2. Support feet are precision machined and fitted to the pump bracket to assure better coupling alignment during variations in pumping temperature.
3. Standard heavy duty shafts produce minimum deflections, and oversized bearings provide up to 6 times AFBMA-B10 minimum bearing life even under extreme conditions.
4. Precision-machined carbon steel shaft* allows for maximum loading with less than .002 inch deflection at sealing surfaces.
5. Elastomer gaskets seal both the shaft sleeve and impeller capscrew to prevent shaft corrosion and isolate shaft from pumped liquid.
6. Long-life mechanical seal is supplied with EPT elastomers, 303 stainless steel metal parts, carbon rotating washer, and Ni-Resist stationary seat. It is pre-assembled on a bronze shaft sleeve (cartridge seal assembly) to ensure correct mechanical seal positioning and easy servicing.
7. The slip-fitted, pinlocked bronzed shaft sleeve, extending through the seal box, prevents shaft wear and corrosion.
8. With vastly improved flow hydraulics, the unique 8-bladed impeller stabilizes flow and reduces turbulence. It is manufactured by a vacuum-cast foundry process that provides smooth waterways and dimensional control not found in sand castings.
9. Impeller-volute matching minimizes volute losses. Computerized design/testing carefully matches the advanced impeller to a carefully designed volute. The matching of internal pressures and velocities improves hydraulic efficiency and allows the impeller to produce its certified design flow and head minimizing wasted horsepower.
10. Extra large oil sump*, allows for generous oil supply with outstanding heat dissipation.
11. Conveniently located grease reservoirs* provide positive flush-through lubrication. When fully lubricated, it provides sufficient grease for up to 20 months service.
12. Lipseal and slinger*, located outboard at each bearing, prevent dirt, water, etc. from contaminating the lubricant, even when washed down with a hose.
13. Improved bracket design incorporates a diverging seal chamber that creates a vortex action to stimulate seal chamber circulation. This eliminates air and foreign particle build-up and carries off frictional heat from seal faces. An internal flush line increases recirculation in seal chamber, provides manual venting, and, if required, can be adapted to an external flush line. This design eliminates the need for strainers, filters, or cyclone separators, since the pumping action does the job.
14. Adequate drain tappings.
15. Suction and discharge gauge tappings.
16. Back pull-out design allows for maintenance work without disturbing piping.
