Oil-Free Screw Vacuum Pump
Oil-free screw vacuum pump utilizes advanced screw technology and an efficient drive system to achieve outstanding vacuum performance and low operating costs. This pump is equipped with temperature control features and demands minimal maintenance with long service intervals, making it a reliable, energy-efficient, and high-vacuum option. It operates without any oil lubrication, ensuring that it does not contribute to environmental pollution. With its low noise levels and compact design, oil-free screw vacuum pump is easy to install and maintain, making it an ideal choice for applications that require a clean, oil-free environment.
- Power
15-250kW
- Pressure
-10kPa to -70kPa
- Volume flow
2.05-341.25m³/min
- Simple and compact structure: screw, pump body, end cover, seals and other components with opposite rotation.
- Dry operation, without any working medium, so no oil pollution, no sewage discharge, significant effect of energy conservation and emission reduction.
- No friction in the original suction chamber: there is a certain gap between the screw and the pump body.
- High vacuum: A single screw vacuum pump can replace the three-stage Roots pump water ring vacuum unit.
- Low noise: about 80 decibels under normal circumstances.
- Suitable for pumping condensable gases (e.g. water vapour).
- Pumping from the atmosphere to the limit pressure of 5Pa can be solved with only one pump.
- Dry operation makes it easier to recover lysates.
- It can form a vacuum system with Roots pump to obtain higher ultimate vacuum degree and increase pumping speed.
- The inlet is equipped with a one-way globe valve to prevent gas backflow.
- The air outlet is equipped with a standard silencer, no need for customers to buy another.
- The unique nano-permeable alloy technology solves the problem that the traditional Teflon coating easily falls off and improves the corrosion resistance and reliability of the pump operation.
- The air inlet is equipped with online purge device (optional), which can purge and clean the pump chamber when it is shut down.
