The Mega Slurry Pump features a single stage, compact arrangement that allows easy maintenance of wet end components. The rear pull out design permits removal of the mechanical end without disturbing the wet end or piping. It is recommended for pumping coarse to fine particles from solids laden wastewater to aggressive slurries of an abrasive and/or corrosive nature.
Hard Metal
Hard metal Mega Slurry Pumps feature a single wall shell and a hub plate of high chrome white iron. These pumps are suitable for high discharge head, mildly corrosive slurries and a wide range of particle sizes. Custom materials are available for highly corrosive slurries.
Impeller
The Mega three-vane impellers are cast from high chromium white iron.
Wet End Materials
The wet end components are designed for long service with minimal maintenance. The shell, impeller and hub plate are cast in one of the proprietary GIW alloys, depending on the required service.
Gasite® WD28G
The standard material for metal wear parts is Gasite WD28G, proprietary high chromium white iron. This material offers excellent wear life along with resistance to chemical corrosion when applied in slurries with pH as low as five.
Shaft Seal Design
Shaft seal design is governed by the content of solids and the availability of seal water. Two basic configurations include the stuffing box and mechanical seal.
Stuffing Box
Supplied for standard application, the stuffing box requires an external water flush to prevent the solids from entering the sealing area where they would cause accelerated wear.
Mechanical Seals
The Mega mechanical end is designed to minimize shaft deflection and axial movement for optimal mechanical seal performance. Many different mechanical seal design exists from severe duty, custom types to standard, commonly available seals. The correct type for any given application depends on the nature of the slurry and the system operating conditions.
Mega Mechanical End
The Mega pump uses a cartridge bearing assembly with integral mounting flanges. This provides accurate alignment with easy maintenance. The bearing housing is a precision-machined cast iron cylinder with bolt on end covers. Bearings are mounted on the shaft allowing a single assembly to be installed in the cartridge.
Bearings
The precision ball bearings used in Mega pumps offer a maximum service life with minimum maintenance. Double ball bearings carry 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 single row ball bearing.
Inpro/Seal®
Inpro/Seal bearing isolators are incorporated into the standard mega bearing assembly. This product enhancement protects the bearing assembly from contamination by water or solids and eliminates the maintenance and replacement costs associated with lip design oil seals.
The Inpro style end covers are completely interchangeable with the previous lip seal design. To update a bearing assembly, simply order the new end covers with the Inpro/Seal.
Inspection and Maintenance
Pump inspection and replacement of the impeller can be performed without removing the suction or discharge piping to minimize pump maintenance time.
The entire bearing assembly can be quickly removed from the pump. The rear pull out design permits rapid change to minimize downtime during routine maintenance.The GIW Mega Slurry is a high-performance, low maintenance slurry pump recommended for coarse or fine particles from solids-laden waste water to aggressive slurries of an abrasive and/or corrosive nature.
