The information, samples and acceptance criteria needed to obtain a useful pump capping proposal and reduce project risk. The aim is to replace broad assumptions with a specification that can be tested against real components and production criteria.
Pack information
Provide bottle technical files where available, neck finish, pump technical files, dip-tube length, closure material, actuator lock state and representative samples from normal production supply.
Production requirement
State target sustained output, working hours, batch sizes, number of formats, planned launches and expected future capacity.
Upstream and downstream interfaces
Describe filling, conveyor height and direction, accumulation, labelling, inspection, coding and packing. Include available floor space and access constraints.
Utilities and environment
Confirm electrical supply, compressed-air quality and pressure, ambient conditions, washdown or extraction needs and relevant product hazards.
Quality criteria
Define torque or removal-torque window, pump height, directional tolerance, leak test, cosmetic standards and acceptable reject rate.
Testing and handover
Agree sample quantities, factory acceptance protocol, production materials, training, documentation, spare parts and site acceptance responsibilities.
Core principle
A pump capper should be approved against the complete production pack. Nominal diameter alone does not prove feedability, insertion, thread engagement, bottle stability or final presentation.
