  • Entire rotating element can be removed without disturbing pipe connections or driver
  • Extra deep stuffing box with split glands
  • Balanced axial & radial thrust bearings
  • Seal cages
  • Clockwise or counter clockwise rotation

    Casing - Horizontally split, upper and lower half bolted and doweled to provide perfect alignment. Bearing supports are cast and bored integrally with lower half casing. Upper half easily removed for inspection and maintenance without disturbing piping. Casing wear rings are standard and are field replaceable.

    Impeller - Enclosed, double suction type, accurately machined and balanced for smooth operation. Impeller wear rings are standard on 8 discharge and larger sizes, optional on other sizes.

    High Strength Shaft - High strength steel shaft with renewable shaft sleeves provides protection from corrosion and abrasion.

    Compact Size - Overall equipment size and weight have been decreased, permitting larger capacity pumps to be installed in smaller areas.

    Materials of Construction - Bronze fitted and all iron are standard. Ductile iron, all bronze and stainless steel, are also available on most sizes.

    Stuffing Box - Extra deep stuffing box accepts minimum of five rings of packing or a seal cage. Wide range of mechanical seal options available to suit many applications.

    Advanced Design - Short, heavy shaft and close bearing centers limit shaft deflection and assure longer pump life with minimal maintenance.

    Long Life Ball Bearings - Cartridge mounted, double-row thrust bearing may be inspected or serviced without disturbing casing bolts or piping. Grease or oil lubrication is available.

    Maximum Interchangeability - Standardized parts simplify the design. Shafts, bearings, sleeves, seals and packing are identical within a power group.
