90 m³/h Two-stage Oil Sealed Rotary Vane Vacuum Pump DRV90 RAL 7047

DRV90 90m³/h Two-Stage Oil Sealed Rotary Vane Vacuum Pump

When the ambient temperature range is under 40℃, the air inlet pressure is less than 1300Pa, which allows long-term continuous operation. However, when pumped gas relative humidity is above 90%, it should open the gas ballast valve.

Features&Benefits

*Using a non-spring rotary vane to achieve low noise, low vibration, and long service life.

*A Built-in oil check valve is used to avoid the oil return phenomenon.

*A Built-in forced-fed oil pump is used to ensure the long-term continuous operation of the pump at atmospheric pressure.

*The use of air cooling, oil cooling, water cooling, and other cooling methods to ensure a good cooling effect, and make the long-term stable running of the pump and the stable pumping performance.

*Reasonable structure has the advantages of easy assembly and disassembly as well as fast and easy maintenance.
