Installation
Pumps with purge gas valve (MAG (W) 1500 CT,
W 2200 C, W 2800 C/CT, W 3200 CT)
The MAG is equipped with a purge gas and venting valve. It is controlled
by the MAG.DRIVE
digital
.
The purge gas and vent valve
■ regulates the flow of purge gas, at supply pressures of between 1.5 and
6.0 bar (absolute), to the pump, keeping pressure at a constant value
and
■ provides for safe pump venting.
The flow of purge gas into the pump keeps aggressive or corrosive media
and dust from entering the motor and bearing area.
Refer to Figure 39 for details on the design and function of the purge gas
and vent valve assembly.
Attach the purge gas hose to the nipple and secure with a hose clamp.
Set purge gas pressure for a value of 1.5 to 6.0 bar, absolute.
Use in the purge gas supply system only valves which can handle both the
low purge gas flow and the much greater venting gas flow.
Purge gas inlet pressure exceeding 10 bar can damage or destroy
the purge gas and vent valve.
With no voltage applied the purge gas and vent valve is closed.
The purge gas and vent valve will be open when switching on the
MAG.DRIVE
digital
