Johnson Impeller pumps F7B-5001 mechanical seal

Johnson Automatically Controlled Pumps with Electromagnetic Clutches With a pump with an electromagnetic clutch, you have the power you need at the touch of a button without having to be at the pump. In conjunction with a vacuum switch (recommended when used as a bilge pump), the clutch disengages automatically as soon as the pump draws in air, preventing dry running and damage to the pump. Automatically controlled pumps are available in sizes 1" to 2 ½" (20 l/min to 625 l/min). Clutches 12 V or 24 V. Wear parts can be easily replaced and Service kits are available for all standard models. Vacuum switch available as an accessory, see page 45. Clutches must be ordered separately.
