Lubrication of Roller Bearings
Standard: grease lubrication with grease nipples.
Grease lubricants to be of Lithium Base Grade 2.
The bearings are already filled with grease and are thus
ready for use.

3. TRANSPORT, HANDLING, STORAGE
3.1 Transport, Handling
• Check the pump/pump unit immediately
upon delivery/receipt of shipment for
damage or missing parts.
• The pump/pump unit must be transported
carefully and by competent personnel.
Avoid serious impacts.
• Keep the pump/pump unit in the same
position in which it was supplied from the
factory. Take note of the instructions on the
packaging.
• The intake and discharge side of the pump
must be closed with plugs during transport
and storage.
ATTENTION: DISPOSE OF ALL
PACKING MATERIALS IN
ACCORDANCE WITH LOCAL
REGULATIONS.
• Lifting devices (e.g. fork-lift truck, crane, crane device,
pulleys, sling ropes, etc.) must be sufficiently strong.
• The pump/pump unit may only be lifted by solid
points such as the casing, flanges or frame. The
illustration above shows the correct method of carrying
by crane.
Do not stand underneath suspended loads; take
note of the general regulations on prevention of
accidents.
The pump/pump unit must be secured against tipping
over and slipping until it has been fixed in its final
location.
3.2 Storage
Pump or pump units that are stored for a long time
before use must be protected against moisture,
vibrations and dirt (e.g. by wrapping in oil paper or
plastic sheeting). Pumps must basically be stored in a
place where they are protected from the weather, e.g.
under cover. During this time, all suction and discharge
branches and all other intakes and outlets must be closed
with dummy flanges or plugs.
Preservation
On storing the pump longer than 3 months (depends on
order): Special preservation has been used for shipment
prep. The product used for that must be removed from
the unit before the first normal operation.
4. INSTALLATION, OPERATION
4.1 Assembly and Connection of Pump
MPVN type pumps must be bolted to a fixed subframe
(e.g. concrete foundation, steel plate, steel beam, etc.).
The subframe must withstand all loads that arise during
operation. The size of the subframe and the location and
size of the recesses for the foundation anchors are given
in the dimension drawing, which is binding.
ATTENTION: SUFFICIENT SPACE MUST BE
PROVIDED FOR MAINTENANCE
AND REPAIR WORK, ESPECIALLY
FOR REPLACING THE DRIVE
MOTOR OR THE COMPLETE
PUMP UNIT. THE MOTOR FAN
MUST BE ABLE TO TAKE IN
ENOUGH COOL AIR, AND THE
INTAKE GRILLE MUST THEREFORE
BE AT LEAST 10 CM AWAY FROM
ANY WALL, ETC.
To prevent vibrations being transmitted to adjoining
components, the foundation should be laid on a suitable
insulating base (panels providing insulation against
structure-borne sound or vibration panels).
ATTENTION: THE SIZE OF THESE INSULATING
PANELS WILL VARY, DEPENDING
ON CIRCUMSTANCES, AND
SHOULD THEREFORE BE
DETERMINED BY AN
EXPERIENCED SPECIALIST.
Concrete foundations must be completely set and the
surfaces must be smooth before the pump unit is mounted.
Put pump unit onto the foundation and, if necessary, level
vertically with the help of thin sheet-metal panels (with spirit
level). Tighten foundation anchor evenly and firmly.
The alignment must be carried out with the utmost
care and attention, so that the unit will operate
without failure. If you do not pay attention to this
hint you will lose your warranty!
4.2 Installation and Alignment of Coupling
Make sure that nobody can start the motor
when work is being carried out on the
coupling. In accordance with the Accident
Prevention Regulations, the pump unit may
only be operated when the coupling guard is mounted.
• Before starting installation, carefully clean shaft ends
and coupling components.
• Pull coupling hub onto motor shaft end. The coupling
may be heated beforehand in an oil bath to approx.
100°C. The motor hub will need to be mounted flush
to the motor shaft.
• The motor coupling hub will have an interference fit
and the pump coupling hub will have a clearance fit.
The clearance allows the pump hub to be adjusted on
the pump shaft. Keep pump hub loose for adjusting the
elastomer element.
• Place half of the coupling elastomer element around
the hubs and secure with self-locking capscrews.
