An intermediate-mass black hole (IMBH) was recently reported to reside in thecentre of the Galactic globular cluster (GC) NGC 6624, based on timingobservations of a millisecond pulsar (MSP) located near the cluster centre inprojection. We present dynamical models with multiple mass components of NGC6624 - without an IMBH - which successfully describe the surface brightnessprofile and proper motion kinematics from the Hubble Space Telescope (HST) andthe stellar mass function at different distances from the cluster centre. Themaximum line-of-sight acceleration at the position of the MSP accommodates theinferred acceleration of the MSP, as derived from its first period derivative.With discrete realizations of the models we show that the higher-order periodderivatives - which were previously used to derive the IMBH mass - are due topassing stars and stellar remnants, as previously shown analytically inliterature. We conclude that there is no need for an IMBH to explain the timingobservations of this MSP.
