Purchase Fewer Wear Parts

The LCC-M Series features only three main wear parts: the shell with built-in hub-side liner; the impeller; and the
suction-side plate liner.

Reduce and Simplify Maintenance

The features built into GIW pumps reduce maintenance costs. For example, the cast ring on the hub side of the
shell fits into a rabbet groove on the pedestal. It supports the weight of the shell and provides automatic alignment.
It also allows the shell to be installed in any discharge position of 45 degree increments.

The radial bearings are a self-aligning, double-row, spherical roller-type design and are adapter mounted. They
minimize shaft deflection and axial movement. This arrangement accepts mechanical seals without any change in
the bearings. The slip on shaft sleeve has a heavy-fused, carbide coating, which results in extended sleeve and
packing life.

A machined saddle on the pedestal and a machined fit on the split-cartridge bearing housing provides automatic
alignment. An adjusting screw located at the end of the pedestal simplifies impeller clearance adjustment for
maximum wear life and pump performance.

Maximize Wear Life

All GIW shells are designed for maximum wear life using GIW's predictive wear computer program. The impeller is
designed for wear-resistant operation in highly abrasive slurries using GIW's flow simulation computer program. Its
twisted-vane design provides you with highly efficient passage of large solids, superior suction performance and
excellent wear resistance. The suction-side plate of the LCC-M can be rotated at intervals to increase wear life.

Bearings
Bearings offer a minimum L10 life of 30,000 hours at maximum conditions, unless otherwise specified.

A double-row, taper roller bearing carries the drive load and hydraulic axial thrust without need of thrust
compensating clearing vanes on the impeller.

The impeller-end radial load is carried by a double-row, spherical roller bearing. Bearings are pressed to the shaft,
which then slides into the housing from the drive end.

Inpro/Seal
Inpro/Seal bearing isolators are incorporated into the standard LCC bearing assembly seal design. A bearing
isolator is a mechanical device that isolates a bearing from its environment.

This product enhancement eliminates the possibility that the bearing assembly will be contaminated by water or
solids, ensures that the bearing assembly will be properly lubricated and does away with the maintenance and
replacement costs associated with lip-design oil seals.

GIW offers two Inpro/Seal designs:

The drive or thrust end uses the standard VBX, or vapor block, bearing isolator design.
The pump or radial end uses the ford-wing bearing isolator design, which incorporates an integral flinger.

The Inpro/Seal bearing isolator is manufactured in two parts: a rotor and a stator. The rotor revolves with the shaft,
driven by a tightfitting drive ring fixed to the shaft. It also has a stationary component fixed to the bearing housing
with a press fit and an O-ring gasket.

The two pieces are assembled into a single unit and axially locked together by an O-ring insert. No frictional contact
 9/1/2020 | Page 6 of 8

occurs between the rotor and stator while the isolator is running.

The seal's key design feature is a specially seated O-ring, the Vapor Blocking Ring, that lifts clear when the shaft is
in operation, but positively seals when the shaft is at rest.

The new end covers are completely interchangeable with the previous design. To change a bearing assembly to the
new Inpro/Seal design, simply order the new end covers and the Inpro/Seal.

Since there is no mechanical contact-friction, heat or wear, the Inpro Seal bearing isolator lasts a long time. The
manufacturer reports that seven to 15 years of constant service is not long in the life of an Inpro/Seal bearing
isolator.

Lubrication
Standard bearing lubrication is grease. Oil bath lubrication is also available.

Motor Mount Arrangements

GIW pumps with overhead motor mount arrangements do not require a separate base plate. The pump pedestal
can be bolted directly to a concrete foundation with the motor mounted on the pump's motor-mounting structure.
GIW pumps with side motors do not require a subbase: the pump and motor with slide rails can be mounted to
concrete foundation. Some field installation and alignment of the motor and drive are required after installation of
the pump.

Testing
Our performance curves are based on actual, full-size running tests on clear water. We guarantee our pump
performance according to the Hydraulic Institute standards, section 1.6.5.3, acceptance level B and GIW ISO 9001
procedure ER .012.

Hydrostatic tests can be carried out on all pumps at no additional charge in accordance with GIW ISO
9001procedure 10.0001.01.00. These are performed at 1-1/2 times the operating pressure or 125 psi, whichever is
greater.

Materials Overview
LCC Series Slurry Pumps are available in three material configurations: all hard metal; split-case, rubber-lined with
metal or elastomer-lined impeller; and extra-heavy, all metal. The all-metal design may develop slightly more head
at a given speed and is capable of operating at much higher speeds than the elastomer design.

The wet ends of the LCC slurry pump are interchangeable. The hard metal shell, impeller and suction piece can be
interchanged with the ductile iron outer casings, rubber liners and elastomer or metal impeller. The pump shaft,
suction and discharge piping are not affected. This feature provides excellent adaptability to meet changing
pumping conditions.

LCC Series Slurry Pumps feature pedestals and bearing housings of gray cast iron. The metal casings of LCC
rubber-lined pumps are cast of ductile iron for increased pressure rating.

Gasite WD28G, Standard

The impeller of the LCC-R and the wear parts of the LCC-M are manufactured of a high-chromium white iron called
Gasite WD28G white-iron alloy. Gasite white-iron castings are stress relieved and heat treated for optimum
properties.

Gasite WD28G is a proprietary metal. It exceeds the requirements of ASTM specification A532-93a. This high-
chromium material offers excellent wear life along with resistance to chemical corrosion when applied in slurries
with pH as low as three.
 9/1/2020 | Page 7 of 8

Other specialty white irons are available.

