DRYVAC DV 300
Dry compressing screw vacuum pump
Smart engineering for today and tomorrow: our network-capable DRYVAC series delivers cutting-edge performance and efficiency, even when the going gets tough.
This series of dry compressing screw-type vacuum pumps is engineered for the connected age. Packed with intelligent features and functions, all DRYVAC models offer seamless connectivity, networked control and superior efficiency.
DRYVAC pumps boost your productivity, minimize your carbon footprint, and lower your costs. Plus, thanks to an integrated smart service concept, they virtually look after themselves.
Connected, efficient, reliable – smarter with Leybold.
Built-in intelligence for industrial applications
Seamless connectivity & networkingSeamless connectivity & networking
Fieldbus and PLC compatibility allow for connectivity to other devices in a network for real-time communications and control. Direct control is also possible via a computer or handheld device. Support for various fieldbus protocols ensures maximal flexibility. Protocol support for Profibus, Ethernet/IP, ProfiNet and EtherCAT as option.
Intelligent energy consumptionIntelligent energy consumption
The low constant power consumption delivers siginificant energy efficiency. The advanced self-regulating feature, only consumes the power the pump actually needs, saving costs and reducing your carbon footprint. DRYVAC pumps are more cost-efficient and greener than similar models operating in the low-pressure range (<10 mbar).Smart service conceptSmart service concept Continuous performance monitoring made possible via an integrated frequency converter and three independent sensors. Should abnormal conditions such as overheating be detected, DRYVAC pumps can communicate them quickly and efficiently via fieldbus. Preset parameters enable plug-and-play operation, without additional installation.DRYVAC pumps also feature minimal maintenance and easy cleaning of water cooling channels thanks to a non-jacketed design.Characteristics Hermetically sealed screw vacuum pump with integrated frequency converterSimple mechanical and electrical integrationIntegrated protection functions of temperature, exhaust pressure and power consumption monitoringSmall footprint due to compact designLow energy consumption achieved through optimized rotor geometry and innovative motor design with efficiency class IE3Tolerant to dust ingressExcellent condensable gas (water vapor) performanceHigh pumping speed also at high intake pressuresTechnical data Max. pumping speed 280 m3/h 165 cfm Ultimate pressure (w/o gas ballast) 0.01 mbar 0.008 Torr Permissible ambient temperature 5 to 50 °C Noise level with silencer at ultimate pressure 65 dB(A) Relative ambient atmospheric humidity 90%, non-condensing Max. installation height Up to 2000 m above sea level Cooling Water Cooling water temperature range 5 to 35 °C Cooling water nominal flow 8 l/min Mains voltage 50/60 Hz 200-240 V ±10% or 380-460 V ±10% Rated power 50/60 Hz 7.5 kW Power consumption at ultimate pressure 4.5 kW Bearing lubricant LVO 210 synthetic oil Protection class IP54 Intake connection DN 63 ISO-K Discharge flange DN 40 ISO-KF Weight, approx. 370 kg Dimensions (W x H x D) 1110 mm x 613 mm x 478 mmMonitoring Pressure switch on exhaust side (1.2 bar abs.)Temperature pump housingTemperature motorCurrent limits through frequency converterEquipment Integrated frequency converterElectro pneumatic gas ballast valve 24 VDCPurge gas valve 24 VDC
