REPAIR AND MAINTENANCE PROCEDURES
TORQUES NECESSARY FOR THE PROPER FUNCTIONING OF THE PUMP
For proper operation of the pump and to prevent accidents which may
damage equipment and in the worst case, people, you must periodically
review the torques of the diaphragms covers and the DIRECTIONAL
VALVE. In the next table are shown the appropriate torques for this
purpose:
CAUTION!: DO NOT OVERTIGHTEN FASTENERS.
DIAPHRAGM MAINTENANCE
Before any intervention: DISCONNECT AIR SUPPLY OF THE PUMP.
IT IS NOT NECESSARY TO REMOVE THE PUMP FROM THE FLUID LINE.
ANTICIPATE A POSSITE LEAKAGE OF FLUID INSIDE THE PUMP.
INSTALLING THE NEW DIAPHRAGMS - ASSEMBLING PROCEDURE
CAUTION: Follow next procedure to ensure the diaphragms are
correctly installed. If not followed diaphragm bead could be
extruded out of its housing with the resulting damage over the
diaphragm bead and thus possible fluid leaks or premature
diaphragm failure.
