The STAR ONE non-clog pump from Smith & Loveless raises the bar on pump efficiency anywhere from 3 to 5 percent higher than previous pump models. It has an oversized, stainless steel shaft that minimizes overhang, reducing shaft deflection and improving pump efficiencies. This is achieved through minimal pump heights and rigid construction. Shaft end play is limited to bearing shake. Shaft runout is limited to 0.003 inch. Close tolerances are tighter than even NEMA specifications. The impeller is designed for maximum efficiency, as by trimming the impellers inside the shrouds, it leaves the back shroud full diameter to prevent stringy material from winding around the shaft and reducing efficiencies. 913/888-5201; www.smithandloveless.com.
