RRU Type - Drop-Out Style
    The RRU Type Uniflex coupling is designed for fast, easy installation and removal without disrupting the connected shafts. This is ideal when servicing impellers, bearings and seals. The design consists of two steel hubs fastened with cap screws to a Uniflex double flange coupling (UF Type). The RRU is easily disassembled by simply removing the cap screws and sliding out the UF center spring section.
    This design offers “quick disconnect” for drop out requirements. It can also accommodate a slightly larger shaft diameter than the standard U Type.
    Note: A complete RRU Type coupling is comprised of 2 hubs, 2 hardware kits, and a UF Type center drop out section.
