Gather: From laboratory to production via pilot plant

Tuesday, April 4th, 2017 von admin

A process generally undergoes initial development within a laboratory and is then made production ready in pilot or mini plants. During this scale-up, a range of different problems can emerge, e.g., in the way temperatures behave. In a laboratory, a process may be endothermic but becomes exothermic in production. How pumps behave in relation to peripheral equipment can change under full-scale production conditions, Sven Borghoff describes a coordinated pump and drive concept which makes scaling up easier.

Dosing pumps with multifunctional extensions for different pump types often used in laboratories generally have no particularly high temperature or pumping ranges. However, when scaling up, these aspects take on major significance. Gather uses its magnetic-driven pumps (Fig. 1) here. They are available in such a broad range that when scaling up from the laboratory to production via a mini or pilot plant, the pumping and control technology can be retained. The company cooperates with the chemical industry, institutes and universities to make process development from initial laboratory trials through to production easier.


Schwarzer: Customized mini-pumps with modular design

!cid_13a661a73c98169771f9d423411f4d78@schwarzerAll parameters of the modular eccentric diaphragm pump series EC-L 500 can be customized exactly to individual requirements. The pump heads are manufactured from highly resistant PPS. A wide variety of materials is available among the elastomers (EPDM, FKM, FFKM, silicon, PTFE, etc.) – depending on the intended purpose.

The options for motors lats from the economically prized standard drive to extremely long-lasting brushless motors and on to stepping motors with high-precision metering function.


HNPM: Hermetic micro annular gear pumps

mzr-4661-tech-zeichnungThe magnetic driven, hermetic series of micro annular gear pumps has been extended with regard to size and drive options. These pumps are suitable for handling

  • crystallizing,
  • air or moisture-sensitive liquids

because the pump has no shaft seal. This feature is made possible thanks to a liquid-separating cup surrounding the magnetic drive. Long service life, leak-free operation, low energy consumption and an integrated speed controller characterize this pump series of the German HNP Mikrosysteme GmbH just like the compact measurements of the pump with a minimum diameter of 22 mm and a minimum length of 69 mm.
