Machine configuration
Ask a water filling machine supplier to explain the proposed filling principle before comparing valve counts. The right proposal connects your water condition, bottle and output requirement to a defined fill measurement and trial. Valve quantity or a stainless-steel description alone is not enough to select the machine.
Identify still water, expected product temperature and any product conditions requiring review. Submit the bottle opening and geometry, target fill and output by format. Carbonated or other beverages require a separate process assessment; do not extend a still-water quotation by assumption.
The bidder should identify whether the proposed machine controls a level, volume, mass or another defined endpoint, and show how that endpoint is adjusted and checked. Different filling technologies exist; a catalog example from another manufacturer is not evidence of the proposed configuration.
Request a wetted-parts drawing, seal identification, access requirements and the supplier's cleaning and maintenance instructions. Ask which tasks require stopping and isolating the machine, what spare parts are recommended and whether the proposal includes them.
Agree the bottles, stable supply condition, measurement method, sampling points and acceptance limits before FAT. Retain results across representative filling positions and formats, including the setup state, rather than accepting only a short video of bottles moving.
No single valve count establishes output. The supplier must demonstrate the specified bottle and product under the agreed operating and acceptance conditions.
No. Ask for a separate process and container review, including the proposed pressure-related filling method where relevant.
First define the product acceptance requirement, then ask how the offered technology measures it. A visual level check and a net-content measurement answer different questions.
