Double Control System: a Flow Switch and a Pressure Switch. When the flow is too low, SJLM can keep constant pressure and water flow in the system so that it eliminates the temperature fluctuations.
Protection against dry-running: SJLM stops after 8 min of dry-running operation.
Ignition Protection: When a plug is inserted the pump will start working after 3 sec. In the case a socket wont emit sparks.
Anti-clogging: If the pump is not being used for a long time, after every 72 hours it will automatically go on for 10 sec. to avoid jamming.
