This snap-on lotion pump uses PP for the body. The snap claws use reinforced POM. This material is strong and resists fatigue. The snap dimension tolerance is ±0.05 mm. The pull-out force is over 50 N. Once installed, it will not come off. After assembly, we test 100% of the pumps for snap force and pressing function. Our QC team takes samples every two hours. They test snap dimensions and durability. The pump must hold for 5,000 presses without loosening. Workers also check appearance on every piece.
You just press this pump onto the bottle neck. No turning needed. It is three times faster than screw pumps. That helps your high-speed filling line. The snap claws have barbs. Once installed, you cannot remove it without breaking it. That is a one-time tamper-proof design. A Guangdong body wash factory had a fast filling line. They used screw pumps and often did not tighten them enough. That caused leakage. We recommended the snap-on pump. They tested 1,000 pieces. Assembly time dropped by 60%. Now they use our snap-on pump for all their products. You can change the color and output volume. Sample takes 7 to 10 days. MOQ is 10,000 pieces. We accept FOB Shanghai or Ningbo. We can send free samples for you to test. We show production videos. We do 100% inspection before shipment and give a report. If our pump damages your bottle neck, we send new ones for free and pay the freight.
