S&L Non-Clog Pumps from Smith & Loveless have an oversized, stainless steel pump shaft that minimizes overhang, resulting in significantly less shaft deflection and greater 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 inches. Close tolerances are in all cases tighter than NEMA specifications. The pump impeller is designed for maximum efficiency. Trimming the impellers inside the shrouds leaves the back shroud full diameter to prevent stringy material from winding around the shaft and reducing efficiencies. 913/888-5201; www.smithandloveless.com.
