Pumping Additives to Prevent Nappy Rash

This application note provides an overview of the successful use of magnetically coupled gear pumps in the metering of the rash prevention additive (Resinol) for disposable diapers.

THE INDUSTRY

A global manufacturer of consumer goods and papers has developed a specialty application for disposable baby diapers. The company develops innovative products to meet the needs of consumers based on its assessment of consumer needs and behaviors.

THE APPLICATION

A pump is used to meter the medical product, Resinol, into the paper fibers used in making disposable baby diapers to prevent diaper rash. Diaper rash is a common problem for babies who wear both cloth and disposable diapers. This innovation falls in line with the company’s focus to develop materials and functions that ensure a broader selection of cost effective, value added products.

THE PUMP SOLUTION

Micropump GC series external gear pumps are direct coupled to a three phase inverter controlled AC motor.
