Danfoss Oil pump RSA60 070L3362

The Danfoss RSA60 oil pump (SKU 070L3362) is a gear pump designed for small and medium-sized household burners with a fuel consumption of up to 255 l/h. It features a built-in regulator with a shut-off function and a special spring for use as a transport or feed pump. The pump operates within a pressure range of 5500–21000 mbar, with a factory-set pressure of 7 bar. It supports a viscosity range of 1.3–75.0 cSt in the suction line and has a filter area/cross-section of 75/150 cm2/microns. The shaft is made of EN225 material, and the pump is suitable for ambient temperatures from -20 to 70 °C, storage temperatures from -25 to 70 °C, and fuel temperatures from -10 to 70 °C. The shaft rotation speed ranges from 1400 to 3450 min, with a maximum starting torque of 0.24 nm.

When selecting a replacement oil pump of this type, ensure that the pump's pressure range, shaft rotation speed, and fuel consumption capacity match the burner's requirements. Verify the shaft dimensions and type (e.g., EN225) to ensure compatibility with the coupling. Check the pump's mounting flange and inlet/outlet connections against the existing installation. Also, confirm that the pump's factory-set pressure aligns with the burner's specified operating pressure, and adjust if necessary.

Common failures of this pump type include loss of pressure due to worn gears or seals, leading to incomplete combustion or burner shutdown. A clogged filter or suction line can cause cavitation, resulting in noisy operation and reduced fuel flow. Leaks may occur at the shaft seal, causing fuel to drip and potentially leading to fire hazards. If the pump fails to start or struggles to reach pressure, check for debris in the inlet, proper shaft rotation, and correct electrical connections to the motor.
