The MP 204 protects pump motors against incoming station power supply issues such as: undervoltage, current unbalance, and other variations in power supply. So even if your external power supply is not entirely steady, your SP pump will remain as reliable as ever. Very importantly, the extra protection also reduces wear, thereby prolonging the motor's lifespan.

Reduced power consumption is a strong indication that the pump is about to run dry, so the MP 204 will immediately stop the pump if the power consumption drops below 60 percent. And with SP pumps, the Tempcon temperature sensor ensures that the pump is stopped if it becomes too hot – for example if a foreign object jams the pump.
