SAFETY
ICS Wear Group Inc. slurry pumps have been designed for safe and reliable operation. A pump is a pressure-
containing device with rotating parts that could be hazardous. Operators and maintenance personnel must
realize this and follow the necessary safety measures. All statutory requirements relating to this equipment must
be complied with at all times and site safety procedures strictly adhered to.
ICS shall not be liable for damage or delays caused by a failure to observe either the instructions in this manual
or the usual industry safety procedures.
CAUTION
Never completely restrict the discharge flow. It may result in adverse temperature increase and possible
explosion (as applicable to all centrifugal pump brands).
Never apply heat to the impeller to assist removal from shaft. Heating may result in shattering the impeller
RESULTING IN INJURY OR EQUIPMENT DAMAGE
Direction test driven WITHOUT belt drives or couplings fitted. The impeller is threaded and incorrect rotation
may cause personnel injury or equipment damage.
If pump is operating with a very hot or very cold liquid, gradually change pump temperature to prevent damage
by thermal shock. Thermal shock may cause personnel injury or equipment damage
NOTE
Proper alignment is essential for long pump life.
GENERAL PRECAUTIONS
• Warning: Personal injuries will result if procedures outlined in this manual are not followed.
• Never work on the pump set with the power connected.
• Never work on the pumpsets without the appropriate work tags (eg ‘Danger Tags’) fitted in compliance
with site safety procedures.
• Never operate pump without drive guard correctly installed.
• Never operate pump beyond the rated conditions for which the pump was sold.
• Never run pump below the recommended minimum flow or when dry.
• Never operate pump without safety devices installed.
• Never operate pump with discharge valve closed.
• Never use heat to disassemble pumps due to risk of explosion from trapped liquid.
• With the pump disconnected from the driver, check the motor rotation. Incorrect motor rotation can
cause the impeller to back off of its threads and rupture the casing. It may also cause personal injury.
WHERE AUXHILIARY EQUIPMENT IS ASSOCIATED WITH A PUMP (eg. MOTORS, DRIVE BELTS,
DRIVE COUPLINGS, SPEED REDUCERS, VARIABLE SPEED DRIVES, ETC), ALL RELEVANT
INSTRUCTION MANUALS SHOULD BE CONSULTED, AND RECOMMENDED PROCEDURES
IMPLEMENTED, DURING INSTALLATION, OPERATION AND MAINTENANCE OF THE PUMP
SYSTEM.

1. INTRODUCTION
This manual is applicable for ICS Heavy Duty Mill Master slurry pumps from the 6x4 to 12x10. The Mill
Master line of pumps feature a wide choice of replaceable abrasion resistant metal or molded elastomer casing
liners and impellers, which are all interchangeable within a common casing assembly.
The pumps may be fitted with a range of seal types depending on the particular duty requirements: a water-
flushed packed gland seal (standard); an expeller; or an ICS Patented Mechanical Seal.
If problems are experienced during pump operation, reference should be made to the ICS Fault Detection Chart.
If operating problems are not rectified by following instructions in the Chart, assistance should be sought from
the nearest local representative or via our technical support e-mail (detailed in the footer).
Important design features of this range of ICS Heavy Duty Mill Master Slurry Pumps include:
• Cartridge type upgraded ICS Bearing Assembly for extended life compared to competitors’ pumps.
• Replaceable casing liners (hard metal, rubber or urethane can be site retrofitted).
• Heavy duty screw thread Impeller attachment.
• Through-bolt design throughout for easier maintenance.
• Self-setting and self-aligning Patented Slurry Seals.
• Minimum number of casing bolts
2. IDENTIFICATION OF PARTS
Each part has a basic part identification. Parts with the same name have the same basic part abbreviation,
regardless of pump size. For example, all stuffing boxes are designed as SBOX forwarded by a specific letter to
the size. A stuffing box to suit a 4x3 D frame pump would be MMDSBOX.
Refer to the Sectional Arrangement Drawing for the appropriate size of ICS Pump for complete identification and
description of component parts.
In all communication with ICS, or its distributors, and particularly when ordering spare parts, the correct
component names and Part Numbers should be used at all times to avoid supply of incorrect parts.
3. BEARING ASSEMBLY – ASSEMBLY AND MAINTENANCE
The Bearing Assembly is assembled and maintained as described in separately available ICS manuals.

