SEN series close coupled centrifugal pumps are with single impeller, which manufactured according to European standards EN733; SEN series are very extended: the different performances curves allow a right choice of the optimal model following all kinds of specific demands in several fields as: watersupply for living uses; industrial uses and general water plants projects; water supply; spray irrigations and watering; pressure sets; heating and air-conditioning plants; any other use for liquid decanting.

The pumps must be installed in enclosed places, or at least protected against inclement weather.
