3m 1 Quart Perfect-It Ultrafine Machine Polish AVI6_F2VKI80

With an electro-magnetic clutch you will have pumping power whenever needed, at a push of a button, without being at the pump. Combined with a vacuum switch (recommended for bilge pump application), the clutch will automatically disengage whenever the pump starts priming air, thereby preventing dry running and pump damage. Automatically controlled pumps are available in sizes from 1 in. to 2ツス in. (20 l/min to 625 l/min), with clutches in 12 or 24-Volts. Wearing parts are easily replaceable and service kits are available for all standard models. Vacuum Switch as extra accessory, see page 44. Clutch to be ordered separately.
