In a continuous test carried out at ViscoTec, this perfect filling behaviour could be impressively demonstrated: over the duration of a week, a commercial hand wash paste was pumped in a non-stop cycle through a ViscoTec 2RD30 hygienic pump. The pump ran at 60 revolutions per minute, which is a typical speed for this type of pump. The main components of the pump, the rotor and the stator, were measured at the beginning and end of the test. Despite the extremely abrasive particles in the paste, no wear or tear was detected in the measurements. Both at the beginning and end of the week, the results were identical.
This trial has helped to demonstrate that the endless piston principle, with its minimal-wear dosage of abrasive media and cosmetics, is clearly the right choice. With its high level internal know-how and extensive validation phase of vital components, ViscoTec more than qualifies for this type of application. From a customer perspective, a significant increase in effectiveness of the filling process for the pastes can be achieved, with a decrease in costs and maintenance down time.
