Screw torque of pump dispensers
Pfeiffer, based in Germany, are a leading manufacturer of atomizers and dosing systems for the pharmaceutical and cosmetics industries. The company required a torque test unit to measure the application and release torque of their pump products. In particular, they wanted to define the correct level of screw torque required to seal the pump dispenser to the container.
Mecmesin provided a Tornado manual torque test instrument capable of measuring clockwise and counter-clockwise torque movement. To perform the test, the bottle container is securely positioned between the four gripping pegs. The pump dispenser is screwed onto the bottle using between 0.8 - 0.85N.m of torque.
"We perform a variety of tests on our pump products. One of which is to evaluate their release torque. In order to precisely apply torque to screw and unscrew the pumps, we use Mecmesin equipment. These instruments prove their value to us through their ease-of-use and accuracy."
