The tools necessary for a normal maintenance of the electropumps are the following:
• Allen screw keys of : 4, 5 and 6 mm
• Cross screwdriver
• 2 screwdrivers
• Hexagonal keys of: 8 and 17 mm
The pump does not start:
• Loss of electric power supply (check if the fusibles have broken or a protection relay of the circuit intervented);
• The selection switch is turned OFF (turn ON);
• Loss of phase (check the connection);
• The impeller is blocked;
• Mechanical seal or ball bearing seized.
The pump does not stop:
• Failure to the stop regulator (clean or replace the stop regulator).
• The pump is not able to empty the tank till the stop level: there may be leaks in the installation; absence of
the non return ball valve, to avoid the liquid reflow; necessity to replace the pump with another one of bigger
capacity.
The pump works, but the delivery is scarce or inexistent:
• The pump works with a wrong rotating direction (this is possible only with threephase motors);
• Check the wear conditions of the hydraulic part, if necessary replace the parts;
• The pump is closed by an air-pocket (switch off the electropump and restart it after few minutes);
• The delivery pipe is obstructed, the non return ball- valves or the sluicegates are in part closed.
The CE conformity declaration is available on our website: www.drenopompe.it, on the product pages.
