Construction
Self-priming external gear pumps are designed for industrial
applications. Positive displacement pumps with a wide range
of capacities. Suction- and pressure-connections Whitworth
pipe threads - opposite 180°
(Series D5xx also available with SAE-flange).
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
