The 070-3240 pump belongs to the RSA Oil Pumps series and is manufactured by Danfoss to move kerosene or light oil in hydraulic automation loops. Its single-stage design limits pressure ripple and simplifies service tasks. A delivery rate of 82 L/h supports steady flow to small burners or actuators, while the factory-set discharge of 7 bar allows immediate installation without adjustment. Clockwise rotation, denoted as R, must be matched by the drive motor, and the 7/16 in shaft diameter fits common flexible couplings. The unit accepts fuel mixtures containing up to 100 percent biofuel so alternate energy sources can be used without hardware changes. Electrical load is 70 W at nominal duty, information that helps size power supplies and estimate heat dissipation. Reliable lubrication begins once the pump reaches its minimum operating speed of 1400 rpm, preventing cavitation under light load conditions.
The integral filter offers 75 cm² of surface and stops particles larger than 150 µm to protect downstream components. A single-pipe connection returns excess oil internally, reducing external plumbing and leak points, and the L-type nozzle outlet mates directly with standard burner fittings. The pump withstands system pressures up to 21 bar and can turn at speeds as high as 3600 rpm, enabling use with a broad range of drive ratios. Maximum starting torque is limited to 0.22 N·m, so small fractional-horsepower motors can bring the unit up to speed without stalling. These features combine to provide compact, low-maintenance oil delivery for automated hydraulic equipment.
