Linn-Pumpen GmbH

series FOM Gear-pumps with electric motor

Construction
Self-priming electric-gear-pumps, bellhousing with foot-flange, pump-casing in cast iron. Gear-pumps series FOM with motor-power up to 18,5 kW. Suction- and pressure-ports whitworth pipe threads - opposite 180°. For type FOM 5.. SAE-flange optionally.

Applications
Industrial applications, for example:
Lubrication systems, coolant feed in machine tools, heat transfer, test bench and many more.

Example of liquids suitable for transport
Pure, non-explosive liquids, not corrosive against pump materials, without any solids. The liquids to deliver, must have lubricating characteristics.
oil, mineral oil, synthetic oil, adhesives, sealants, polymers, diesel, paints, inks and many more.
