Pump drives are one of the most common places to use an NM flexible coupling. The size should be selected from the actual motor and pump shafts and the operating duty, not from motor frame size alone.<\/p>\n

For replacement pumps, measure both shafts even when the old coupling looks reusable.<\/p>\n Replacement and installation notes<\/h2>\nFor replacement work, include the existing coupling marking, photos and measurable hub dimensions. For new installations, provide the shaft drawing or actual shaft dimensions. Align the connected equipment to the machine manufacturer\u2019s requirements before operation.<\/p>\n \n Y\u00eau c\u1ea7u b\u00e1o gi\u00e1 kh\u1edbp n\u1ed1i NM<\/h2>\nN\u1ebfu bi\u1ebft k\u00edch th\u01b0\u1edbc NM, h\u00e3y cung c\u1ea5p \u0111\u01b0\u1eddng k\u00ednh tr\u1ee5c, t\u1ed1c \u0111\u1ed9 v\u1eadn h\u00e0nh, thi\u1ebft b\u1ecb d\u1eabn \u0111\u1ed9ng v\u00e0 s\u1ed1 l\u01b0\u1ee3ng.
