Shaft end section MULTIPLE PUMPS REDUCED INLET MULTIPLE PUMPS Reduced inlets provide overall system savings by reducing the cost of redundant inlet hose and fittings. Contact Concentric regarding your reduced inlet multiple pump application. Concentric multiple pumps are also available with reduced number of inlets. Please contact Concentric for details. Please contact Concentric for pump applications requiring independently sealed sections. MULTIPLE SECTION SHAFT LOADING Max. drive shaft load index “A”, see table below. for double pump A = (p1 x V1) + (p2 x V2) for triple pump A = (p1 x V1) + (p2 x V2) + (p3 x V3) for quadruple pump A = (p1 x V1) + (p2 x V2) + (p3 x V3) + (p4 xV4) Note: P = actual pressure in bar, V = applicable displacement from Table pages 6-9. The two following parameters are of the utmost importance when selectingmultiple pumps andmust never be exceeded: - Drive shaft load index “A” in chart at right. - Internal coupling load index “K” in Coupling Loading below at right. In multiple pumps, shaft end section must have largest displacement. Each consecutive sectionmust have displacement equal to or smaller than section preceding.
