The less the amount of material to be mixed, the greater the challenge for the dosing system: Due to the World’s increasing miniaturisation in areas such as electronics and the associated high demand for ever smaller and more precise dosing, preeflow has developed the eco-DUO330. This system provides the answer to numerous questions from application engineers, material manufacturers, plant engineers and product developers. Be it in medical technology, optics and photonics, the manufacture of electronic components or in the field of biochemistry and the production of semi-conductors.

Adherence to the exact mixing ratios of the 2 component materials and its precise coverage can greatly influence the processes and applications from time to time. Even small deviations can negatively affect the desired results. Compounds harden only partially, adhesive bonds do not reach their load limit and, in the worst case, chemical reactions from the materials could have an unforeseeable impact on the user.

With the newly developed eco-DUO330, dosing quantities of 0.005 ml (per shot) is achievable. Irrespective of temperature, time, pressure and viscosity – dosed as a dot or bead. Therefore, the smallest quantities can be created at that very moment. The microprocessor-controlled system creates a dosing accuracy of ± 1 % and repeatability of over 99 %. And this whole process is reliable and reproducible.

The central component of the dispense module is a micro annular gear pump (mzr-pump), that is already working very precise in laboratory automation and diagnostics. mzr-pumps are characterized by low pulse flow and a service life of several years. By using these rotary positive displacement pumps, pipetting of the smallest liquid amounts during the dosing process is possible as well as rinsing with high flow rates.

The size of the module corresponds to half the syringe pumps format. It combines pump, filter and valve. With the help of a microcontroller the module can process the same programming commands as a syringe pump.

The hydraulic diaphragm metering Orlita Evolution form an integrated product range with stroke lengths of 15 to 40 mm. This covers the capacity range from 3 to 7,400 l/h at 400 to 10 bar. A wide range of drive versions is available, including some for use in Ex-zone 1 and 2. The Orlita Evolution product range is designed to comply with API 675. This pump serie meets the most exacting safety requirements as an extremely robust hydraulic diaphragm metering pump. It stands out thanks to its PTFE multi-layer diaphragm with integral diaphragm rupture warning system and unique diaphragm position control. Its modular construction offers extremely good flexibility in terms of applications.

These systems have been designed for the application of fertilizers, herbicides, fungicides, insecticides and other strong chemicals. The chemical tanks have a sloped bottom for complete drainage and ease of cleaning. All tanks larger than 55 gallons are fitted into double-wall containment and with double wall injection lines to protect the environment. A cover shields the pump, piping and electrical controls from the elements and excludes rain and debris, which allows 100% reclaim of uncontaminated chemical in the event of a spill or broken line.

At the specialist international agricultural trade fair AGROEXPO 2013 in Spain, Netzsch Pumps & Systems was awarded the “Primer concurso de innovación” innovation prize. This is now the third time in quick succession that the pump manufacturer has been honoured with an innovation prize for its products in other European countries. This time it was the economy version of the NBE 200 barrel emptying system for 200 litre barrels which was able to impress the jurors, who put it in second place among the 23 finalists.
