Controllers of pump AquamotoR AR PC-15 allow to automate work of pumps. They switch-on pump at pressure decrease in water supply system (at opening of cranes etc.) and switch off the pump, at the water consumption termination (closing of cranes etc.) Besides, the controler protects the pump from its work without water («a dry course»). The controler is supplied by function of an automatic restart. Controlers are intended for pumping a clear water which is not containing firm particles. In the presence of firm particles, on a controler input it is necessary to install the filter. The Pressure gauge on the controler provides visual control of system pressure of water supply.
