CAUTION
Vibration generated by pump operation should be absorbed. Take it into consideration when mounting it.
When using the pump in submerged position, follow the steps below:
- Verify the corrosion resistance of each component of the pump. DO NOT expose the pump to any fluid
for which it does not have proper corrosion resistance.
- Exhaust should direct outside, not into the fluid in which the pump is submerged.
The running pump may generate noise. Its level will depend upon conditions of use (kind of fluid being
pumped, supply air pressure and discharge pressure).
The end of the hose must be equipped with a pit, a protection box, etc. at the end of the hose in case the
diaphragm gets damaged and a leakage of the fluid follows.
Pump exhaust should be directed to a safe place, away from people, animals and food.
Before putting the pump into operation as well as after some hours of pumping, the housing bolts have to be
fixed according to the torque data of the following schedule, as the eleme
nts of construction “settle”.
Fixing the bolts is necessary as well after longer periods of stoppage, at extreme temperature variations, after
transport and dismantling the pump.
