The 201 series is the standard 2.0 ml inner-spring lotion pump for body-care packaging. A machined piston chamber holds the dose steady from the first stroke to the last, and the ribbed inner collar grips the bottle neck without over-torquing during capping. Moulded in PP with a smooth collar, it takes colour matching, silk-screen, hot-stamp and metallised finishes. Suction tube length is cut to your bottle height, and the pump ships assembled with an overcap so filling lines can run without extra handling. This variant carries a matte collar, chosen for a softer, low-glare finish on premium skincare bottles.
