4.2 Function
The diaphragm vacuum pump of the series MVP 015-4 is a four stage, dry compressor
vacuum pump. The pumps are positive displacement pumps with a periodic change of
size of the suction chamber produced by the movement of the diaphragm. The gas flow
causes the valves to open and close automatically. The pump units are directly connect-
ed to the drive motor.

Always place the pump on a firm, even surface.
– Where stationary installation is involved, anchor the pump on site.
Consider the load-bearing capacity of the installation site.
When installing the pump in a closed housing, ensure there is sufficient air circulation.
– Technical information given on the motor rating plate must be visible.
Installation
conditions The pump MVP 015-4 must be installed and operated under the following ambient con-
ditions:
5.2 Connecting the vacuum side
Remove locking cap on intake connection and connect vacuum pump to the appara-
tus.
The connection between the pump and the vacuum chamber should be kept as short
as possible.
– Depending on the pump type, use metallic hoses or PVC hoses with flange con-
nections.
– Separators, filters etc. may be installed upstream to protect the pump (see acces-
sories). However, please observe the loss of pumping capacity due to the conduc-
tivity of the accessories.
5.3 Connecting the exhaust side
Assemble silencer at the diaphragm head 4;
– alternatively connect exhaust line.
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.
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
High pressure in the exhaust line!
Danger of damage to the seals and danger of the pump bursting.
Install the line without shut-off valves on the exhaust side.
Do not operate the pump with excess pressure at the inlet; observe the maximum al-
lowable pressures and pressure differences.

Installation
9
5.4 Connecting to the mains power supply
The mains voltage must be determined on-site each time before the pump is installed
or moved to a different location.
Always ensure a safe connection to the protective earthing conductor (PE, protection
class III).
Motor protection
A self-locking thermal winding protector switches off the pump motor in the event of over-
heating (> 95°C).
Allow the pump to cool off several minutes.
– Pump runs-up automatically after cooling off.
WARNING
Emission of toxic substances from the exhaust!
Danger of poisoning from emitted gases or vapours, which can be detrimental to health
and/or can pollute the environment, depending on the particular application.
Comply with the applicable regulations when working with toxic substances.
Only officially approved filter systems may be used to separate and remove these
substances.
NOTICE
Excess voltage!
Danger of destroying the motor.
Power connections must comply with local regulations. Voltage and frequency infor-
mation given on the motor rating plate must correspond to the mains voltage and fre-
quency values.
To protect the motor and supply cable in case of malfunction, mains fuse protection
must be implemented.
WARNING
Danger of injury from moving parts!
After power failure or motor shutdown due to overheating, the motor may restart auto-
matically.
Secure the motor so that it cannot be switched on while any work is being performed
on the pump.
If necessary, dismantle the pump from the installation for inspection.

10
Operation
6Operation
6.1 Before switching on
Compare the voltage information on the rating plate with the supply voltage.
Check that the exhaust connection allows free flow (max. permissible pressure 1100
hPa absolute).
– 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 pump sufficiently from taking in contaminants by means of suitable precau-
tions (e.g. dust filters).
6.2 Switching on the pump
The pump can be switched on in any pressure range between atmospheric and
ultimate pressure.
The pump attains the stated values for throughput rates and ultimate pressure levels only
once the operating temperature is reached.
Connect the mains cable to the mains.
Switch on the pump with the vacuum flange closed and allow to warm up for 15 min-
utes.
Intermittentoperation
with TC via relay box
(accessory)
To prolong the life of diaphragm pumps, intermittent operations can be selected with
lesser gas throughputs of < 0.18 hPa l/s. This means that, dependent on the TMP power
take-up, the backing pump will be switched on and off. TMP power take-up is dependent
on the fore-vacuum pressure and gas throughput.
– By comparing the power take-up with an upper and a lower limit value, the relative
switch-on duration with lesser gas throughputs can be reduced to approx. 1 to 60%.
– To avoid too frequent switching on, the buffer volume in the fore-vacuum line should
amount to 0.5 liter from approx. 0.018 hPa l/s.
6.3 Switching off
The pump can be switched off in any pressure range.
CAUTION
Dangerous overpressure overload!
Mixing up the connections leads to a dangerous overpressure overload in the pump,
and the motor could be damaged.
Before commissioning, make sure that no impermissibly high pressure arises on the
pressure side.
Start pumps at a maximum pressure differential of 1000 hPa between inlet and outlet.
CAUTION
Hot surface!
Danger of burns if hot parts are touched. Depending on the operating and ambient con-
ditions, the surface temperature of the pump may rise above 70 °C.
In this case, use suitable finger guards.

Maintenance
11
7 Maintenance
7.1 Precautions
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 di-
aphragms 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
15000 operating hours.
Turn off the vacuum pump, vent to atmospheric pressure and allow to cool.
Disconnect the drive motor from the mains and secure it so that it cannot be switched
on.
Only dismantle the pump as far as necessary to carry out maintenance.
Only clean valves and diaphragms with a dry cloth; do not use alcohol or any other
detergents.
Reassemble pump in reverse order.
WARNING
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.
