PROBLEMS AND SOLUTIONS
A diagnostics table is illustrated below, where the main faults, probable causes and possible solutions to be immediately
activated are indicated (contact Dropsa).
In case of any issues and/or problems that cannot be resolved, contact the Dropsa Engineering Department rather than
searching for the fault by disassembling components of the pump.

MAINTENANCE PROCEDURES
The pump does not require special tools for any check and/or maintenance operations. In any case, we recommend using
tools and personal protective equipment suitable for the use (gloves, eye protection, etc.) and in good condition in
accordance with prevailing regulations in order to prevent damage to people or parts of the pump.
The unit was designed and built in a way to require minimum maintenance operations. In any case, we recommend always
keeping the body of the equipment clean and periodically checking the line joints in order to promptly detect any leaks.
ATTENTION: Before any maintenance or cleaning operation, ensure that the hydraulic and electrical supplies
are disconnected.
