These pump units with integrated timer control the pressure conditions in the suction probes automatically according to the preset time cycles. In adaptation to the intended application, the suction probe system can be supplied with a weekly timer for free programming of 7-day cycles, or with a year-time timer for annual control cycles.
Thanks to the dust and jet-water-tight housing, as well as the power supply via a position-independent accumulator, these pump units are also ideally suited for outdoor use. Both wall and pole mounting are possible.
The diaphragm pump with neoprene diaphragm and pump head made of hostalen is durable and maintenance-free.
