Read and understand instruction manuals
and observe the warnings before installation,
operation, service and maintenance.
Not following the instructions can result in
serious accidents.
In order to make the information clear only foreseeable conditions
have been considered. No warnings are given, therefore, for
situations arising from the unintended usage of the machine and its
tools.

This manual is designed for operators and service
engineers working with the Alfa Laval separator
MAB 103B-24.
For information concerning the function of the
separator, see ‘‘3 Separator Basics” on page 17,
and ‘‘4 Operating Instructions” on page 31.
If the separator has been delivered and installed
by Alfa Laval as part of a processing system, this
manual is a part of the System Manual. In this
case, study carefully all the instructions in the
System Manual.
In addition to this Separator Manual a Spare
Parts Catalogue, SPC is supplied.
This Separator Manual consists of:
Safety Instructions

the separator. Not following the safety instructions
can cause accidents resulting in damage to
equipment and serious injury to personnel.
Separator Basics
Read this chapter if you are not familiar with this
type of separator.
Operating Instructions
This chapter contains operating instructions for
the separator only.

2 Safety Instructions
The centrifuge includes parts that rotate at high
speed. This means that:
xKinetic energy is high
xGreat forces are generated
xStopping time is long
Manufacturing tolerances are extremely fine.
Rotating parts are carefully balanced to reduce
undesired vibrations that can cause a breakdown.
Material properties have been considered
carefully during design to withstand stress and
fatigue.
The separator is designed and supplied for a
specific separation duty (type of liquid, rotational
speed, temperature, density etc.) and must not be
used for any other purpose.
Incorrect operation and maintenance can result in
unbalance due to build-up of sediment, reduction
of material strength, etc., that subsequently could
lead to serious damage and/or injury.
The following basic safety instructions therefore
apply:
xUse the separator only for the purpose
and parameter range specified by
Alfa Laval.
xStrictly follow the instructions for
installation, operation and maintenance.
xEnsure that personnel are competent and
have sufficient knowledge of maintenance
and operation, especially concerning
emergency stopping procedures.
xUse only Alfa Laval genuine spare parts
and the special tools supplied.

Disintegration hazards
xWhen power cables are connected,
always check direction of motor rotation.
If incorrect, vital rotating parts could
unscrew.
xIf excessive vibration occurs, stop
separator and keep bowl filled with
liquid during rundown.
xUse the separator only for the purpose
and parameter range specified by
Alfa Laval.

xCheck that the gear ratio is correct for
power frequency used. If incorrect,
subsequent overspeed may result in a
serious break down.
xWelding or heating of parts that rotate
can seriously affect material strength.
xWear on the large lock ring thread must
not exceed safety limit. I-mark on lock
ring must not pass opposite I-mark by
more than specified distance.
xInspect regularly for corrosion and
erosion damage. Inspect frequently if
process liquid is corrosive or erosive.
