DODGE PARA-FLEX, D-FLEX, and GRID-LIGN couplings offer a superior solution for a wide variety of pumps, including centrifugal and positive displacement applications, among others. CENTRIFUGAL PUMPS Input RPM - Typically reduced from motor speeds Օ Flow - Steady Starting Conditions - Low pressure, low loads Օ Sizing - The low starting loads require a 1.0 - 1.25 service factor when sizing couplings Dթfinition - Constant pressure, steady flow Typical Materials - Water or constant viscosity liquids Օ Driver Equipment - Typically electric motors Design - Spacer couplings are used primarily in centrifugal pump applications. These couplings are designed for motor-pump installations where easy access to pump bearings, seals, and impellers is required without moving the connected units Pump Reducer Motor Coupling Motor ՗ Coupling -E3- Belt Drive Pump Reducer BALDOR
