The oil lubricated vacuum pumps from the EU H series allow to achieve greater capacity and higher vacuum levels.
At 1 mbar the pumping speed of the H series with closed gas ballast valve is 80% higher than the one of an equivalent EU standard version.
The EU 107 H, EU 300 H and EU 650 H are single-stage rotary vane lubricated pumps with oil recirculation.
The flanged electric motor is coupled by an elastic coupling.
The cooling is ensured by a powerful centrifugal fan for the EU 107 H while it is ensured by an air/oil heat exchanger with a centrifugal fan for the EU 300 H and EU 650 H models.
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 gas ballasts prevent condensation inside the pump when small quantities of steam are sucked.
The EU 107 H, EU 300 H and EU 650 H pumps are suitable for the evacuation of closed systems or to operate at a constant vacuum included in the following range:
EU 107 H – EU 300 H – EU 650 H from 0,1 to 850 mbar (absolute)
ACCESSORIES
The following accessories are useful for the installation and for the control of the pump operation parameters:
