Can I apply pressure at the inlet of the pump head and set the eluent under pressure before the pump?

KNAUER pumps can also work with pressure applied at the pump head inlet if this pressure remains below 3 bar. If you intend to apply a higher pressure, modification of the pump head inlet bushing is necessary. Please contact support@knauer.net and provide the details (serial number) of the pump.
