The Keller in-sump magnetic separators are ideal for metalworking operations machining cast iron or steel. Install one or two in-sump magnetic separators close to the inlet of the coolant pump or the inlet to a Keller tramp oil pump/separator.

The basic Keller in-sump magnetic separator consists of a powerful rare earth magnetic rod attached to a flat circular magnet. To mount the magnetic rod horizontally in the sump, place the flat circular magnet against the side of the sump. To mount the magnetic rod vertically, place the flat circular magnet against the base of the sump. To clean the magnetic separator, remove from sump and wipe the collected chips into a chip drum. Note: Wear hand protection. Cleaning time: about 1 minute.

The 1-inch diameter rare earth magnetic rods with circular magnet attached are supplied in two lengths:

        4″ RodSM-104
        9″ RodSM-109


Two optional accessory items are offered:

  1. A handle which threads into the end of the magnetic rod, for convenience in installing and removing the rod assembly
  2. A stainless steel sleeve which slips over the magnetic rod to assist cleaning the collected chips when the assembly is removed from the sump. The stainless steel sleeve is recommended if the in-sump magnet is cleaned frequently.
