Water forcing in automatic drink distributors/coffe machines. Water nebulization + insecticide in fixed timer installations for cattle, pig, poultry breeding. Water nebulization + anti-mould/fungicide in fixed installations, in silos or mobile installations in agriculture sector for treatment of grain, corn, etc. Water forcing in solar panels ( this series is particularly suitable for this sector because of its high hydraulic efficiency and low electric power absorbtion). Water forcing with disinfecting liquids addittive in tubes cleaning that pipe beer into distributors in bars, restaurants, pubs, etc. Water forcing in small autoclaves. Demineralized water forcing. Water nebulization in small installations for greenhouses' irrigation. Liquid gas carrying (Freon - GPL, etc.) Water forcing + detergent liquids in industrial machinery for floor cleaning. In each application where low capacity is required (2 ÷ 16 l/min) together with average pressure of (15 bar) and high self priming characteristics. Performance data: Capacity: 2 ÷ 16 l/min.; Pressure: max. 15 bar; Temperature max water and low viscosity liquids: 40° C (150° C by request) for medium viscosity liquids; Viscosity: a standard pump from 1 to 60 cP (on request: up to 3000 cP); N.P.S.H.: 5 m.
