4.3 Design
Details
Horizontal, end suction, modified volute casing pump with
three-vane impeller for large solids passage. Available in
interchangeable elastomer, metal and extra-heavy designs.
4.3.1 Pump
Casing
Three standard configurations are available:
1 Hard
Metal.
Single-wall casing, impeller and suction
liner of high-chrome white iron. Suitable for high-discharge
head, all particle sizes up to maximum sphere passage and
mildly corrosive slurries. Custom materials available for
highly corrosive slurries.
2 Elastomer Lined.
Radially split construction with ductile
iron outer casing and molded-elastomer inner liners.
Impeller of high chrome white iron or polyurethane. For
moderate discharge head, fine to medium particles and
highly corrosive slurries.
3
Extra Heavy Hard Metal.
Similar to hard metal version,
but with heavier sections and hydraulics suited to the most
severe slurry duties. Two-stage pressure capability.
Available in sizes LCC 150 - 500 and above.
All casings carry 125 pound, ANSI flange bolting patterns.
Adapters for conversion to DIN flanges are available.

4.3.2 Impeller
Form
All standard impellers are 3 vane, double shrouded designs
as seen in figures 4.3-1 through 4.3-3. Open-shrouded and
alternate vane number designs are available in some sizes.
4.3.3 Shaft
Seal
All standard pumps use replaceable gland packing in a
stuffing box with connections for flush water or sealing liquid.
Options include throat bushing, slurry duty mechanical seals
or expeller with grease lubricated gland packing.