4. PUMP ASSEMBLY INSTRUCTIONS
Reference to a Sectional Arrangement Drawing provided by ICS for the particular pump being assembled will be
of assistance in the instructions outlined in the following sections.
All parts dismantled during pump overhaul should be inspected to determine suitability for reuse,
and identification of new parts should be checked.
Parts suitable for re-use should be cleaned and if necessary re-painted. Matching faces should be free of rust,
dirt, and burrs, and have a coating of anti-seize compound applied prior to assembly, so that the pump remains
easy to fix in future overhauls.
Small standard fasteners should preferably be replaced, and all threads coated with suitable compound (such as
anti-seize) before assembly.
Replacement of all elastomer seals (such as O rings and joint rings) is recommended at major overhauls, as
these materials usually deteriorate with use. Direct exposure to sunlight causes accelerated deterioration of
elastomers and will result in more frequent changing of parts.

(i) Insert Adjusting Bolt in Base from drive end. Fix Adjusting Bolt into Base by screwing on one nut and
fully tighten. Fit the additional two nuts supplied with the Adjusting Bolt and separate with two flat
washers. These nuts should remain loose on Adjusting Screw and spaced well apart so that the Bearing
Assembly will slot into place.
(ii) Apply anti-seize compound to semi-circular machined surfaces on the bottom of the Bearing Housing
and onto the mating support cradle in the Base. This helps reduce corrosion in this area (which is
important for maintaining low maintenance costs for packing and expellers).
(iii) Approximately match the Bearing Housing ears with the hold down bolt holes in the base then lower the
Bearing Assembly into the Base and ensure the lug has fitted over the Adjusting Screw and between the
nuts and washers.
(iv) Fit Clamp Bolts through Base from below. Mount a Clamp Washer on each bolt (domed side up) then
screw on the nuts. Fully tighten Bolts on the left hand side of Base as viewed from the impeller end. At
this stage the Clamp Bolts on the other side should remain finger tight only, to maintain alignment but
allow axial movement of the Bearing Assembly.
(v) Apply anti-seize compound to Shaft. This will assist fitting and removal of shaft components, and prevent
damage to Shaft surfaces by moisture.
(vi) If not repaired in-situ, fit an appropriate assembly cradle (such as two blocks of timber with coach
screws), to underside of Base to prevent the pump from tipping forward during assembly of the wet end,
as shown in Fig 1. Ensure that the Base is high enough above the floor for the frame plate and components
to be assembled.

4.1.2 FITTING FRAME PLATE AND COVER PLATE BOLTS – Ref Fig 2
Figure 2 - Assembling Frame Plate and Cover Plate Bolts
(i) Apply anti-seize compound to the recesses in the base where the Frame Plate spigot engages. Fit Frame
Plate to Base, ensuring that the Frame Plate locating spigot engages with the corresponding Base arms.
For pumps 6x4 and larger, Frame Plates are provided with either radially tapped holes for eyebolts or
lifting lugs to assist fitting.
(ii) Insert Frame Plate Studs or Frame Plate Bolts, depending on pump size. Fit and fully tighten nuts.
Depending on the pump size, the Frame Plate is bolted externally using studs. whilst others use bolts
which are inserted from within the Frame Plate. In most pump sizes, the Frame Plate can be rotated to
provide eight alternative angular discharge positions.
(iii) Ensure the cover plate bolts are clean, and remove any burrs. Cover threads with anti-seize. Fit Cover
Plate Bolts Through Frame Plate lugs.
