REDUCED INLET MULTIPLE PUMPS Basedonyourapplicationrequirements theW600multiple pumpmay be supplied with a single inlet on two sectionpumpapplicationsanddual inletsonthreesectionpumpapplications. Reducedinletsprovideoverall systemsavingsby reducing thecost of redundant inlet hose and fittings. Contact Concentric regarding your reduced inlet multiple pump application. TheW600 offersmultiple pump configurations up to 3 sections. Multiple pumps provide multiple hydraulic functions from one power source at a significantly lower cost than separate pumps. Thedrawingsandchartsprovidedimensional information as well as shaft and coupling load information for the W600 two and three section pumps. If the shaft loading, coupling, andsectionsequencerequirements outlined on this page are all met, the W600 multiple pump will exhibit the same performance as theW600 singlesectionpumpsoutlinedonpage2of thiscatalog.

CW ROTATION INLET OUTLET COUPLING LOADING TWO SECTION: (P2 x V2) < 2427 (METRIC) 2150 (ENGLISH) THREE SECTION: (P2 x V2) + (P3 xV3) < 2427 (METRIC) 2150 (ENGLISH) In multiple pumps, shaft end section must have largest displacement. Each consecutive section must have displacement equal to or smaller than section preceding.
