Features

• High-efficiency double suction impeller.
• Replaceable shaft sleeves.
• Bronze replaceable wear ring.
• Mechanical seal designed for wide application range and superior longevity.
• Standard drip pan.
• Weld reinforced, groutless base (grouting recommended per Hydraulic Institute and ASHRAE).
• Top suction and discharge volute/casing to minimize footprint.
• Integrally cast mounting feet for servicing without disturbing piping.
• Flanges drilled to match ANSI Class 125 or ANSI Class 250 piping standards.
• Gauge ports at suction and discharge connections, and a drain port at the bottom of the casing.
• Impeller dynamically balanced to ANSI Grade G6.3 and fitted to the shaft with a key.
• Dry shaft design prevents circulating fluid from contacting the shaft.
• Self-flushing seal design or positive external seal flushing line.
• Optional Purocell #900 replaceable cartridge filter with shut-off isolation valve in the seal flushing line, capable of removing particles down to five microns.
• Mechanical seal features Tungsten / Tungsten mating faces with EPT elastomer rated to 250°F.
• Seal/bearing housing includes a tapped barbed hose fitting for safe routing of leaking seal fluid.
• Structural steel base with a factory-provided, integral drain pan (minimum thickness 0.1875”) and a ¾” drain connection.
• Flexible coupler (suitable for across-the-line starting and variable torque loads with variable frequency drives) with a coupler guard.

Performance and Dimensions

Performance curves are provided for 1760 RPM, 1160 RPM, and 1450 RPM (50 HZ) operation, showing head, flow, efficiency, and required NPSH for various impeller diameters and motor HP.

Detailed pump dimensions are provided in tables for various models, flange sizes, and motor frames. These tables include dimensions in inches and millimeters for components like suction and discharge flanges, overall length, width, and height.

See the official PDF for exact tabulated values and detailed performance curves.
