ZM gear pump with electric drive

For circulating oil lubrication systems

ZM multi-circuit gear pump units are self-priming and valveless. They are used in oil circulation lubrication systems with 2 to 20 individual circuits. The lubricant must be returned to the reservoir through unused outlets. The pumps consist of an electric motor, a coupling flange, a coupling, and a gear pump. The pump can be installed separately from the reservoir or as a flanged pump on the reservoir. A special design with seals for horizontal installation below the lubricant level is available. The pumped liquids must have sufficient lubricity to ensure self-lubrication of the pump.

Some of these distribution pumps require a single-circuit priming pump, which operates separately. The priming pump limits the pressure drop in multi-circuit pumps and helps ensure a uniform flow. It is recommended to filter the oil before the distribution pump inlet.
