The ProMinent diaphragm metering pump<\/strong> for the process industry is a hermetically sealed pump for aggressive media. The group includes two models for different purposes: EXTRONIC for hazardous areas and MAKRO TZMb for high flow rates. Flow rate: 1 to 2,100 l\/h; back pressure: 25 to 1 bar.<\/p>\n

ProMinent diaphragm metering pump: which model to choose?<\/h2>\n

The task determines the model. If the pump is installed in a zone with an explosive gas atmosphere, choose EXTRONIC. It meters up to 60 l\/h at pressures up to 25 bar.<\/p>\n

If a high flow rate is required, choose MAKRO TZMb. It meters 260 to 2,100 l\/h at pressures of 12 to 4 bar. Motors for hazardous areas are available for it. The general operating principle of ProMinent metering pumps is described on the ProMinent brand page<\/a>.<\/p>\n\n\n\n\n\n\n

The pump is supplied with one or two dosing heads. Two heads operate in push-pull mode. Up to four metering units with different flow rates can be combined in one assembly; five gear ratios are available.<\/p>\n

Where is the ProMinent diaphragm metering pump used?<\/h2>\n

The manufacturer lists onshore and offshore oil and gas production, refineries, and the chemical, petrochemical, pharmaceutical, cosmetics and food industries. Safety when handling aggressive chemicals is covered in the article \u201cSafety first: modern systems for metering and packaging aggressive chemicals\u201d<\/a>.<\/p>\n

For pressures above 25 bar, use ProMinent hydraulic diaphragm pumps<\/a>. For flow rates up to 1,040 l\/h and pressures up to 16 bar, you can also use Sigma motor-driven pumps<\/a>.<\/p>\n
