EM 4 - 8 Ultimate pressure: ≤ 2 and ≤ 20 mbar Pumping speed: 4÷10 m3/h
The EM 4 and EM 8 are single-stage rotary vane lubricated pumps with oil recirculation.
The rotor is keyed directly onto the motor shaft.
The oil tank is provided with a system for separating the oil mists from the exhaust air.
The gas ballast, except for EM4, prevents condensation inside the pump when small quantities of steam are sucked.
The EM 4 and EM 8 pumps are suitable for the evacuation of closed systems or to operate at a constant vacuum included in the following range:
EM 4 – EM 8 from 2 to 300 mbar (absolute)
EM 4 B - EM 8 B from 20 to 850 mbar (absolute)
ACCESSORIES
The following accessories are useful for the installation and for the control of the pump operation parameters:
- External suction filter
- Vacuum gauges
