Product description
4.2 Function
The diaphragm vacuum pumps of the series MVP 070-3 are three stage and those
of the MVP 040-2 series are two stage, dry compressor vacuum pumps. The pumps
are positive displacement pumps with a periodic change of size of the suction
chamber produced by t he movement of the diaphragm. The gas f low causes the
valves to open and close automatically. The pump units are directly connected to
the drive motor.

Danger of damage to the seals and danger of the pump bursting.
! Install the line without shut-off valves on the exhaust side.
! Pumpe nicht mit Überdruck am Einlass betreiben; max. zulässige Drücke und Druck-
differenzen beachten.
! Choose the cross-section of the exhaust line to be at least the size of the nominal
connection diameter of the vacuum pump's exhaust connection.
! Piping to the pump must be suspended or supported.
–Physical forces from the piping system must not be allowed to act on vacuum
pumps.
! Lay piping from the pump sloping downward so that no condensate can flow
back into the pump; otherwise fit a condensate separator.
–If an air trap is created in the system, then a device for draining condensation
water must be provided at the lowest point.
CAUTION

6Operation
6.1 Before switching on the pump
! Compare the voltage information on the rating plate with the mains voltage.
! Check that the exhaust connection allows free flow (max. permissible pressure
1.1 b ar a bso lu te) .
–Activate the shut-off valves in such a way that they open before or at the same
time as the pump is started.
! Protect the p ump sufficien tly from taking in contaminants by means of suitable
precautions (e.g. dust filters).
Dangerous overpressure overload!
Mixing up the connections leads to a dangerous overpressure overload in the pump,
and the motor could be damaged.
! Before commissioning, it is imperative that you ensure that the pressure does rise
above the maximum permissible pressure on the pressure side.
! Start pumps at a maximum pressure differential of 1 bar between inlet and outlet.
Operation
CAUTION
6.2 Switching on the pump
The pump can be switched on in any pressure range.
No special precautions are necessary when pumping dry gases. In order to attain
the lowest possible final pressures, the gas ballast valve should be closed.
The pump attains the stated values for throughput rates and final pressure levels
only once the operating temperature is reached (after approximately 15 minutes).
! Switch on the pump with the vacuum flange closed and allow to warm up for 15
minutes.
Hot surface!
Danger of burns if hot parts are touched. Depending on the operating and ambient
conditions, the surface temperature of the pump may rise above 70 °C.
! In this case, use suitable finger guards.
CAUTION
13
Operation
6.3 Pumping condensable vapours
Should the process gases contain condensable gases present at high percentages,
the vacuum pump must be operated with a gas ballast (i.e. with an open gas ballast
valve).
Reactive, explosive or otherwise dangerous mixtures!
Uncontrolled gas inlet at the gas ballast valve can result in dangerous mixtures.
! By implementing the required safety measures, the user must prevent potentially ex-
plosive mixtures from occurring in the inside of the pump and from being ignited in
the event of a diaphragm crack by mechanically produced sparks, hot surfaces or
static electricity.
! If necessary, use inert gas for ventilation and gas ballast supply.
Bad final vacuum and damage to the pump!
Danger of condensation and a reduced final vacuum during operation without a gas
ballast or in case of insufficient supply of flushing gas.
! Only pump vapors when the pump is warm and the gas ballast valve is open.
! When the process has been completed, allow the pump to continue running for
about 30 minutes at atmospheric pressure with the gas ballast open.
WARNIN G
NOTE
Gas ballast valve Letting in gas ballast improves the discharge of condensate, and the pump
achieves the specified final vacuum more quickly.

6.4 Switching off
14
The pump can be switched off in any pressure range.
7Maintenance
7.1 Precautions
Pump parts may be contaminated from pumped media!
Danger of poisoning due to contact with harmful substances.
! Decontaminate the pump before carrying out any maintenance work.
! In the event of contamination, take suitable safety precautions to prevent your health
from being harmed by any dangerous substances.
The valves and the diaphragms are wear parts. If the rated ultimate vacuum is no
longer achieved, the pump interior, the diaphragms and the valves must be
cleaned and the diaphragms and valves must be checked for cracks or other damage.
Depending on individual cases it may be efficient to check and clean the pump
heads on a regular basis. In case of normal wear the lifetime of the diaphragms and
valves is > 10000 operating hours.
! Allow the pump to cool to a safe temperature.
! Only dismantle the pump as far as necessary in order to repair defects.
! Use only alcohol or similar agents for cleaning pump parts.
! Re-assemble pump in reverse order.
