The STAR ONE non-clog pump from Smith & Loveless 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 endplay is limited to bearing shake. Shaft runout is limited to 0.003 inch. Close tolerances are tighter than even NEMA specifications. By trimming the impellers inside the shrouds, the pump leaves the back shroud full diameter to prevent stringy material from winding around the shaft and reducing efficiencies. 913/888-5201; www.smithandloveless.com.
