Thanks to the numerous experiences in the environmental field and to many laboratory researches, Hydrogea has brought to light a series of pneumatic pump dedicated both to the pumping of groundwater and to the recovery of LNAPL.The pneumatic pumps realized by Hydrogea are:- pneumatic pump total fluid (top inlet)- pneumatic pump total fluid (bottom inlet)- active skimmer.If required, the dimensions of the pumps can be modified.The products, realized in our laboratories in Mantova, are entirely manufactured in AISI 304 stainless steel and bronze. Whilst trying to fulfill his customers requests, Hydrogea knows how the easy use of its products is important. The dimensions are in fact restrained (48mm diameter), so that the systems can be adapted any type of piezometer or well. The pneumatic systems have been realized with care and particular attention to the simplicity of construction and, therefore, to the simplicity of maintenance.Control panels for pneumatic systems guarantee all models functioning. These panels are powered in two different ways: pneumatic or automatic. If required, the features of the panels can be modified.
