3 Product description
3.1 Function
The diaphragm pump of the MVP 030-3 C DC series is a dry compressing vacuum pump with 3 pump-
ing stages. The vacuum pump is a positive displacement pump with a periodic change in suction cham-
ber size, produced by the movement of the diaphragm. The gas flow causes the valves to open and
close automatically. The pump units are directly connected to the drive motor.
Gas ballast valve
The gas ballast device is used to blend ambient air or inert gas with the process gas in the pumping
system. Increasing the air content compresses and expels a pumped gas/vapor mixture within specific
limits, without causing condensation in the suction chamber.

4. Depending on the pump type, use PVC or metallic hoses with flange connections from the Pfeiff-
er Vacuum component shop.
5. Connect the vacuum pump to the vacuum system using the vacuum connection.
5.3 Connecting the exhaust side
CAUTION
Danger of injury from bursting as a result of high pressure in the exhaust line
Faulty or inadequate exhaust pipes lead to dangerous situations, e.g. increased exhaust pressure.
There is a danger of bursting. Injuries caused by flying fragments, the escaping of high pressure, and
damage to the unit cannot be excluded.
►Route the exhaust line without shut-off units.
►Observe the permissible pressures and pressure differentials for the product.
►Check the function of the exhaust line on a regular basis.
Procedure
1. Choose a minimum diameter equal to the nominal diameter of the exhaust connection.
2. Depending on the pump type, use PVC or metallic hoses with flange connections from the Pfeiff-
er Vacuum component shop.
3. Route the piping downwards from the vacuum pump, to prevent condensate return.
4. Support or suspend the piping to the vacuum pump so that no piping system forces act on the
vacuum pump.

Property damage on the electronics
Separating all plug-and-socket connections within the bus system with voltage supply switched on
may lead to the destruction of electronic components.
►Always disconnect the voltage supply before removing the connecting plug.
►After switching off the power supply pack, wait until the residual load has dispersed completely
before disconnecting the plug-and-socket connection.
