A turnaround in pump dispenser quality

Accurate data essential to prevent incorrect settings being applied on the production line

A typical test involves a container sample held securely by four gripping pegs, enabling manual application of torque

Torque tests performed on pump dispensers are helping one German manufacturer check seal quality to optimise its production.

Pfeiffer wanted to quantify the correct level of torque required to seal pump dispensers, commonly used within its dosing systems and atomisers in the pharmaceutical and cosmetics industries.

A former customer of Mecmesin and therefore familiar with its products, Pfeiffer contacted the company again for this new application. It was critical to gain accurate data to prevent incorrect settings being applied on the production line, as this would result in poor performance of the pump dispenser and possible leakage of the container contents.

Mecmesin’s Tornado digital torque tester is used to check the application and release torque of closures. A typical test involves a container sample held securely by four gripping pegs, enabling manual application of torque between 0.8 and 0.85N.m. Upon completion of the test, seal tightness is verified and the correct torque application determined.

The Tornado is a simple and effective digital torque tester, providing consistent high accuracy results. A MK2 model supersedes the MK1 tester Pfeiffer uses, offering even greater versatility.

Available in four capacities – 1.5, 3, 6 and 10N.m – this manual torque tester records up to 500 readings, tests tamper-evident closures and enables results to be exported to peripheral devices such as PCs and printers for further analysis.
