M / MF
Electrically operated gear pump units for oil circulation lubrication systems
MF single-circuit gear pump units are used in small oil circulation lubrication systems with pressure ranges up to 65 bar (940 psi) and high viscosities up to 2 000 mm2/s. The pump is vertically mounted on the reservoir.
MF gear pumps come with integrated pressure relief and venting valves that feed into the internal return oil connection in the adapter flange. In case of trapped air, the venting valve opens. In case of excess pressure, oil is relieved to the return oil connection via the pressure relief valve.
