2.0cc Precision Dosage Lotion Dispenser Pump 28/410 High Speed Filling Line

At two hundred bottles a minute, a pump either repeats or it does not. This 2.0cc Precision Dosage Lotion Dispenser Pump is built for that regime: the chamber is tooled on a four cavity hot runner mould with cavity to cavity variation held under 0.04cc, and every batch is sampled against a gravimetric balance rather than a visual check. The published tolerance is 2.0cc plus or minus 0.1cc, not the looser 0.3cc band typical of general purpose pumps.

Precision matters commercially as well as technically. When the label promises 200 uses and the pump delivers 230, the brand quietly ships extra product on every unit; when it delivers 170, customers complain about running out. Holding the tolerance closes that gap and makes cost of goods predictable at the scale of a container load.

• Cavity to cavity dosage differences that show up as uneven fill weight between boxes from the same pallet.
• Pumps that bind or stall in the unscrambler above 180 bottles per minute, forcing line speed down.
• Label claims that no longer match measured output, creating a compliance question in export markets.
• Lot to lot variation that makes a brand qualify the same pump twice a year.

• Four Cavity Matched Tool: All cavities are cut in one pass and validated together, keeping cavity variation below 0.04cc so box to box weight is uniform.
• 2.0cc at 0.1cc Band: Gravimetric release testing runs twenty five units per lot, and the batch report travels with the carton.
• Unscrambler Stable Geometry: Collar shoulder and body centre of gravity are corrected for rail feeding, so heads track upright above 200 pieces per minute.
• Consistent Thread Start: Thread start position is held within 15 degrees across cavities, which removes the spin and re grip cycle on capping heads.
• Low Vacuum Decapping Safe: The head releases at 8 N, cutting label damage when a capping head misfeeds and pushes the pump sideways.
• Documented Release: Each lot ships with dosage, torque, appearance and leak data so incoming inspection can be a document review.

Specified for high output rotary and linear filling lines producing shampoo, body wash, hand wash and household cleaning products at container load volumes. The 28/410 neck suits 400ml to 1 litre HDPE and PET bottles, and the corrected geometry is compatible with the common unscrambler bowl designs used in Asia and Eastern Europe. Manufacturers running a fixed recipe and a fixed line speed are the best fit, because the pump is validated for a specific stroke set rather than a broad viscosity window.

Eight hundred pumps per carton at 55 x 38 x 40 cm, stretch wrapped six cartons per bundle for forklift handling. Minimum order quantity is 20,000 pieces, reflecting the matched tool commitment. Stock colour ships in 10 working days and custom colour in 20. Every shipment carries a batch dosage report produced on a calibrated balance, and a retain sample of twenty five pumps from each lot is held for twelve months so any field question can be answered with measured data rather than an opinion.
