Moroso Radius Tooth Dry Sump Pump Pulleys

Moroso Radius Tooth Pump Pulleys are designed to work more efficiently and use less power to drive dry sump pumps. They're anodized black and accept a 1" wide drive belt. Offered in a variety of sizes, most drive ratios can be achieved. All pulleys are made to accept a .625" shaft and include four set screws to lock the pulley in a positive manner.

Moroso Radius Tooth Pump Pulleys are designed with the same 8mm tooth technology, and they add to the efficiency of the entire round tooth drive combination. Available in sizes that provide the ratio you want, as well as allow adjustment of the centerline measurement between the pump and crankshaft center. This benefits tight-fitting conditions while still having the correct drive ratio. Moroso Drive Pulleys fit any 1" mandrel with a .125" keyway slot.
