In this paper, we give a necessary and sufficient condition for cyclic act to have a (PF′′)-cover and give some classes of monoids that all cyclic right S-acts have a Condition (PF′′)-cover. ##We show that every weakly pullback flat cover is also (PF′′)-cover and every (PF′′)-cover is (P′)- cover, but the converses are not true.
