The unique design of Lide's dual anti return oil structure and automatic anti return oil valve effectively avoid and solve the problem of oil return in emergency situations, so that your equipment will not be contaminated due to oil return.
Forced lubrication, built-in gear pump and constant pressure oil supply mechanism for forced oil supply, stable and reliable operation even under high suction pressure.
Multi level pneumatic design to meet customers' vacuum requirements and water vapor processing capabilities.
Double anti backflow structure, automatic anti backflow valve, more reliably protects your vacuum system from oil contamination after shutdown
Multi level pneumatic design to meet customers' vacuum requirements and water vapor processing capabilities
The integral cylinder structure has higher precision, and the verified rotary blade technology makes the performance more stable
Built in gear pump and constant pressure oil supply mechanism for forced oil supply, capable of stable and reliable operation even under high suction pressure
1. Oil mist filter: recovers oil mist and can make the pump quieter (optional)
2. Vacuum pump oil: delivered once with the pump (needs to be replaced regularly)
3. Clamp and interface: standard KF25 or KF40 (please inform the business personnel in advance for specific connectors)
4. One copy of the product manual (please read carefully before use)
Corrosion resistant LDV-C series: When your usage environment has mild corrosive gases such as acidity, strong oxidation, and water vapor, you can choose the LDV-C series vacuum pump. We use stainless steel springs, fluororubber seals, corrosion-resistant pump bodies, etc. to ensure that our products can operate stably and reliably in this environment. (It is recommended to choose Lide dry oil-free screw vacuum pump for strong corrosive environments)
Explosion proof series: suitable for flammable and explosive environments, with optional explosion-proof vacuum pump accessories and bodies to meet the vacuum requirements in explosion-proof environments.
