Leimbach pump motor options?

[Espeefan]

Odd as it sounds, I saw at least one guy running a stock Tamiya silver can on his Stahl bucket dozer's pump. Same thing happened to his motor. Oil got inside it, and shorted it out. If it works good, and it looked like it did, from the videos he posted, it'd be a nice, cheap option. Sorry I really can't offer any help on finding a brushless motor. I always thought most brushless motors, driving pumps, had remote mounted motor plates and ran a belt drive to the pump, via sprockets?
