Details

PVL15/PVL35

Ultimate pressure:≤ 0,5 and ≤ 20 mbar

Pumping speed:17÷42 m³/h

The PVL 15 and PVL 35 pumps are single-stage rotary vane lubricated pumps with oil recirculation.
The flanged electric motor is connected by means of an elastic coupling.
An integrated control 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 ballast prevents condensation inside the pump when small quantities of steam are sucked.

The PVL 15 and PVL 35 pumps are suitable for the evacuation of closed systems or to operate at a constant vacuum included in the following range:

PVL 15 – PVL 35 from 0,5 to 300 mbar (absolute)

PVL 15 B – PVL 35 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 / vacuostats
Pressure gauges / pressure switches
Thermostat
Minimum oil level switch
