OEM Diaphragm Liquid Pumps
Maximum Performance with Minimum Pump Size
KNF transfer pumps combine maximum performance with minimum size. Chemical-resistant materials enable the pumps to convey almost any type of liquid, whether neutral or corrosive.
Dry-run Safe
They are dry-running, self-priming, maintenance free, and available with various hydraulic connections.
