It should be noted that it is very important to realize systems with pipes well arranged, identifiable, suitably equipped with shut-off
valves, with comfortable compartments and passages for operators who must inspect their status (since the pressure developed by
the pump may promote failures to the system if it is of defective construction or worn).
OPERATORS FOR INSTALLATION AND START-UP
interventions to be carried out only by skilled personnel who may delegate to others some operations in accordance with specific
evaluations (required technical skills: plumbing, pneumatic and/or electric qualification as appropriate)
OPERATORS FOR USE AND MAINTENANCE
interventions to be carried out by generic operators (after being instructed on the correct use of the equipment):
- pump start-up/stop
- valves opening / closing with stopped pump
- casing emptying and washing by means of the prearranged valves and pipes
- filtering elements cleaning interventions to be carried out by skilled personnel (required technical skills: general knowledge of
the mechanical, electrical, chemical aspects of the equipment supplied by the pump and of the pump itself):
- environmental conditions check
- pumped fluid conditions check
- inspections of start-up/stop devices
- detection of malfunctions
OPERATORS FOR REPAIR
work to be carried out by generic operators supervised by skilled personnel:
- pump stop
- valves closing
- emptying of pump casing
- pipes disconnection from the connections
- unlocking of fastening screws to the base
- washing with water or suitable solvent as appropriate
- transport
Work to be carried out by skilled personnel (required technical skills: notions of mechanical processing, sensitivity with regard to
damage to parts for impacts or abrasions during handling, familiar to tighten bolts on different plastic/metal materials, use of
precision measuring instruments):
- casing opening and reclosing
- removal and replacement of damaged parts
DISPOSAL
For type of material: separate plastic parts from metal parts and dispose of by authorized companies.
TROUBLESHOOTING AND POSSIBLE CAUSES
DEFECT
CAUSE
SUGGESTION
1
The pump
does not start
Circuit without air
Check the circuit (valves, connections, regulators, etc.)
Insufficient air pressure
Adjust the air pressure
Insufficient air flow rate
Check that the pipes and fittings have suitable passages
Damaged control valve
Replace
Damaged pneumatic
distributor
Replace
Pump delivery or intake
closed
Open some valves, or remove the pipes and check if the pump starts
Damaged discharge cover
Replace
Broken diaphragm
Check if air comes out of the product delivery pipe, if yes replace the
diaphragm.
2
The pump
works butit
does not
pump.
The balls do not close.
Disassemble the manifolds and clean the seats or replace the balls and the
seats.
Excessive intake height.
Reduce the intake height.
Too viscous fluid.
Install pipes with greater size especially for intake and decre- ase the pumps
cycles.
Clogged intake.
Check and clean.
3
The pump
works with
slow cycles
Excessively viscous fluid.
No remedy.
Clogged delivery pipe.
Check and clean.
Clogged intake.
Check and clean.
4
The pump
works
irregularly.
Internal pneumatic
exchanger clogged or
defective
Replace the pneumatic exchanger.
Worn shaft.
Replace the pneumatic exchanger.
