Installation, Operating and Maintenance Instruction
3. Description
3.1 Models
Design MP: Horizontal shaft with bearings at both
ends, drive end at discharge side (standard), rotation
clockwise with suction branch left and discharge
branch radially upwards. Grease lubrication.
Optional:
Suction branch right or radially upwards,
discharge branch left or right, drive-end at suction side
(rotation anti-clockwise).
Design MPA: Endsuction
radially upwards. Drive end at discharge side. Thrust
bearing at drive side, grease lubrication, medium
lubricated slide bearing between first and second
stage.
Optional:
Discharge branch left or right.
MPAI Design: As the MPA design, but also with an
inducer.
The pumps are designed as modular systems and
can, therefore, be delivered in many variants (e.g.
different materials, shaft sealings, different kinds of
lubrication, cooling / heating, a.s.o.).
The permitted application conditions and design
details of the delivered pump are shown in the
attached data sheet and / or order confirmation.
3.2 Shaft Sealing
Basically there are two kinds of shaft sealing: the
packing and the mechanical seal, whereas, there
again are many variants of both kinds. At the data
sheet and / or the order confirmation the shaft sealing
type of your pump is shown.
Instructions for packing a gland can be found in
Section 7.3 and instructions for installation and
operation
of
mechanical
"Disassembly of the Pump and Repair".
Further details about packing and mech. seals,
as well as the therewith connected accidental
dangers, you can find in chapter 6.6 and in
chapters 7.2 and 7.3.
In areas endangered to explosion the use of
pumps with packing is forbidden!
3.3 Bearings
Design MP: Bearings at both ends; thrust bearing at
discharge
side,
ball
Lubrication: Grease lubrication (standard design) with
relubricating mechanism (lubricating nipple).
Design MPA, MPAI: Thrust bearing at discharge side,
medium lubricated slide bearing between first and
second stage at suction side.
Lubrication: Grease lubrication (standard design) with
relubricating mechanism (lubricating nipple).
