KS250 Supreme Centrifugal Sand Pump

The KS250 Supreme has a semi-open impeller design that contains wide-tipped vanes and a more tangential circumference of the suction allowing the pump to create a smoother flow pattern when handling abrasive fluids. The KS250 Supreme is available in hard iron, supreme hard iron, and aluminum bronze fluid ends. The pumps can be unitized with electric motors, diesel engines, and hydraulic motors (horizontal, vertical, or close-coupled configuration).

Design Features:

• Versatile stuffing box

• Thick, strong, concentric casing with replaceable casing wear pad

• Casing gasket receded for protection.

• Replaceable stuffing box cover with dual stuffing box bolts

• Long-life, no-adjustment mechanical seal available for near zero leakage

• Replaceable shaft sleeve

• Solid Frame base

• Labyrinth seals for maximum bearing protection

• Duplex angular contact bearings

• Full pipe diameter entrance for minimum turbulence and maximum efficiency

• Wide semi-open impeller creates lower axial thrust for improved bearing life

• All sizes feature the same power end

Typical Configurations:

3x2x13       6x5x14
4x3x13       8x6x11

Note：

1. XX－Impeller code－Firsr X equals diameter of impeller in inches minus 4.Therefore 10″=6,9″=5 etc…14″ use lettet A;

2. Second X equals frational data in1/8′s.Therefore 1/8″=1, 1/4″=2 ,etc…Thus a 10.5″impeller is coded as 64, 12″impeller is coded as 80, 13.25″impeller is coded as 92 etc…

3. YYY－the metric diameter of impeller，therefore 12″ is coede as 305mm，11″ is coded as 280mm
