New coolant system for bandsaw.
Bandsaw Pump. 12 volt brushless motor – 12 volt, .6 amp. Gear pump, no ratings for pump output. Head height well over 1 metre running off 6 volt, 300 ma.
For anyone interested, I’ve just replaced the coolant system on my BS–5 bandsaw.
Previously I used a fountain pump, but as the pump had to be submerged I found it messy and the magnet tended to clog up with the fine swarf the bandsaw produced, siezing the motor. I run the new bandsaw pump from a 6 volt, 300 ma power supply, the pump is of the gear type so the internal magnet isn’t exposed to the fine swarf. I mounted the pump external to the resevoir so cutting down on the mess when changing coolant. The pump delivers coolant to the head and then back to the reservoir in a continuous loop. A T barb diverts some of the coolant to a reticulation tap and then on to the hose supplying coolant to the bandsaw blade, turning the coolant tap on or off has no affect the continuous loop.
The filter system is comprised of four magnets mounted inside a small diameter PVC pipe. The PVC pipe is mounted at a very slight angle, and as the coolant flows over the magnets most (I hope) of the swarf is trapped. The coolant then flows through a reticulation filter which further filters the coolant before returning it to the resevoir. Time will tell how well the two filters work, at the moment all is working fine.

Incidentally, it;s not as noisy as it appears in the video
