Benefit From Accessories in the Laboratory

Silencer

Although quiet by design, KNF lab pumps can be equipped with silencers to further reduce the sound of your pump.

Pressure Control Valve

Suitable for use with either liquid pumps or gas pumps, control valves can be used to keep the system pressure constant, as a pressure relief valve to reduce pressure peaks or as a means to control liquid flow through the pump.

Foot Switch

Used with the LIQUIPORT® and SIMDOS® RC and RCP model liquid pumps the footswitch allows for hands-free actuation. The use of a foot switch is especially useful when performing repetitive dosing and metering tasks.
