Lutz-Jesco Dosing Pump LB 110

Mortal danger from electric shock!

Live parts can inflict fatal injuries.

Before carrying out any maintenance work, always disconnect the dosing pump from the power supply.

Secure the dosing pump from accidental power-up.

The protective conductor (earth) may only be removed during the last step.

After maintenance work, all earthing measures must be restored.

Caustic burns or other burns through dosing media!

DANGER! Mortal danger from electric shock! Live parts can inflict fatal injuries. Before carrying out any maintenance work, always disconnect the dosing pump from the power supply. Secure the dosing pump from accidental power-up. The protective conductor (earth) may only be removed during the last step. After maintenance work, all earthing measures must be restored.

WARNING! Caustic burns or other burns through dosing media! While working on the dosing head, valves and connections, you may come into contact with dosing media. Wear the recommended personal protective equipment. Rinse the dosing pump with a medium (e.g. water) which does not pose any risk. Release pressure in hydraulic parts. Before connecting the mains supply, connect the dosing lines. Check that all the screw connections have been tightened correctly and are leak-proof.

CAUTION! Danger of personal injury and material damage! The dosing pump can generate a pressure that is many times the rated one. The dosing medium can escape in the case of material failure or wear on the dosing head, the connection pipe or the seals that are used. Carry out maintenance work at the recommended intervals.

DANGER! Danger to life through explosions! Sparks may be formed during repair work by contact between tools or components. Only use tools which are suitable for use in explosive risk zones 1 and 2.

DANGER! Danger to life through explosions! Friction in parts of the dosing pump or system which are made of non-conducting plastic, can cause electrostatic charging. Clean plastic parts carefully with a damp cloth.

DANGER! Danger to life through explosions! The dosing pump can run hot if there is not enough oil. This could result in explosions occurring in explosive risk areas. Regularly check the oil level. If oil is leaking, the leak must be immediately fixed and the dosing pump taken out of operation. Change the first filling after 5,000 operating hours or 1 year, whichever comes first.

Precondition for action: A suitable oil collecting tank is held ready. Gear oil of the viscosity class ISO-VG460 (SAE 140).

Unscrew the closing screw (1) from the oil outlet (3) and remove the seal (2).

Let all of the gear oil drain from the housing.
