'''Precision Dosing Devices''' designed to add water-soluble fertilizers or wetting agents to professional and retail growing media. They comprise two parts: a pumping unit with tanks, pump and structure, and a distribution unit with valves, nozzles and diverting plates installed over a conveyor. | |||
Nowadays, modern electronics and high-precision mechanics allow the miniaturization of many items for everyday use and industrial applications. Micro annular gear pumps for fluid delivery are an excellent example. Their simple, no-valve design allows them to come in a compact size with a virtually non-pulsating, easily adjustable flow. Electronically commutated DC micro drives are particularly suitable for driving this kind of fluid machinery. Compact in size, they offer high power density and a large speed range with excellent dynamics, enabling high-precision control of flow rates from the smallest volumes to a constant maximum throughput. The smaller a device can be built, the easier it is to transport, install or integrate into existing systems. In addition, precision production processes for metal, ceramic or plastic components allow for closer fits and narrower gaps. This then has a very beneficial spinoff on the efficiency of small and miniaturized fluid machinery such as displacement pumps. | |||
