AUTOMATIC OPERATION OF A SUBMERSIBLE PUMP

Nearly all sewage pumps operate automatically according to the liquid level in the sewage tank. A manual pump requires a control paneland fl oat switch for automatic operation. EBARA submersible pumps feature built-in automatic operation mechanisms which makes controlpanels and fl oat switches unnecessary.
