Filling and dosing technology with mzr-pumps

Filling and dosing technology

Standard, tubular and circular vials are precise measuring instruments which are filled with a mixture of a low viscous, highly volatile and non-lubricating gasoline-dye. For safe dosing are micro annular gear pumps of high pressure series in operation. > read more

Shrink sleeve manufacturing with micro annular gear pumps by HNP Mikrosysteme

Shrink sleeve manufacturing

Precise and reliable coating of solvents on shrink sleeves is realized through high performance pumps like mzr-4609 EX in ATEX design which work synchronized to the belt speed. > read more

Hard disk drives with FDB-Technology with mzr-pumps

Hard disk drives with FDB-Technology

In the production of oil-bearing hard disks, the size is what counts. Pumps of the magnetic hermetic series, a few microliters of liquid are dosed directly into the FDB (Fluid Dynamic Bearing) systems. > read more
