tool kit.

VARODRY reduces your maintenance and service requirements

Only two vulnerable components (belt and bearing) are needed, and with minimal effort, the pump can maintain good performance and extend the normal operation time of the equipment.

Laibao Service

Bearings can be replaced on-site by trained maintenance technicians. The typical bearing life is>3 years. Pump maintenance can be carried out at one of the many Leybold global service centers.

To ensure the highest normal operation time of the factory, Leybold provides the fastest "pump replacement". Our backup pool also provides fixed costs for exchange pumps, so your production always keeps running.
