High-pressure dosing pumps

Dosing pumps


Knauer dosing pumps deliver stable and precise solvent flow for dosing of aqueous or organic media. Pressure ratings of up to 400 bar and chemical resistance to a wide range of materials make them the perfect choice for dosing applications.
 
Exchangeable pump heads for flow rates up to 1000 ml/min and pressures up to 400 bar make it possible to easily adapt the pump to changing performance requirements and allow simple maintenance.
