ABSTRACT OF THE DISCLOSURE A liquid -dispensing pump arrangement permits positive setting into various full-stroke, stroke limited, and off positions by rotation of the dispensing head thereof. The arrangement includes a reciprocating pump having a dip tube, a pump body, and a depressible stem and which is supported in a screw cap or other closure. A pedestal on the screw cap has longitudinal detents on a circumferential surface thereof, and also has a helical ramp thereon extending at least part way around the stem. A finger-depressible push-button dispensing head atop the stem has a radial outlet nozzle and a depending skirt which overlaps the circumferential surface of the pedestal. Fins or vanes on the skirt are spaced apart and engage the detents on the pedestal. The vanes are resiliently flexible and normally engage the cutout detents to establish each rotational position, but can be deflected by manually turning the dispenser head so that the latter can be easily rotated to another desired position. In a locked or off position, an upper surface of the ramp prevents any down- ward travel of the dispenser head.
