3. GENERAL NOTES
The diaphragm pumps are air-operated, double-diaphragm positive-displacement pumps, designed
and manufactured for pumping fluids that are chemically compatible with the constructive materials
of the pump. The characteristics of the fluid (pressure, temperature, chemical reactivity, specific weight,
viscosity, vapor pressure) and of the environment must be compatible with the pump characteristics
and are defined in the ordering phase. Pressol is not responsible for the pumped liquid. The customer
must ensure that there is compatibility between the pumped liquids and pump materials.
The diaphragm pumps are self-priming; at start-up the pipes can be empty.
The declared dry negative suction is referred to intake of water at a temperature of 20°C/ 68°F. The
priming time and the diaphragm’s life depend on:
- the suction circuit (total length and diameter)
- specific weight of the pumped fluid
- viscosity of the pumped fluid
- negative suction: max 5.000 cps (at 18°C / 64,4°F)
- below head suction: max 50.000 cps (at 18°C / 64,4°F) Diaphragm pumps may be used dry
Diaphragm pumps cannot be used to generate a vacuum.
Make sure that the physical-chemical characteristics of the fluid have been correctly evaluated.
