The EU 160, EU 205, EU 300 and EU 650 HWT are single-stage rotary vane lubricated vacuum pumps with oil recirculation.
The flanged electric motor is coupled by an elastic coupling.
An integrated check valve prevents the oil from coming back and the return of air into the chamber to be pumped down during the stop phase.
The oil tank is provided with a system for separating the oil mists from the exhaust air; the separated oil is automatically recovered from the pump.
The circuit and the increased gas ballasts prevent condensation inside the pump when large quantities of vapours are sucked.
The EU 160, 205, 300 and 650 HWT pumps are suitable for the evacuation of closed systems or to operate at a constant vacuum included in the following range:
EU160 HWT from 0,8 to 400 mbar (absolute)
EU205 – 300 – 650 HWT from 0,8 to 850 mbar (absolute)
The following accessories are useful for the installation and for the control of the pump operation parameters:
- External suction filter
- Vacuum gauges / vacuostats
- Pressure gauges / pressure switches
- Minimum oil level switc
