Why choose a dosing pump
The dosing pump is to the traditional pump what the stopwatch is to the hourglass. It is at the same time a pump and a liquid end: it transfers a liquid and measures the dose at the same time.
Characteristics of a dosing pump
Dosing pumps belong to the family of reciprocating volumetric pumps. Differing from centrifugal pumps, which generate speed, dosing pumps generate volume.
Corrosion table
The resistance to corrosion is a function of several parameters such as the chemical concentration, temperature, mechanical constraints, environment, etc.
The drive mechanism of a dosing pump
The 3 principal components of electro-magnetic and electro-mechanical dosing pumps.
Liquid end and diaphragm of a dosing pump
The plunger liquid end and the diaphragm liquid end, the mechanically and hydraulically activated diaphragm.
The mechanical assembly of a dosing pump
The 3 principal mechanical components of electro-magnetic and electro-mechanical dosing pumps.
Properties of fluids
The question of the physical properties of fluids arises during the selection of a dosing pump (viscosity for example) as well as when calculating the dimensions of its installation (notably the NPSH calculation).
The correct installation of a dosing pump
Flow and pressure laws, traps to avoid, NPSH calculations, good and bad installations
