Diaphragm pump handles aggressive, corrosive liquids


The compact SIMDOS 10 line of diaphragm liquid metering pumps handles aggressive and corrosive liquids. Available with four head material options, the line provides laboratory staff with simple operation with a user-friendly display and adjustable transfer parameters from a touch-control knob.

The line’s FT version features a PTFE head, a PTFE-covered diaphragm, and chemically resistant FFKM Kalrez valves, for the transfer of aggressive chemicals. An optionally available Chemraz-valve kit allows using the pump with highly concentrated acids such as nitric, sulphuric and hydrochloric acids and solvents such as TFH, DMF, DMSO and MEK.

Also available with heads in PP, PVDF or stainless steel, each pump in the line transfers liquids with a flow rate of 1-100 mL/min, and dose volumes of 1 mL up to 999 mL. In addition to fast and simple calibration, the pump offers long-term stability and consistent reliability throughout its lifetime. The pump head is situated outside the splash-protected IP-65 housing, providing a significant safety feature.

The pumps are safe to run dry and are self-priming up to 9.8 ft. water. Effective against pressures of up to 85 psig, the pumps transfer viscous media up to 500 centistokes (reduced flow rate above 150 centistokes). A streamlined design and small footprint allows the pumps take up very little valuable laboratory space. KNF Neuberger
