Ultimate pressure:
≤ 2 and ≤ 20 mbar
Pumping speed:
28÷51 m3/h

 

The EM 28 and EM 40 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 prevents condensation inside the pump when small quantities of steam are sucked.

The EM 28 and EM 40 pumps are suitable for the evacuation of closed systems or to operate at a constant vacuum included in the following range:

EM 28 - EM 40 from 2 to 400 mbar (absolute)
EM 28 B - EM 40 B from 20 to 850 mbar (absolute)
