Self-priming centrifugal pumps, designed for pressurization, gardening and irrigation activities and underground extraction (also from wells) and rainwater reuse in residential building service and for irrigation activities in agriculture with Jet 200, Jet 300, Jet 151 and Jet 251 models. The pumps work without problems even if there are small sandy impurities or air bubbles in water. The pump body is in cast iron for the Jet, in stainless steel for the JetInox or in technopolymer for the JetCom. All the models are able to increase the pressure of the water withdrawn as well as from wells also from tanks or cisterns to be used for example to water vegetable gardens and gardens for free (without using the water of the aqueduct).
