Foam pump assembly machine

This line assembles foam pumps from the body, stem, spring, ball valve, gasket and dip tube, then runs a pumping and leak check before discharge. It is built for soap and lotion dispensers, where the pump has to prime on the first stroke and hold pressure without leaking at the gasket.

Feeding, reclaiming, alignment and assembly run without an operator in the loop; each station verifies its own operation before the part moves on, which is what keeps the reject rate down when the line runs through the night.

Changeover between pump sizes is set by recipes on the HMI and swap tooling on the feeding bowls — the station order does not change.

What to send for a quote

  • 2D drawing or STEP file of the pump body, stem, spring and dip tube
  • Material of each plastic part, and the bottle neck thread you use
  • Output per stroke, prime requirement and the leak limit you accept
  • Target cycle time, annual volume and number of shifts per day

Where the money goes

Most of the cost of a pump line sits in the feeding tooling and the test station, not in the frame. A pump that arrives sideways in the bowl is a jam at station 2, and a leak test set below the pressure the bottle sees in service passes pumps that fail on the shelf after a week. Both are decided at specification, so both are quoted separately and shown in the layout drawing.
