Oil-lubricated single-stage vacuum pump DVP LC 2 / DVP LC 4

The robust construction of the LC 2 and LC 4 models, along with their advanced oil management features, ensures exceptional operation and minimizes the need for frequent maintenance. The oil check valve plays a crucial role in maintaining vacuum integrity by automatically preventing oil from flowing back into the vacuum chamber when the pump stops. This is essential for applications where a constant and reliable vacuum source is required, such as in medical and dental procedures, where any interruption can lead to complications.

In addition, the FKM gaskets provide a superior seal, resulting in improved pump efficiency and safety. These gaskets are resistant to chemical erosion and temperature fluctuations, making them ideal for use in environments where aggressive materials or extreme conditions occur, such as in the screen printing industry and when mixing resins. The addition of an exhaust cleaner and gravity oil recovery valve further increases the operational hygiene and environmental friendliness of these pumps by minimizing emissions and ensuring a cleaner work area.

DVP’s LC 2 and LC 4 pumps come standard with:

• Oil check valve, integrated into the structure, which guarantees perfect isolation of the system when the pump is stopped in vacuum
• FKM gaskets, which guarantee a perfect seal and a long service life
• Exhaust cleaner
• Gravity oil recovery valve
• Rotor and pump body with the special NPO anti-oxidation treatment, which increases their hardness and makes them resistant to oxidation generated by drawing flows with high percentages of condensables
• Thermal protection (1~ only)

Main application areas: vacuum packaging machines; surgical aspirators for dentists and hospitals; mixers and dosing resins for dentists; screen printing machines; automatic sheet feeding in binding machines; wood presses; wall drilling machines for the construction industry.
