Mission Halco 2500 Centrifugal Pump Packing 3 Ring Seal H2537-24A, MCM 250 series Pump Packing 3 Ring for Mechanical Seal
The Mission 2500 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 2500 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 shaft sleeve

• 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
