A diagnostics table is provided below that indicates the main anomalies, the probable causes and the possible solutions. 

If you were not able to solve the problem after consulting the diagnostics table, do not try to find the fault by disassembling 

machine parts but contact the Dropsa technical office and report the anomalies that have been discovered, with a detailed 

description. 

 

 

 

 

 

 

 

 

 

 

PROBLEM 

CAUSE 

SOLUTION 

The electric pump does 

not deliver lubricant. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The electric motor is not operating. 

 

 

 

 

 

 

 

 

 

The tank is empty. 

 

 

 

The pump does not prime. Cause for the 

pump not priming: 

 

The motor is rotating in the inverse 

direction (clockwise); 

 

The motor is rotating in the correct 

direction, but the spatula is not rotating; 

 

Air bubbles in the lubricant. 

 

The pressure control valve (bypass) was 

calibrated at a value that is too low 

Presence of dirt in the non-return valve 

Check the connection between the motor and the 

electric power supply line. 

 

Check the motor windings. 

 

Check that the motor terminal board connection 

plates have been positioned according to the power 

supply voltage. 

 

Fill the tank. 

Attention: if the tank emptied itself and the electric 

signal indicating that the minimum level was reached 

was not given, check the minimum level contact. 

 

Remove the tank cover and check that the spatula 

rotates clockwise and moves the lubricant; otherwise, 

invert two of the three motor phases. 

See above. 

 

 

 

 

Disconnect the pump delivery pipe and bleed the 

lubricant until the air bubbles have been eliminated. 

The pump does not 

pressurise. 

There may be dirt on the pumping element 

check valve cone. 

Clean the pumping element check valve cone and 

seat, bleeding the lubricant. 

No minimum level 

signal when there is no 

lubricant in the tank. 

Minimum level incorrectly regulated. 

Check the correct operation of the level probe as 

follows: 

Check the correct level adjustment of laser probe. 

Minimum level 

selection, with lubricant 

below the minimum 

and pump operating. 

Minimum level incorrectly regulated. 

The control panel lamp always remains on: check the 

electric connection and replace the laser probe if 

necessary. 

 

9. MAINTENANCE PROCEDURES 

 

The pump was designed and built in order to minimise maintenance requirements. 

To simplify maintenance, it is recommended to install it in an easy to reach position. 

 

Periodically check the pipe joints to detect any leaks. Furthermore, always keep the pump clean to be able to quickly detect 

any leaks or defects. 

 

Check if the loading filter is clean after every 2000 hours of operation. 

The machine does not require any special equipment for any control and/or maintenance activity. It is recommended to use 

tools and personal protective devices suitable for use (gloves) and that are in good condition according to current regulations to 

prevent damage to people or machine parts. 

 

 

 

 

ATTENTION

Make sure that the electric and hydraulic power supplies are disconnected before carrying out any 

maintenance work.
