Johnson Pumps with Electromagnetic Clutch for Heavy Duty ApplicationsWith 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. When used in conjunction with a vacuum switch (recommended when used as a bilge pump), the clutch automatically disengages when 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). Coupling 12 V or 24 V. Wear parts can be easily replaced and service kits are available for all standard models. Vacuum switch available as accessory. Coupling must be ordered separately.Specifications:Pump body: bronze Connection for vacuum switchShaft: stainless steel Shaft with permanently lubricateddouble ball bearingsSeal: mechanical sealCam: full or partial combConnection: 1' BSPClutch: Electromagnetic 12/24 V DCPulley: 2xA or 1xB groovePulley Ø: 178 mm / 7"Impeller: 09-1028BWeight: 6.9 kg - 15 IbsDimensionsLength: 226 mm - 8.9'Height: 120 mm - 4.72'Width: 93 mm - 3.66'