Polyurethane, Standard For Elastomer-Lined Impeller

Polyurethane is a two-part elastomer resin that has higher hardness and strength than most rubbers. It is the
standard material for LCC elastomer-lined impellers. Polyurethane exhibits excellent resistance to fine particle
abrasion and exhibits good chemical resistance.

Polyurethane is formulated to provide high-quality parts cast in molds for maximum dimensional integrity.
Polyurethane's success as an abrasion-resistant material for pump parts has been mainly in applications where
particles are smaller than 0.04 inch (one millimeter) or 16 mesh. Polyurethane is susceptible to hydrolytic
degradation in temperatures of 160 ºF (70 ºC) and above.

Elastomers
Elastomers are available in the form of replaceable liners and urethane impellers in all sizes. Natural or pure gum
rubber is generally preferred when wear life is of prime concern, operating temperatures are below 150 ºF (65 ºC)
and petroleum products are not present. GIW Industries stocks liners in pure gum rubber.

LCC Rubber-Lined slurry pumps are available with Gasite WD28G or urethane-lined impellers.

Rubber: Pure Gum Rubber, Standard

Pure gum rubber is the standard molded rubber liner material for LCC pumps. It gives the highest resistance to
abrasion of all the elastomers because of its exceptional resilience.

Rubber: Natural Rubber, Optional

Natural rubber is resilient when impacted by suspended particles in slurry mixtures. High-quality natural rubber has
excellent abrasion resistance, but oil and petroleum products cause swelling.

Its abrasion resistance exceeds that of any other elastomer as long as particles are not large enough to cut the
rubber. As a result, natural rubber is the most commonly used material in abrasive pumping services where
maximum particle size is below 14 inch (10 millimeters) and where organic compounds that attack rubber are not
present.

Rubber: Natural Rubber Compounds, Optional

Carbon compounded with pure gum rubber significantly increases rubber's tensile strength, tear resistance and
resistance to certain chemicals and temperatures. The resilience and wear resistance are not adversely affected.

A variety of natural rubber compounds are available. Each compound variation to the pure gum is formulated to
emphasize a desirable aspect of chemical or temperature resistance while maintaining the maximum abrasion
resistance possible. The high resiliency of pure gum natural rubber is modified as reinforcing chemicals, such as
carbon, are introduced into the compounds.

Neoprene, Optional
Neoprene is a synthetic rubber. It has less abrasion and chemical resistance than pure gum rubber, but greater
strength and resistance to temperature, mechanical damage and petroleum products.

Neoprene compounds are generally used where the presence of oils, chemicals or temperatures above 150 ºF (65
ºC) limit the use of natural rubber.

Other synthetics, such as Butyl, Nitrile and Hypalon, are available. These special compounds may be needed to
meet specific chemical and temperature conditions.

Shaft Seal Design

The shaft seal design of LCC Series Slurry Pumps is governed by the presence of solids and the availability of seal
 9/1/2020 | Page 8 of 8

water. Three basic configurations exist: the stuffing box, expeller and mechanical seal.

Stuffing Box
GIW uses two designs for stuffing box assemblies. Our standard design is a full-flush design for severe applications
where maximum flush of the shaft sleeve is required. The minimum dilution design is a restricted flow design
recommended for applications where available seal water is limited or where dilution of the slurry presents
problems.

The LCC slurry pump stuffing box must, in most cases, be supplied with an external water flush to prevent the
solids from entering the sealing area where they would cause accelerated wear. For both designs, seal water
should be furnished at 10 psi above the discharge pressure.

The standard LCC stuffing box features one ring of packing forward of the seal water ring to limit seal water usage.
The design of the packing box minimizes the use of flush water. Braided Teflon®-impregnated flax packing rides on
a carbide-coated shaft sleeve.

Expeller Option
Expellers (centrifugal seals) are available on LCC Series Slurry Pumps. The expeller seal option provides a
centrifugal seal by placing an additional impeller (expeller) behind the main impeller to overcome the developed
pump pressure at the stuffing box.

In the case of precipitating solids, a liquid flush may be required and can be accomplished by replacing the forward
ring of packing with a spacer. This allows easy addition of purge fluid through the stuffing box seal water inlet
connection.

GIW's standard expeller option requires a longer shaft to allow installation of the expeller between the pedestal hub
and pump shell. The expeller wear parts are constructed of abrasion-resistant white iron.

The maximum positive suction pressure available to the pump places limitations on the expeller. This is generally
limited to approximately 10 percent of the operating discharge pressure. For this reason, expellers may not be
suitable for closely spaced, multistage applications. Expellers also require approximately five to 10 percent more
power to operate.

Mechanical Seal Option

Although mechanical seals require special selection, operation and maintenance, they are becoming more common
in slurry applications where zero dilution of the product is required, where no service water is available and where
product leakages are not tolerated for safety or environmental reasons.

The LCC Series Slurry Pump mechanical end is designed to minimize shaft deflection and axial movement for
optimal mechanical seal performance.

Many different mechanical seal designs exist: from severe-duty, custom-designed types to standard, commonly
available types. The correct seal type for any given application depends on the nature of the slurry.

Mechanical seals offer pump operation without the need for seal water. This removes the potential for product
dilution or leakage. Many mechanical seals operate without an additional cooling medium. These are most
preferred in slurry applications.
