Container Pump 6L/18L

Air-free dispensing of low-viscosity fluids—with uninterrupted refilling and reduced air bubble formation.

Container Pump – Air-Free Material Supply Without Production Interruption.

The D+P container pump enables a consistent and reliable supply of low-viscosity media to dosing applications. It was specifically developed for liquids with poor air separation properties, where trapped or dispersed air can impair dosing quality.

A key feature of this solution is the container's pressureless operation. While trapped air bubbles can be compressed in a pressurized tank, in the pressureless system they can rise to the surface in a controlled manner and escape from the medium. This reduces the formation and retention of micro-air bubbles in the material – a crucial requirement for a stable and reproducible dosing process.

The container filling process has also been designed for the gentlest possible material handling. An integrated, angled guide plate directs the medium along the container wall into the tank in a controlled manner. This reduces turbulence and the introduction of additional air during filling. The hopper pump also allows for refilling during operation, eliminating the need to interrupt production for filling. Filling can be conveniently carried out via a quick-release coupling, for example, using a filling trolley, or alternatively via a filling nozzle.

For hygroscopic media, the system can be optionally equipped with a ventilation filter including a desiccant insert. This protects the medium from absorbing moisture from the ambient air, thus reducing the risk of undesirable changes to the medium. The hopper pump is available in 6-liter and 18-liter versions, offering a flexible solution for varying material quantities and dosing requirements.
