Control
The synchronous motor of the pump operates at a fixed speed of 20 rpm. This cannot be changed.
If smaller amounts of water are to be dosed or a smaller flow rate is required, the SP 1500 can be
controlled by a timer. For exact dosing, a digital timer, programmable in minutes, should be used.
