0.6 GENERAL NOTES
0.6.1 CHARACTERISTICS OF THE PUMPS
ASTRA evo
pumps are air-operated, double-diaphragm positive-displacement pumps, designed and
manufactured for pumping fluids that are chemically compatible with the construction materials of the
pump. The characteristics of the fluid (pressure, temperature, chemical reactivity, specific weight, viscosity,
vapor pressure) and the environment must be compatible with the pump characteristics.
The best knower of the fluid is who buys the pump. The buyer is responsible for choosing the materials used
for the parts in contact with the fluid.
The configuration of the pump (wetted parts) is defined in the ordering phase and is indicated on the
nameplate.
ASTRA evo
pumps are suitable for pumping corrosive, abrasive, aggressive, flammable, cut-sensitive
chemical fluids, or with solids, such as acids, alkalis, alcohols, solvents, emulsions, oils, fuels, lubricants,
sludge, industrial sewage , enamels, varnishes, glues, water based fluids (containing suspended solids),
additives, detergents.
Chemical composition of the pumped fluid, concentration, temperature, amount of abrasive solids can
radically change the applicability of the configured pump or significantly reduce its duration. ARGAL
assumes no responsibility in this regard.
