Maintenance
• Periodically measure the supply current voltage to verify that the pump is operating at the correct voltage.
• The electrical resistance of the motor should be checked at least once a month. If the resistance of the motor is less than
100M Ohm, the winding of the electric motor should be dried and the tightness of the wires, etc. should be checked.
• The oil capacity in the bottom cover should be checked every 500 hours. Therefore, place the pump horizontally. If necessary,
add oil as specified in the technical characteristics table of the pump through the opening provided for this purpose.
• If the presence of water is established in the oil (whitish emulsion), or if the oil contains solid particles (mud, etc.), it means
that the seals are defective. Their replacement is required.
• The amount of oil in the lower pump casing is specified in the pump's technical specifications.
• If the pump flow is decreasing, the clearance between the suction disk and the impeller should be checked. The recommended
clearance is given in the pump technical specifications.
