This is a custom dispensing component. Neck finish, dosage, viscosity range, spring location, dip-tube length, leak test and formula compatibility must be confirmed with the selected bottle.
Checks before sampling
Match the component to the exact bottle neck finish or approved finish drawing, not diameter alone.
Confirm formula viscosity, target output, actuator or spray pattern, dip-tube length and filling method.
Validate priming, leakage, lock or overcap function and transport handling with the final bottle system.
Application and sizing guide
External-spring pump product-path planning
This external-spring lotion pump direction is designed for projects that want to keep the dispensed product path free from direct metal contact. The complete pump is not described as metal-free until its construction is confirmed. Compare 24/410 and 28/410 options by formula viscosity, output, spring location, dip-tube length and leak performance.
