Installation, Operating and Maintenance Instruction

3. Description

3.1 Models

MPB Design: Multi-stage block pump with vertical
shaft, drive-side grease-lubricated rolling bearing
(=motor bearing), radial medium-lubricated slide
bearing in the intake casing of the pump.
MPV Design: Vertical multi-stage pump with its own
axial bearing with grease lubrication and relubrication
mechanism; standard motors as per IEC, design V1,
output from 55 (11) kW to 355 kW; power transfer via
elastic
coupling;
radial
bearing in the intake casing of the pump; bearing and
shaft seal replaceable without disassembly of the
pump body.
Installation position: Shaft vertical. Installation
positions deviating therefrom must be approved by the
manufacturer.
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

MPB Design: Drive-side in the rolling bearings of the
motor. The bearings have lifetime grease lubrication
so that no maintenance is required.
MPV Design: Drive-side: Pressure-side angular ball
bearing (fixed bearing) with relubrication mechanism
(lubrication nipple)

MPB and MPV designs:
Intake-side: Medium-lubricated slide bearing in the
intake casing of the pump.
The pump-side slide bearing is lubricated by the
pumped medium.
