The 401 series is the high-output workhorse: 4.0 ml per stroke, sized for shampoo, conditioner, shower gel and thick body lotion. The larger piston chamber moves viscous product without sputtering, and the reinforced collar holds torque on wide-mouth 33 mm bottles. Available with a smooth or matte collar, in standard or custom colour, with silk-screen, hot-stamp and metallised decoration. Dip tubes are cut to your bottle depth, and the pump is supplied assembled with an overcap for automated filling lines.
